A blast from the past: Sooty Tern, Ditchford Gravel Pits, May 1980

Pulling up outside John and Ruth Ward’s home in Irchester I found it difficult to decide just how I would feel about seeing it again – this time dead. I refer of course to Northamptonshire’s one and only Sooty Tern and more than thirty-two years had passed since I had last seen this bird, alive, at nearby Ditchford Gravel Pits, in May 1980. So, déjà vu or nostalgia? Undoubtedly both.

If I had been wearing a hat I would have removed it as I stood in reverie before the inornate glass case which is, for the foreseeable future, this bird’s resting place and which takes pride of place on a unit in John & Ruth’s dining room. Expert taxidermy has immortalised the bird’s appearance but sadly not its character following its demise in captivity in November 1980 and the events leading up to that date were unusual, to say the least …

During a routine evening visit to his local patch, the main lake at Ditchford Gravel Pits, on 29th May 1980, John (‘Jake’) Ward was astonished to see a Sooty Tern approaching along the Nene valley from the east. Swiftly joined by the late Dave Young and his wife, Lorraine, who were birding in the vicinity, John watched it flying around briefly before it went to roost on one of the islands in the lake and news of the bird’s presence was broadcast later that evening.

A group of excited observers – the majority local – had assembled before first light the following morning but as the sun rose the tern was, initially, nowhere to be seen. Then someone spotted it on the back edge of an island. It was weak, unable to fly and, distressingly, attracting the attention of a marauding Carrion Crow. On the point of becoming a crow’s breakfast, a swift decision was made to rescue it and, without further ado, as I recall, Jon Eames braved the uncharted depths of the lake and waded out to save it from certain death.

After a 05.45 phone call to the late Cliff Christie, cold and emaciated, it was then taken by motorcade (minus outriders) to Cliff’s bird rehabilitation centre in Middleton Cheney in south Northants. Cliff had built a well-deserved reputation for rehabilitating sick and injured birds and, over the following days and weeks, his expert nursing, along with a diet of cod liver oil and whitebait, had the tern back in good health and ready to be released back into ‘the wild’.

During this period the bird drew many admirers, some travelling from mainland Europe, and it became a bit of a celebrity, the national press and TV news covering its remarkable story of survival. It even made international headlines with the Cape Town Argus devoting a column to it on one occasion.

Amid the publicity, however, a more serious story began to unfold as attempts to repatriate it were repeatedly thwarted by international bureaucracy. It appeared to be of the nominate race fuscata, which is found in the Caribbean and Atlantic and the plan was to fly it to east coast America to release it in either Jamaica or Florida. Because of its now captive status an export licence was obtained from the UK government and, with the appropriate documentation in order – plus the support of Captain John Philips, a British Airways pilot – BA kindly offered to transport it free of charge. So far, so good but the tern’s luck was soon to run out as the plan fell foul of the USA’s strict quarantine laws and rumour had it that it would be killed upon arrival by Jamaican authorities if it was flown directly to that country. It appears that several attempts made to ship it to other countries in the region were also opposed, despite the best efforts of Jenny Blenkinsop, a Birmingham-based BA customer services officer who had taken up the case and championed the bird’s repatriation bid.

Unfortunately the Sooty Tern appeared destined to stay in the UK and it died in captivity on 8th November 1980 after a period in quarantine, with its ‘owner’ still hopeful of successful repatriation. But that was not the end of the story.

Cliff preserved the body before handing it to Mark Winston-Smith, a taxidermist in Snitterfield near Stratford-upon-Avon, to mount it. Encased in glass, the tern remained in the Christie family after Cliff’s death in 2003 and his wife, Joyce’s death in 2011. The specimen was then apparently discovered for sale in Banbury, believed to be as a result of a house clearance (although the details are not clear) and subsequently went into private ownership in Staffordshire. The owner then decided to sell it and contacted the BTO for first refusal. In November, John Marchant from the BTO emailed a handful of birders in Northants (including myself and John & Ruth) to elicit interest in the purchase, a deal was done and the rest – as they say – is history.

It is only fitting that the Sooty Tern has now come back to the finder some thirty-two years after the event. John and Ruth have agreed to pass the specimen to the BTO upon their own demise, which we hope will not be any time soon, of course, and they welcome anyone who wants to see the bird to their home in Irchester so please feel free to contact them.

