In recent years the flock of Brent Geese at Maidens has become a regular and growing feature. As the series of photos in the Photo Gallery shows, this flock has been closely monitored over the years by Angus Hogg. Now Angus has brought all the information on these geese at Maidens into a new article: the Maidens Brent Geese 
.
Back in 2018 Angus Hogg and Dave Grant saw and photographed an unusual looking Black Redstart near Maidens. It had the characteristics of an Eastern sub-species and so they submitted a detail report. Dave has produced the attached poster showing what they submitted and the outcome.
If like me you aren’t as up-to-date on your Siberian Chiffchaff identification as you’d like, then you’ll find the attached poster produced by Dave Grant essential reading. Using his photos of the bird that recently popped up in Auchenharvie and explanatory notes, you’ll be ready for when the next one pops up. Click on the icon to download the poster. Makes an ideal spousal Christmas present.
The discovery of a Chough just North of Turnberry lighthouse on January 30th 2019 came almost 90 years after the last totally reliable record of the bird in Ayrshire. A once widespread bird in Scotland, the numbers today have declined to the point where it hangs on in places such as Islay, Jura and Colonsay, with all of the former Scottish mainland haunts now unoccupied by breeding pairs.
In South-west Scotland, it would appear that the writing was on the wall from around the middle of the 19th century, when significant declines were noted by the ornithologists of the day. One comment made at the time stated that it had been abundant on all the rocky headlands of Scotland in 1835 but “had vanished nearly everywhere by 1865.” Choughs weren’t restricted to coastal Scotland as is exemplified by records of birds from inland localities such as Assynt, Glen Lyon, Glen Clova and the Ochils. These inland locations had, however, mostly been abandoned by the early 19th century.
In the mid 1800s some coastal cliffs still provided nesting sites for Choughs, and the South-west of Scotland continued to play host to the species. Robert Gray, in 1871, noted that the Chough could still be seen sparingly in the Rhinns of Galloway, along with Burrow Head and the Kikcudbright-Wigtown border. The cliffs around Portpatrick seemed to be a particular stronghold. However, Jack Gordon notes that, by 1870, the bird had vanished from Burrow Head, although it was still to be found on the Rhinns, which appeared to be its “headquarters.”
Within Wigtownshire, nesting pairs were still recorded from locations like Port Logan and the Mull of Galloway until 1919, with an estimate of 7 pairs claimed for the former site. The fate of the Ayrshire coastal birds mirrored that of their Wigtown cousins, since the bird was obviously showing a sharp decline in numbers by the middle of the 1800s. Gray comments that it had still been present at Culzean until at least 1850, but Charles Berry of Lendalfoot paints a gloomier picture. In 1908, he stated that he had seen nesting birds not far from Lendalfoot just a few years before, but that it was fast disappearing.
Gib Graham wrote that the bird had once been “very common” on Knockdolian Hill in the mid 19th century and placed the blame for its decline on the Jackdaw. The 1920s still provided a few Ayrshire records but usually of just one or two birds. Sadly, by 1929, Richmond Paton reported that “one, occasionally two pairs of Chough continue to breed in Ayrshire” – this was at a site which they, wisely, did not name, perhaps providing a clue as to one of the contributory factors in the bird’s disappearance.
So, just why did the Chough disappear from Ayrshire, and much of the rest of Scotland? Like most cases of extinction, the causes may be unclear and much-debated, and it’s often difficult to identify the main culprit. However, some factors do stand out as candidates leading to the Chough’s downfall. The Jackdaw was seen as a potential competitor by many ornithologists in the 19th century. Graham clearly points the finger at it. However, it seems unlikely to have been solely to blame.
For whatever reasons, game-keepers were said to have accounted for some birds, while the gun most definitely did remove birds from areas of the Rhinns of Galloway where Choughs were said by local farmers to be responsible for damage to their crops and “stooks.” It may be that the fashion for bird “collection” and egg-collecting, prevalent in the mid 1800s simply added the final nail in its coffin in areas where the bird’s numbers had dwindled seriously.
Undoubtedly, one of the most serious threats to the Chough came with the rapid changes experienced within farming as we entered the 20th century. Farm boundaries were extended further out, towards the edges of cliffs, removing the availability of rough, grassy swards on which Choughs could probe for invertebrates. Improvements in cattle rearing practices also meant that livestock would frequently be housed indoors now, and not allowed to feed outside in winter, removing yet another food source from the Chough – cow-pats. Probing within cow-pats could provide Choughs with access to parasites, passed through the guts of cattle. But, this source was also to be removed, with the arrival of new chemicals which killed off these “bugs.”
