THORNE MOORS BIRD REPORT 2010
Compiled by Martin Limbert and Bryan P. Wainwright
1. Recording area. For bird documentation, the Thorne Moors recording area is deliberately interpreted somewhat loosely. It comprises the whole of the peatland, contiguous unfarmed areas, the Thorne Colliery curtilage, and peripheral farmland and drains. The limit to the north is defined as the line of the old Axholme Joint Railway. Otherwise, a field width or so is a practical rule-ofthumb.
2. Place-names. In broad terms, the name Thorne Moors is used to embrace both the peatland and other areas under study. The surviving peat is divided by parish limits, the parish names being Thorne Waste, Snaith & Cowick Moor, Rawcliffe Moor, Goole Moor and Crowle Moor. Thorne Waste (except now the Yorkshire Triangle) lies in South Yorkshire, and the other parishes lie in East Yorkshire, except Crowle Moor and the Yorkshire Triangle, which are in North Lincolnshire. That part of Goole Moor situated north of Rawcliffe Moor is designated as ‘Northern Goole Moor’ for recording purposes. Within the parish framework, numerous place-names are employed for bird recording. Virtually all these names were included on the place-names map issued with the Thorne Moors Vertebrates Report 2005. This is now superseded by a place-names map on the website of the Thorne & Hatfield Moors Conservation Forum.

4. Descriptions. For nationally rare avian taxa, descriptions and visual evidence should be made available in accordance with the requirements of the British Birds Rarities Committee. At county level, material should be prepared in compliance with the lists issued by the Yorkshire Naturalists’ Union Birds Section Adjudication Panel or the Lincolnshire Bird Club, as appropriate. Advice can be made available upon request.
5. Rare breeding birds. In addition to Natural England, records of rare breeding birds are made available to the county organizations, and via them to the Rare Breeding Birds Panel. Records may also be accessed by bona fide specialist study groups.
6. Daily Counts. In the species accounts that follow, there may be references to “daily counts” and “counts”. It is emphasized that these are not full site counts, but counts made by an individual observer or group on a particular date. It is possible to have more than one count on a single date, when the highest will be used if they cannot be united. The recording area is very large, and site totals are difficult to establish with certainty, except for the scarcer species. However, for some wetland birds, it is possible to visit the most likely places to count these species, thus attaining a relatively accurate moorland total for them. It is acknowledged that such reported daily counts may sometimes be regarded as vague, but they are broadly comparable over a period of years.
7. Recording in 2010. During the year, 149 species of bird, and perhaps two additional races, were acceptably reported from Thorne Moors, as defined. Many of the records were received via the Thorne Moors bird blog (www.birdingsiteguide.com), although a significant number still arrived as paper records. All formats are welcomed.
Two new species were reported in 2010, a Black Swan on 17th April and an Egyptian Goose on 7th August. In addition, there were several site rarities, including Barnacle Goose, Garganey, Little Egret, Red Kite, Golden Eagle (awol), Osprey, Red-footed Falcon, Spotted Crake, Common Crane, Mediterranean Gull, Glaucous Gull, Great Grey Shrike, Waxwing, Common Redpoll and Snow Bunting.
As breeding species, Black-necked Grebe and European Stonechat were notable. So too were 48 European Nightjar territories and 28 male Grasshopper Warblers. Conversely, only a solitary male Common Nightingale was reported; this bird was regarded as unpaired and only heard in the first half of May.
Record counts were obtained for Greylag Goose, Gadwall, Tufted Duck, Goosander, Marsh Harrier, Hobby, Common Crane, Yellow-legged Gull, Common Chaffinch and Linnet. However, counts of some additional species were not without significance, as varied as Pink-footed Goose, Woodcock, Stock Dove and Willow Tit.
Mute Swan Cygnus olor. In April, two adults were at Will Pits Scrape from 9th-10th, with singles on 17th/26th at flooded workings on Goole Moor.
Black Swan Cygnus atratus. One at flooded workings on Goole Moor on 17th April, first with a Mute Swan and later with eight Whooper Swans (BS, RJS). A new species for Thorne Moors.
Whooper Swan Cygnus cygnus. All records were from flooded workings, especially those north of Fisons’ Road. The first were four on 26th January. In April, there were 26 on 4th and eight on 17th. In the later months, there were October records on 17th (eight flew off east) and 20th (11). On 7th November, five+ flew off east, with three (same?) overhead later). Recorded later that month on 20th (two south) and 23rd (three north).