The Week in Focus: 22nd to 28th December 2012

Another mild and largely wet week with few new discoveries, despite it being a ‘holiday week’ with presumably more birders taking to the field. Single Shelducks were seen at Blatherwycke Lake and at Deene Lake on 23rd while other duck numbers began to build, with the maximum count of Goldeneye reaching twenty-three at Ditchford GP on 23rd. Goosanders were recorded at Abington Park Lake, Clifford Hill GP, Ditchford GP, Pitsford Res, Stanford Res and Stortons GP with a maximum of six at the latter site on 26th.  Pitsford Res was the only site where Smew were recorded this week with four or five at the dam end on 22nd, dwindling to a drake and one or two ‘redheads’ by 27th and a single ‘redhead’ by 28th. A drake Ruddy Duck was at the same locality on 26th. Last week’s first-winter drake Scaup was still at Ditchford GP on 23rd.

At Pitsford Res the Great White Egret remained throughout the week, favouring the flooded marsh at the junction of Hannington Road and Walgrave Road, just outside Holcot and the Slavonian Grebe remained halfway between the dam and the causeway all week.

Approximately two hundred Golden Plovers were near Oundle on 23rd but the only other wader of note was a Redshank at Pitsford Res on 27th and 28th with the gull roost at the latter site holding an adult and a first-winter Mediterranean Gull plus a first-winter Yellow-legged Gull on 22nd, the two first-winter gulls both being present there again on 24th. On 23rd and 24th nearby Hanging Houghton played host to a Jackdaw showing characteristics of the southern Scandinavian race monedula, ‘Nordic Jackdaw’, which is a scarce winter visitor to the county.

A Cetti’s Warbler was found at Stanford Res on 27th – an unusual record for this site – while a pair of presumed Central European Blackcaps continued to visit a Northampton garden during the week and another visited a garden in Potterspury on 22nd.

A male Stonechat was found at Blueberry Farm, Maidwell on 28th.  In comparison to last week, Waxwings were in relatively short supply, the regularly appearing (although frequently elusive) birds in Brackley, Chelveston, Polebrook and Sywell all having moved on. Just a handful of fleeting visits were made by five to Holcot on 23rd, one to

Irthlingborough on 25th with four in the Brampton Valley below Brixworth and eight to ten at Morrisons Supermarket, Kettering Road, Northampton on the same date. On 28th eleven were in a garden at Hanging Houghton and nine were on Newport Pagnell Road, Wootton Fields, Northampton. Bramblings continued to be seen throughout the week at Harrington AF, where there was a maximum of eight on 26th, Kelmarsh with a maximum of four on the same date, Hanging Houghton where there was one on 23rd and two on 28th and at Pitsford Res with singles on 24th and 26th.

The Week in Focus: 15th to 21st December 2012

In stark contrast to the previous week, the last seven days saw the return of relatively mild, wet and windy conditions and rising floodwater. The adult Dark-bellied Brent Goose remained at Clifford Hill GP until at least 17th and the same site hosted this week’s maximum count of Goosanders with 13 there on 16th while 3 were at Pitsford

 Res on 17th and 8 at Daventry CP on 21st. The only Smew during the period were a ‘redhead’ at Pitsford Res on 17th, two ‘redheads’ at Ditchford GP on 18th and the same number at Ravensthorpe Res the following day. A first-winter Scaup was again at Ditchford GP on 18th.

The Pitsford Res/Holcot Great White Egret remained throughout the week and a Slavonian Grebe  was found there on 18th and, in the raptor camp, a Peregrine was on pylons by the fishing lake at Ditchford GP on 16th, another was at Stortons GP on 17th and a Merlin was seen at Harrington AF the next day.

Waders were thin on the ground as is so often the case at this time of the year and, apart from small flocks of approximately fifty Golden Plovers at Clifford Hill GP on 16th and sixty at Ditchford GP on 18th, the only one of note was a Redshank at Clifford Hill GP on the former date. The only Short-eared Owl reported was one at Harrington AF on 17th but more unusual was a flock of nine Ring-necked Parakeets which flew over Stoke Bruerne the following day. Ditchford GP also held three Chiffchaffs on 18th and further singles were at Clifford Hill GP on 16th and Pitsford Res on 17th while a pair of Central European Blackcaps was in a Northampton garden on 15th with another in a different Northampton garden the next day.