By the end of the 20th century though, Choughs still clung on in areas where the nature of both landscape and land use still afforded them a living: much of Wales, the Isle of Man, North and West Ireland. They are largely sedentary which raises the obvious question of where the Turnberry bird came from. It seems unlikely that Choughs will make a comeback any time soon in the South-west of Scotland, given the pressures they face, and the current Turnberry specimen provides us with yet another clear example of a beautiful bird which, like Corncrake and Corn Bunting in Ayrshire, can disappear all too suddenly from our lives.

IntroductionA survey in 2013 of most of coastal Ayrshire’s Stonechat breeding population was undertaken, mostly by volunteers from the SOC or RSPB, following the devastating effects of the 2010 and 2011 winters. With a run of milder winters from 2013 onwards, it was hoped that there might be some improvement, although the rate of recovery was unknown at that time.
Many observers continued to send records in on an annual basis, and it became possible to identify the rate at which some coastal territories were being reclaimed by this species. Fifteen stretches of coastline in particular were visited, when possible, during the breeding season and the number of pairs holding territory within each was recorded. Casual records for areas outwith those mentioned in Table 1, were also recorded, to give a rough idea of the overall rate of recovery in the county.
Although, in many cases, observers noted breeding outcomes, this article concentrates only on territorial occupation and those territories occupied by breeding pairs. In some cases, notes were also made on habitat alteration, particularly that which might have affected the presence of Stonechats.
A small band of observers, to whom I am very grateful, continued to provide information on coastal stretches southwards from Ardeer from 2014 to 2017, and a total of 15 such sites were covered regularly enough to enable the provision of data on the number of territories occupied in each (Table 1).
Table 1: Territorial occupation by probable or confirmed breeding pairs with 15 regularly visited coastal stretches. (N/C = Not checked)
The area of each of these stretches varies greatly, and it would be wrong to assume that all were visited with the sole intention of obtaining Stonechat breeding information. In many cases, observers were involved with other survey work at the time e.g. breeding seabirds, and took the opportunity to note the current state of play with Stonechats. However, a good idea of the location of Stonechat pairs within these sites was well known from previous years.
Although a general improvement in territorial occupation since 2014 was noted, there were some losses too. Three areas (Finnarts Point, Dove Cove and Bennane Lea) showed a negative trend with possible reasons being due habitat change or shortage of suitable habitat. The presence of two territories at Finnarts Point frequently alters, and the possibility of one pair moving into an adjacent area away from the coast is the most likely explanation for the disappearance of one pair. The territory at Dove Cove is marginal, with limited availability of nesting sites. Bennane Lea is harder to explain but, once again, movement into a nearby area, which was not covered, is a distinct possibility. The other area to record a drop in its recorded territories was Bogside/Ardeer, but this is such a large and difficult area to cover that the recorded results could be unduly pessimistic.
There was a slow and steady recovery in many places e.g. Dipple to Doonfoot, where the first indications of re-occupation came during late autumn as males took up territories and held on to them through the winter. Perhaps the most spectacular return came in the Pow Burn and Troon South Beach stretches where the abundance of gorse scrub and rough coastal grassland has been maintained. The fact that these areas, along with the Barassie to Irvine stretch, show a very positive trend is largely due to the excellent coverage provided by just one observer who has kept a very careful eye on the territories there.
As mentioned above, there was no requirement in the survey to note broods or brood sizes, although this was done in a few cases, but observers were asked to try to ensure territorial occupation/maintenance by Stonechats. Proof of this could range from a pair’s observed presence throughout the year to singing males regularly seen in the same area during the breeding season. Additional evidence might involve a bird watched carrying food to a likely nesting area or the vigorous defence of a possible nest site.
During 2013 no fewer than 36 coastal areas were visited and the results provided both a good comparison with 2010 figures – a baseline against which future results could be measured. Comparing like with like is always difficult over such a large geographical area and one or two changes occurred in the years following 2013.
Firstly, one or two sites were dropped or amalgamated e.g. Downan Hill and Lendalfoot, and Fig 1 below shows the change in the overall number of sites visited. Since 2013 the number of sites checked has fallen to a more manageable 17 – 2015 was unusual due to observer effort being poorer, but this picked up again in 2016. Secondly, it’s noticeable that the number of territorial pairs has risen (allowing for the aforementioned “blip” in 2015), returning to a much healthier position than that which existed in 2013.
Female Stonechat at Lendalfoot (A Hogg)
Very little habitat change occurred within any of the sites visited, apart from some minor scrub removal, but there would appear to be one or two points worth noting when it comes to the continued well-being of the species within Ayrshire.
The 2013 survey revealed that Stonechats breeding along the coast with Ayrshire had made only the slowest of recoveries in a few areas, and were still missing from many of their former haunts. Many, if not most, of the birds which breed in upland areas well away from the coast, appear to move out in winter as the food supply diminishes, and there are relatively few records of inland birds from November to March. On the other hand, coastal territories are maintained, often by pairs, throughout the winter period. This strategy works well providing winters are mild and the food supply holds up.
A prolonged period of severe winter weather will deplete the coastal numbers, but 2 consecutive winters, during which lying snow is glazed over by thawing and re-freezing, can prove lethal to a wide range of wintering birds. However, Stonechats, like many small passerines, have a high replacement rate, frequently raising 2 broods, so it’s maybe not too surprising to expect a breeding population to bounce back fairly quickly after a setback. Just how fast that recovery has been can be assessed from Fig 1.
2014 proved disappointing inasmuch as there was little sign of the species reclaiming ground, apart from the stretch between Troon South Beach and Ardeer. Territorial Stonechats were under-recorded in 2015, but both 2016 and 2017 show a steady recovery. In essence, it has taken between 5 and 6 years for coastal Stonechats to climb back to their pre-2010 level, with the first 3 or 4 years showing very limited or no recovery. For a bird which decides to over-winter on its coastal breeding territory, the risks are clear, but this hardy little passerine has demonstrated the ability to make a relatively speedy return after a serious setback.
Male Stonechat at Maidens (A Hogg)
None of these results would have been possible without the help of many local observers – I am extremely grateful for all your hard work in obtaining the data. A full list of observers appears at the end, but I would like to offer special thanks to Jean Anthony who continued to keep careful records for the stretches between Pow Burn and Irvine – a major effort, and one for which I’m very grateful. Others who contributed to the survey work include the following:- F Alison, J&B Anthony, G Brogan, A Brown, T Byars, E Forrester, A&A Gilchrist, R Hissett, N J Lawrie, B Lennox, E Leyden, H Martin, G McAdam, P McEwan, G Macdonald, J&S Montgomerie, D Rackham, G S Riddle, J Rogers, T&G Scott, the late A Simpson, C Smith, J Thomson, R Turner, R G Vernon and the late D Watt.
I apologise for anyone unintentionally omitted from this list.

Juvenile Green Woodpecker near Straiton, Ayrshire. August 2017 (A.Hogg)
The Green Woodpecker (P. viridis) was first recorded in Ayrshire in 1925 when one was heard calling from the Blairquhan estate woodlands. Unfortunately, the bird was not seen, but the person who heard it was, apparently, well aware of the species’ rarity in Scotland at the time. Indeed, the bird scarcely gets a mention in South-west Scotland before this, and national records remained at a low level until the end of the 1940s.
The second Ayrshire record came in 1961 when a pair took up residence in “Central Ayrshire” and remained in the area for a few years, when another bird was seen at Alton Albany, Barr, in 1962. Breeding was not proved, although several nest-holes were found. For a bird which can be fairly vocal in the early part of the Spring when it is setting up its breeding territory, it can also prove quite tricky to obtain clear proof of breeding since it often becomes very elusive during the nesting period.
1974 saw the next Ayrshire record when one was present in the Portencross-Hunterston area between March and August. Three more records followed in 1977, when an adult was watched carrying food in Knockdolian Wood, this representing the first “probable” breeding record. A pair was present throughout the year “near Kilwinning” (possibly Montgreenan), and a single was observed at Sundrum in late May.
From here on, for a few years, the pace of colonisation picked up. It seems likely that a pair bred at Portencross during 1978, where a juvenile was seen on the 20th August. A pair remained at Knockdolian, and other pairs were noted at Kilkerran, Kelburn and Blair, all locations with large stands of suitable, mature woodland. Two Spring records of single birds were also recorded from the lower Girvan valley. An even bigger number of records came in during 1979, with the bird stated to have bred at 3 or 4 locations (Portencross-Hunterston, Fairlie and Knockdolian). It was also seen on single dates at 4 other locations – during this period the species was steadily expanding its range Northwards in Scotland.