Upholding their recent winter scarcity, two Stonechats were found at Ditchford GP on 18th. Waxwings continued to be reported throughout the week with singles at Polebrook, Syresham and Woodford Halse on 15th and at Byfield on 21st and twenty-five in Brackley

on 15th. Thirteen were in Woodford Halse the following day, up to twelve remained around Chelveston on until 21st, approximately twenty were in Finedon on 18th and, on 19th, at least thirty were in Brackley. Up to a dozen visited gardens in Sywell on 19th and 20th

while, during the same two days, up to thirty-six were feeding in gardens and showing well on TV aerials in Polebrook. Two visited Pitsford Res on 21st and up to four Bramblings were also at there with ten at Harrington AF on 17th.

The Week in Focus: 8th to 14th December 2012

The continuing cold snap this week saw the further arrival of more traditional winter fare as well as the discovery of a Dark-bellied Brent Goose at Clifford Hill GP on 13th. The drake Scaup at Pitsford Res was still present there on 12th and  the number of Smew at

there on 12th. Smaller number were found at Daventry Res (nine), Stortons GP (five) and Pitsford Res (two).

The Summer Leys Bittern showed again on 8th and another was found at Stanwick GP on 13th while the Pitsford Great White Egret was seen again on 9th and 13th and a Black-necked Grebe – perhaps the Pitsford individual – was discovered at Sywell CP on the latter date.

In the absence of any serious contenders, a male Hen Harrier hunting briefly over setaside at Blueberry Farm, Maidwell on 10th scooped the title ‘Raptor of the Week’ while an adult Mediterranean Gull in the roost at Pitsford Res on the same date was similarly the only scarce gull reported. Also on 10th, two Chiffchaffs were found in the grounds of St Andrews Hospital, Northampton and the male Central European Blackcap was still feeding on crab apples in a Northampton garden until at least 13th. Waxwing numbers continued to build with the Kettering flock at Sainsburys supermarket car-park peaking at fifty on 8th and dropping to just twenty-two on 9th before disappearing completely the

toward Wootton and approximately twenty were by the A45, close to Northampton Garden Centre, on 12th with sixteen at Chelveston on the same date. Seven remained in Chelveston on 13th when approximately 35 were located in Wootton and one flew over Pitsford Res on 14th.

Single-figure counts of Bramblings were made throughout the week at Hanging Houghton, Kelmarsh and Pitsford Res with a maximum of six at Harrington AF on 10th.

The Week in Focus: 1st to 7th December 2012

This is the first in a new series of weekly reports which picks out the highlights from the past seven days – in this case 1st-7th December.

This month usually sees the beginning of a build up of scarcer wintering wildfowl but eight Dark-bellied Brent Geese which flew over Haselbech on 2nd was a great, unexpected record for a species which normally only occurs as singles in late autumn. A first-winter drake Scaup was discovered on the fishing lake at Ditchford GP on the same date, being joined by another there on 5th while an adult drake was seen off the dam at Pitsford Res the following day. Three ‘redhead’ Smew were found on the ‘small side’ at Ravensthorpe Res on 1st and a drake had joined them by 7th, while the highest count of the more common Goosander was eighteen at the now well established urban wintering site of Abington Park Lake, Northampton on 1st.

A Bittern was found at Summer Leys on 2nd and last month’s Great White Egret continued to show sporadically at Pitsford Res (and on adjacent floodwater at Holcot) throughout the week. The long-staying Black-necked Grebe, present since September, remained in the vicinity of the yacht club at Pitsford Res until at least 3rd and a ‘ringtail’

Hen Harrier was watched hunting south of Weston on 1st but subsequent searches failed to relocate it. Other scarce raptors included single Merlins at Blueberry Farm, Maidwell on 4th and at Fineshade Wood and near Firmyn Woods CP the following day, while two Peregrines were at Fineshade Wood on 5th with two more at Ditchford GP on the same date. A count of 17 Common Snipe at Ditchford GP on 2nd was noteworthy when a single Redshank was also present there.