In 1980 a pair reared 3 young at Hunterston, with other pairs noted at Portencross, Auchinleck estate and Knockdolian, and single records at 4 other sites. Pairs or calling birds were reported from the now customary areas of Hunterston, Portencross, Blair and Kelburn in 1981, as well as in Dailly and Dusk Glen. Only one record came from a “new” location, Glen App, during September.
A marked reduction in records came in 1982, following a harsh winter – something which Green Woodpeckers don’t appear to handle too well – with only 3 reports of individuals at Largs, Kelburn and Currarie Glen. Although 1983 and 1984 provided a wide scatter of records, the latter year including 2 birds at Fullarton Woods, Troon, during the first quarter, no breeding records were received. This decline was noted elsewhere in Scotland, with many Northern areas being forsaken and notable decreases witnessed in Southern regions such as Dumfries and Galloway.
In Ayrshire, 1985 saw a brief improvement, with a pair reported as probably breeding in North Ayrshire and other singles in suitable sites at Auchinleck estate, Barskimming, Kelburn and Hunterston. Interestingly, a single still hung on at South Wood, Troon in the early part of the year. Although 1986 saw a calling bird at its usual haunt in Kelburn during May, there were only 3 other reports of singles. Two more records of singles followed in 1987 and another two in 1988 when they were reported to have bred at Montgreenan. 1989 produced a further brace of records, with one of them at Tarfessock in April, providing a clue to the route which some of these birds follow to move into Ayrshire.
The 1990s began with two further records of singles, but no breeding reported. However, 1991 showed a slight improvement, with two calling birds in suitable habitat in North Ayrshire during May. It was said to have bred at a North Ayrshire location in 1992, and this was followed by an intriguing record during August when a sickly juvenile was collected by a golfer at Troon and taken to Hessilhead Wildlife Centre. Had it been reared locally? The woodland nearby at South Wood is certainly suitable, and Green Woodpecker has a surprising ability to avoid detection. A continued improvement was evident in 1993 when up to 4 territories were noted, 2 pairs reported to have bred, in North and Central Ayrshire. Four other records of singles occurred during the year.
Just when it seemed like a pattern of territory re-occupation was beginning to happen, 1994 produced only 3 records of singles. 1995 was little different with a pair at Brownmuir, and a single at Cuffhill on two dates. A pair was back at an old haunt, Portencross, throughout 1996, but only 3 other birds were reported from 2 locations. The Portencross pair were again present on 9th July 1997, and two other records of singles that year included a bird at South Wood. Just one midsummer record of a single bird at Kelburn in 1998 summed up the unpredictability of this species, while South Wood returned the only record for 1999 during March. This bird was present again during midsummer in 2000 – the sole report for that year. 2001 saw single birds back at Fullarton Woods in January, with others at Kilkerran and Irvine during May. April 2002 produced records of singles at Fullarton Woods and Portencross, but no more breeding records. Three further reports of lone individuals came in 2003 from Largs, Hunterston and Auchendrane, but 2004 was the first year in recent times when none were observed within the county.
It looked like we were about to lose the species from Ayrshire, with only single Spring records from 2005 and 2006. Three records of Spring singles in 2007 was followed by 2 from North Ayrshire in 2008 and 2 more in 2009. Three reports of individuals in 2010 involved 2 from formerly occupied areas, 2011 produced only 2 records of singles, and 2012 saw the addition of just 3 more solitary birds. No birds were reported once more in 2013, only one in 2014, and none in 2015. Apparently the potential colonisation of the 1970s and 1980s had stalled, and the bird’s range was shrinking Southwards.
Juvenile Green Woodpecker, Straiton, Ayrshire. August 2017 (A.Hogg)
On 15th April 2016 a single bird was heard calling from the oak woodland at Craigencallie, Straiton. No sooner had it flown across the river and landed on a tree when it was chased off and caught by a female Sparrowhawk – a somewhat unfortunate re-emergence of the species within the county. There were only two further reports of single birds during that year. However, a check of the same woodland in early Spring 2017 revealed the presence of a pair. Repeated visits to the site revealed their continued presence there through May, June and July, by which time they had become considerably less vocal and often difficult to see. A likely nest-hole was discovered in mid-June and a visit on 31 July produced clear evidence that they had been successful, with 3 fledged juveniles noisily flying around. This is the first proven breeding record for 24 years, although it’s quite possible that breeding has gone undetected elsewhere in Ayrshire during this time.
However, in 2017, there were also 3 more records of single birds, raising the possibility that the species may be embarking on another push Northwards. This can be both a flamboyant and a frustrating species to watch, depending on the time of year but, for anyone visiting an area of suitable woodland in Ayrshire in the Spring, it would be worth listening for that “yaffle” call.
“Well, nobody looks at pipits!!” An often repeated statement from birders and non-birders alike. It’s perhaps understandable, since this little group of birds is maybe not the most glamorous. Well, maybe I can persuade you to have a look at some of these “little brown jobs” since there’s a lot more to them than meets the eye (at least, in the first instance!).
Ayrshire currently has 5 species of pipit on its list, with the large Richard’s Pipit having been recorded on only a single occasion so far. Of the four other species, Water Pipit is undoubtedly the scarcest, being a winter visitor from the European mainland. Rock Pipit is the nearest to an omni-present species, with some migration taking place during Spring and Autumn, when some other races may be involved. Tree Pipit is a Summer visitor and is usually present as a breeding bird in our upland forestry areas between mid April and September. The one that most of us will be acquainted with is Meadow Pipit although it, too, is a migrant, with only a few choosing to overwinter.
So, let’s take two of these closely allied species to begin with and see how we can identify them. Water Pipit and Rock Pipit used to be considered as the same species, but a recent “split” resulted in a separation – and one which seemed sensible to those of us who had suggested some time previously that their habitat choices, for one thing, were substantially different. If we take Water Pipit to begin with, it’s important to know when to look for it in Ayrshire. Since the first record in 1970, the bird has been well recorded within the county, and Ayrshire has proved to be one of the best counties in Scotland in which to see one. It’s primarily a Winter visitor from its high montane breeding grounds in West and Central Europe and, while many will head South into areas like South Spain and the Balearics to overwinter, some head North-west to spend the Winter months in the UK.
Water Pipit, Girvan, December 2009
Water Pipit, Maidens, December 2010
It was initially thought to be a bird which could be found in habitats like watercress beds and sewage farms in the Southern counties of England, with any suggestion of shoreline feeding on seaweed accumulations being dismissed. This habitat has, however, turned out to be one which is frequently used by Water Pipits in our part of the world (Scotland is not blessed with a lot of Watercress beds!). Very often these seaweed piles lie in sheltered bays or at the mouths of burns and rivers e.g. at Maidens and Doonfoot. Most of our birds arrive from the end of October and depart for their breeding grounds in late March-early April. During March they will undergo a body moult in which their appearance as a “different” species will become much more apparent.
Rock Pipit, Troon, January 2009
Water Pipit, Seamill 2010
When they arrive in the late Autumn, you might be forgiven for thinking that the bird in front of you is just a bright-looking Rock Pipit. However, your attention might just be drawn initially to its unusual , flighty behaviour – quite different from most Rock Pipits, which normally allow fairly close approach. Secondly, once you’ve caught up with it, you’ll be aware of a bird which is largely white below and brown above; a contrast to most of the nearby Rock Pipits which are pretty drab with their olive-tinged grey/brown upper-parts and dull underparts, often with heavy, dark streaking in this area.
A closer look at the bird will pick out one or two other notable plumage features:- a clear white supercilium, two white wing-bars on the tips of median and greater wing coverts, a white or off-white throat, and white outer tail feathers, the latter feature showing well as the bird flies away from you again! The dark streaking on the breast can appear much finer than that of Rock Pipit, and is largely concentrated on the upper breast, thinning out on to the belly and becoming much more diffuse on the flanks. A brownish/grey back will show some dark streaking, but the rump is often a richer, warmer brown colour. The bill, which is usually more slender than that of a Rock Pipit, has a largely yellow base to the lower mandible and the legs are dark, often showing reddish brown (a useful feature if you’re unsure about a greyish Meadow Pipit perhaps?). With a lot of these features, it’s well worth remembering that light conditions will play a big part in what you perceive to be colours and tones.