A first-winter Mediterranean Gull visited Pitsford Res roost on 4th and an adult was at Ravensthorpe Res the following day, while an adult Caspian Gull was found at Sidegate Landfill an 5th and a third-winter roosted at Pitsford Res on 6th. The only Short-eared

Owl of the week was one at Harrington AF on 6th and, braving the falling temperatures, a Chiffchaff was seen at Ravensthorpe Res on 5th and 7th and a male Central European Blackcap was feeding on crab apples in a Northampton garden throughout the week while a Stonechat – locally scarce this winter – was at Ditchford GP on 2nd.

As the week drew to a close, however, Waxwings began to move in in force. Twos were seen at Hanging Houghton and Sywell on 1st and at Pitsford Res on 3rd, with one at the latter site on 4th when at least fourteen were found in Corby. Five were in Daventry on 5th with, the next day, four or five at Byfield and one at Daventry CP but the week ended with thirty-one at Oundle, approximately thirty in Kettering (at Sainsburys supermarket) and ten in Wellingborough at Appleby Lodge Farm.

A Hawfinch was reported from Firmyn Woods CP on 2nd and, apart from one at Hanging Houghton on 1st, up to ten Bramblings were visiting Harrington AF to feed on wild bird food throughout the week.

Breakaway Blackcaps

Blackcaps are not an uncommon sight in Britain during the winter months nowadays. We have a ‘healthy’ wintering population of around 3,000 individuals which compares with a summer population estimate of 932,000 pairs (Birdlife International, 2004). Numbers wintering in the UK have increased considerably since the 1960s and it would seem likely that the above number is an old and conservative estimate so if anyone has an up-to-date figure I would be pleased to receive it.

Numbers wintering in Northants appear to have risen and averaged higher since the early 1990s, although this may reflect better observer coverage and communication.

From the early 1990s numbers are approximate, based largely on localities and estimates rather than specific individuals. Source: Northamptonshire Bird Report 1969-2010.

Ringing data have established that UK winterers are from a breeding population in central Europe and, while most Blackcaps from this area head south-west in autumn to winter in Spain and northern Africa, some head north-west to the UK. The driver for this is not clear but milder winters and an abundance of ‘artificial’ food (i.e. winter bird feed provided by man) have been cited as the likely reasons. The latter of the two factors appears to be the subject of debate as many observations on wintering Blackcaps point to their feeding primarily on natural food sources such as berries and insect larvae when these are available.

Male Blackcap, Northampton, December 2012 (Dave Warner)
Male Blackcap, Northampton, December 2012 (Dave Warner)

Dave Warner’s excellent portrait of a male in his Northampton garden last weekend illustrates this point perfectly with the principal choice of food, Dave suggests, being an abundant supply of crab apples. That said, it seems logical to assume that ‘artificial’ food may at least act as a regular supplement or backup in the absence of natural foods, thus helping maintain the wintering population.

What is clear, however, is that our wintering Blackcaps are very different from those which breed here in summer. Having a shorter distance to fly to their breeding area in spring means they arrive back before the Spanish winterers and therefore only have each other to mate with, effectively becoming reproductively isolated from the Spanish birds.  So now there are morphological differences emerging. This population, in the space of little more than 50 years, has produced birds with rounder wings (as they don’t need to migrate so far) narrower and longer bills (supposedly for taking advantage of ‘artificial’ foods) and browner mantles and bills. A kind of ‘catalytic evolution.’ How far will it go? Full speciation?

So next time you come across a Blackcap in Britain in winter it’s worth remembering that it’s not just any Blackcap, it’s likely to be a breakaway Blackcap – an activist, a rebel, a pioneer and, although a potential champion of speciation, it may only ever become genetically distinct to a racial level, so don’t hold your breath for an ‘armchair tick’ any time soon …

Ditchford Scaup

I found this first-winter drake Scaup on the Fishing Lake at Ditchford Gravel Pits this morning. It was still present at midday. Difficult to see on the video below, surprisingly it was already showing a greenish sheen to the otherwise brown head and adult vermiculated grey scapulars were just beginning to appear.

Scaup is a scarce visitor to Northants with about half a dozen records per year, the vast majority of which relate to single birds although small flocks have occasionally occurred in the past.