Water Pipit, Pow Burn, December 2016
Most birds are fairly active feeders, and a good time to look for them is at high tide, when the seaweed will often be disturbed by waves lapping against it, perhaps unsettling invertebrate life within it. Above all else though, patience is the key, since most birds which take off and appear to fly for miles along the beach in front of you, will often return to exactly the same spot they were feeding in a few minutes beforehand.
Water Pipit, Doonfoot, December 2016
By mid March, if your overwintering bird is still around, you’ll start to see a few changes in its plumage. It starts to look quite scruffy and gradually takes on a pale greyish appearance. The white supercilium is still there, but now it’s set against a pale grey crown and ear coverts. The upper-parts become mostly pale grey and the dark breast streaking almost totally disappears, leaving plain white underparts with a pinkish breast. The top part of the head pattern can vaguely resemble a Northern Wheatear at times. It should be pointed out, however, that many birds will depart before they look like what most field guides show as typical breeding plumage.
Water Pipit, Maidens, late March 2007
Other races of Water Pipit have been recorded within the UK, and it’s possible that the closely allied Buff-bellied Pipit could be a future addition to the Ayrshire list. That would require more folk to look harder at pipits though… so, how about it?
And you thought it couldn’t get any worse! Well, truthfully, it could. Although we now know that Water Pipits can be identified with a wee bit of care, identification of Rock Pipits is not so straightforward as many of the field guides suggest. An example of this can be seen in the two photos below – both show Rock Pipits, but at different times of year:-
Rock Pipit, Doonfoot, November 2013
Rock Pipit, Troon, July 2012
Both birds show many differences in plumage, and it’s hard to believe that it’s the same species you’re looking at! However, the two photos illustrate just how confusing it can be to identify what many people would regard as a “dull” bird (and not worth a second look?). So, how have we arrived at the point where we’re almost considering taking up stamp collecting? Well, the two birds look similar in size and structure: they share the same habitat: and they give the same call (OK, I know that’s cheating since you can’t hear a still photograph). The next step is to look at the plumages. The November bird looks really crisp, with a lovely olive-green cast to its upperparts, and fresh upper wing coverts with their dark centres and whitish tips. Sometime during the early autumn it would have undergone a post-breeding moult and is in excellent condition.
The July bird, by contrast, looks like it’s been dragged through a hedge backwards! Its worn, grey plumage shows little or none of the neatness of the November bird. The upperparts appear very plain and lack the greenish tinge of the other bird, while the upper wing coverts have all but vanished as a feature. Even the dark streaking on the breast looks worn and almost mottled in appearance. Well, it has just come to the end of the breeding season, and the plumage has obviously just lasted long enough. Time to moult!
Most of the Rock Pipits we have, locally, in Ayrshire tend to look like the November bird for much of the year and exhibit the following features:-
There are other plumage features but, bearing in mind that the rigours of the breeding season can alter the colour and tone of the plumage (and the timing of these changes varies from bird to bird), have a look at the two photos below:-
Bird A, Turnberry Point, 2010
Bird B, Maidens, 2011
See if you can guess the month in which the two photos were taken (click on the photos to expand to full size). Answers at the end of the article.
I guess I’d be giving my age away if I referred to Acker Bilk here. However, the point of this section is to highlight something which very few people notice during the Spring migration period i.e. many of the migrant Rock Pipits which occasionally gather on seaweed piles don’t look like our birds. Rock Pipits are migratory, although seldom forming large aggregations – a “flock” of 20+ would be notable. During March and April, around the time when many White Wagtails throng our shorelines, you’ll sometimes notice small numbers of odd-looking Rock Pipits. Just why are they odd-looking, I hear you ask? Have a look at the 2 photos below, and see what you think:-
Rock Pipit, Maidens, March 2011
Rock Pipit, Maidens, March 2011
Several features might strike the observer right away – the left hand bird is very pale, shows a clear, white supercilium, and has reasonably fresh upper wing coverts. The bird on the right is very grey, also has a clear white supercilium and also has fresh upper wing coverts. The right hand bird also shows a faint pinkish tinge (honest!) to its very white and poorly streaked underparts. To adapt a much used Star Trek phrase: “They’re Rock Pipits Jim, but not as we know them.”
Much has been said and written in recent years about “Scandinavian” Rock Pipits, and I suppose that some of our migrant birds fit with the descriptions given in various field guides for these birds. However, even specialised books dealing with pipits and wagtails fail to agree on basic identification features, moult timings and extent etc. Within the UK, there used to be at least 3 breeding races of Rock Pipit, all of which vary in plumage tones according to most sources. The so-called Scandinavian Rock Pipit is said to winter in the UK, but is also stated to be largely inseparable from our Rock Pipits at that period. Confused?? You’re not alone!
Most Scandinavian Rock Pipits are said not to assume much, or any, pinkish-ness on the breast in fresh, pre-breeding, Spring plumage – yet a few have been seen in Ayrshire which were quite obviously pink on an almost clear whitish breast. It was this feature, along with the clear white or whitish supecilium which caused some confusion among local birders in Ayrshire during the “discovery” years of the early 1970s when the first Water Pipits were being identified in the county. But, are these recent “odd-looking” birds Scandinavian Rock Pipits? To be honest, I’m not totally sure, and some may not be anything more than examples of what were formerly thought to be individual races (kleinschmidti from the Faroes, and Northern Isles, and meinertzhageni from the Outer Hebrides). Let me throw another idea into the ring here. What if Rock Pipits exhibit the same variation in plumage as Meadow Pipits? That’s nothing more than mere speculation, but I remain intrigued by these strangers which appear regularly along our shorelines in Spring.
No doubt, like so many other recent discoveries, work on DNA sequencing may hold the key to their true identities. One thing is certain – Rock Pipits are most certainly not dull!
Answer to earlier bird photo question: the bird on the left was one of a breeding pair at Turnberry lighthouse on 24th April. The right hand bird was photographed at Maidens on 12 November.

Some years ago – well, a considerable numbers of years ago – I decided to take part in a county-wide survey of Rooks which had been organised by the late Malcolm Castle. This wasn’t the first such survey which he’d organised, and it wasn’t going to be his last, but it seemed so delightfully simple that I chose one or two rookeries which I would then go out and try to count.
It certainly sounded simple and, typical of its organiser, the instructions were really straightforward. But, then, that’s the way surveys always look until you start on them! One major obstacle with my first large rookery at Kirkmichael was that many of the birds nested in the crowns of Scots Pine trees, rendering a totally accurate count almost impossible. However, a challenge like this was something to be tackled head-on, and, 4 hours later, I’d ploughed through just over 400 nests. One or two rookeries later, and I was starting to enjoy it, but it wasn’t until Malcolm had pulled all the results together that I saw the real purpose in doing such a series of counts.
That was 1975, and Rooks were doing well within Ayrshire. The survey was repeated in 1986, and it looked like the future was bright for the species. Moreover, the survey had provided all sorts of information for observers to get their teeth into e.g. rookery sizes, favoured nest-trees and overall distribution within Ayrshire. A further survey was arranged for 1996. Sadly, Malcolm didn’t live to see the final results written up, but Roger Hissett placed the results in the Ayrshire Bird report of 1997. These showed that the Rook was still faring reasonably well, despite substantial changes in the rural landscape.
In 2005 Kevin Waite took another slant on assessing the health of the Rook population in Ayrshire. His one-man survey drew on previous survey results, and looked at particular aspects such as urban growth, nest-tree species and site faithfulness. One urban area which seemed to have remained fairly stable was Maybole, perhaps due to the slow rate of urban expansion, and a mixed farming regime in the nearby countryside which appears to have shown relatively little change in the past 20 years.
Within the town itself, most of the nests have been built in Beech trees, but one or two outlying locations, which hold between 1-5 nests, can reveal the use of other tree species, the strangest perhaps being in a car park near the Town Hall where the nests in Birch trees could easily be mistaken for the Witches’ Broom infestation. The table below outlines the count results between 2001 and 2016, most counts usually having been carried out in mid-April, at a time when most nests would clearly show signs of occupation.
The 2001 count was almost certainly an under-count since, at the time, I was not aware of the full extent of the area covered by all the nests. However, since 2005, there has been an increase, and a period of stability, followed by a very slight decline. It’s difficult to be certain that this decline is something to be concerned about – many Rookeries in nearby rural areas have flourished, fragmented, declined and, in some cases, disappeared during the past 15-20 years. The reasons for these fluctuations aren’t entirely clear (there’s a job here for some keen young field-worker!), but they will almost certainly reflect the relative abundance of food locally, to some extent. Other factors may include, for example, the increasing trend for Ravens to nest at the periphery of some Rookeries since, by nesting earlier than Rooks, they can exploit the availability of a nearby food supply.
There appears to be little problem with human interference in Maybole at present, so food availability perhaps linked to a changing climate pattern could emerge as important issues. Either way, Maybole’s Rooks continue to fare reasonably well within their urban environment. This kind of survey is easily carried out, and will not just provide a picture of what’s happening to a species over a period of time, but will also throw up a range of questions associated with these results e.g What are the main factors driving the population changes? This, then, can become the basis for a related survey which can use the nesting figures as a starting point. Is anyone up for it?

When the American Golden Plover turned up at Maidens on 17th October, I was confronted by that thorny problem of having to write a description. There are those among us who, for good reasons or not, prefer not to bother, in the hope that:
Maybe it’s down to an era in which I cut my teeth in birding, but I have always been a fan of the written word when it comes to descriptions, throwing in the odd sketch where appropriate. Nowadays, the importance of the field sketch has, to large extent, been negated by the advent of digital cameras (although I still think sketches are useful). Not everyone has a camera – nor can everyone turn in a Killian Mullarney masterpiece – but everyone can write a description of what they saw.
Leaving it to others, or going down the “mass observer” route is, of course, a matter for the individual, but I suspect that there are a few observers out there who have found a really rare bird and get more than a little irritated when the record doesn’t appear in the local or national archive. And, that’s partly where the problem lies. All such records of what are, after all, a tiny minority of what’s seen every year in the UK, require a description in order to be accepted as documented evidence within an area’s avifauna. To effect this, you must submit to the judgement of a panel of so-called experts. Not everyone likes this idea, comments ranging from “I know fine how to identify a bl*o*y American Golden Plover” to “Who are this bunch of eejits anyway?” All well and good, but records (if submitted) have to assessed somehow.
All right, if you don’t like the idea of an assessment panel, why not become an active member of it? “Oh, I’ve got too much to do (washing my hair that week, and similar excuses).” Nonetheless, record assessment panels have to draw conclusions on what evidence is submitted and, as far as is possible, they do so in a democratic fashion. Conspiracy theorists will no doubt harbour their own thoughts on why records are rejected, and the system for assessment will always contain a certain amount of subjectivity, but it is about as fair as is possible.
Anyway, I know that some observers baulk at the notion of writing up descriptions: indeed some are not at all confident in doing it. That really shouldn’t stand in the way of an honest submission though. So, what should you include? Let’s take the Maidens American Golden Plover as an example.
I first caught sight of the bird as it circled slowly, with a flock of European Golden Plovers, at Maidens on the morning of 17th October. As the flock wheeled around in bright sunlight, there was one bird which appeared slightly slimmer and longer winged compared to the others. Moreover, it looked like it had plain grey underwings, compared to the gleaming white underwings of the “Goldies.” I entertained the idea at this point that this could be an American Golden Plover, but this kind of sighting would clearly be insufficient for submission as such – it could just be a “small” European Golden Plover, and bright sunlight does amazing things to your perception of underwing tones! After 20 frustrating minutes, the first group of 10 birds landed and I managed to get a good look at the “suspect” bird.
A few seconds later and it was airborne again, not re-appearing again that morning. However, and a lot of what follows comes down to species familiarity, the main features had been clearly seen – enough to be sure of its identification. So, what were the key features? Briefly, they included the following:
Additional features which could be added from the extensive flight views would have included a weak whitish wing bar and pale, grey axillaries.
It might have been useful to have heard it call, but there was sufficient here to scribble down a few notes (or, as I’ve been doing for years, put these details on to my voice recorder. This has the advantage of not having to take your eyes off the bird as you note the details).
What you decide to do about writing up a description is up to you, but simplicity can often be the key. There is no need to over-embellish the text since the main thing is to set out clearly just why you thought it was a certain species. After writing up your description, it’s a good idea to hold on to it until you’re sure the bird has gone from the area. In this case, one, fairly useful piece of additional information was obtained – the call. This usually stands out clearly from European Golden Plover: a short, shrill, whistled “kleeee – ih” with the second part just audible (Transcriptions of calls can be a nightmare for some, but still helpful if you can put them on paper).
Photographs of the bird were obtained on 1st and 3rd November – all adding to the complete picture. In addition, many observers were lucky enough to see this bird before it departed, which can be helpful for corroboration. So, whatever your attitude is to writing up descriptions, can I encourage you to give it some thought – if nothing else, it can make the local recorder’s life a lot easier!