Pink-footed Goose Anser brachyrhynchus. No records until 27 on 16th September. Other September records were obtained on 18th (38 west), 22nd (50+) and 26th (20). There were some large counts in October, with totals in excess of 300 being 1000+ on 2nd/7th/9th, and c.2500 on the northern part of the moors on 24th. Also, on 14th October there were groups in flight and grounded of c.500, c.600 and c.700, total number uncertain, therefore 700+. Counts in November exceeded 150 on 5th (c.200), 7th (c.300) and 550+ on an unrecorded date. The records marginally extended into December, with four on 3rd.
One purportedly feral Pink-foot was present with Greylags on 18th/20th September.
Greylag Goose Anser anser. In January, there were c.100 on 12th and 44 on 31st. The only February record involved two on 20th. The March counts occasionally reached 14, though with c.40 on 23rd. The highest totals in April were 18+ on 24th, 31 on 26th and 16 next day, with those on 26th including one white bird. The May maximum was 15, including three adults and two broods (five and four) at Will Pits Scrape. Counts in June-July did not exceed five (on 11th June). August counts reached 34 on 2nd/10th, then from later in the month until early October, counts – often from Will Pits Scrape – were much larger. They occasionally reached up to 500+ (on 28th August and 16th September). One thousand+, a moorland record, were estimated on 2nd October, with c.500 on 9th, decreasing to c.200 on 17th and c.70 on 19th. These gatherings sometimes included one white and three partly white birds. The November maximum was a mere six, on 7th, and there were no December records.
Canada Goose Branta canadensis. The first were 17 on 20th February, with four on 1st March. Also recorded during 17th-27th April, maximum five on the first date, plus two on 5th May. In addition, there was one on 26th September and six on 2nd October.
Barnacle Goose Branta leucopsis. On 9th October, four were present with Pink-feet on flooded workings near Will Pits. They flew off north-west (WHP).
Egyptian Goose Alopochen aegyptiaca. On 7th August, an adult was with 14 Greylags at the flooded workings north of Fisons’ Road (WHP). A new species for Thorne Moors.
Common Shelduck Tadorna tadorna. The first were singles on 1st/23rd March, with records of one-two in April, plus eight on 23rd. During May-July there were occasional singles, and two on 18th June. The only August record was 10 juveniles on 30th. There were September records on 5th (one), 6th (nine) and 20th (one). The only subsequent record was 11 on 20th November.
Eurasian Wigeon Anas penelope. Noted in the early months on 28th January (three), 20th February (three), 2nd March (nine), 10th April (three) and 26th April (one). An eclipse male was present on 6th September. There were five on 2nd October, followed by 14+ on 7th. Encountered in November on 7th (four) and 20th (11+).
Gadwall Anas strepera. Up to four in January/March, but with a greater presence in April, most notably 17 on 2nd, 15+ on 24th and 31 (with young) on 26th, the latter a moorland record. Counts May-August reached two occasionally, but in August females were seen at the flooded workings with five fledged young on 2nd and six young on 10th, presumably therefore separate broods.
Eurasian Teal Anas crecca. Monthly maxima were February four, March 70+, April 87, May two, June c.60, July 124, August 180+, September 300+, October 300+, November c.350 (on 7th) and December c.30. Breeding was proved at Will Pits Scrape (a female with a brood of three on 17th May) and Goole Moor (a pair with a brood of four on 12th May). Young birds were also seen on 2nd August.
Mallard Anas platyrhynchos. Monthly maxima were January c.300, February 150+, March c.100, April 30+, May eight, June c.30, July 12, August 182, September 150+, October c.150, November 18 and December 31. A predated nest at Will Pits included remains of the eggs and the female.
Pintail Anas acuta. A female was at the flooded workings on 17th September, followed on 7th November by separate male (Will Pits Scrape) and female (flooded workings).
Garganey Anas querquedula. A male was seen at flooded workings (south of Fisons’ Road and north of Melvyn’s Tram) on 26th May (MP).
Shoveler Anas clypeata. January-February totals did not exceed two, but the March maxima were eight on 26th and 16 on 28th. Counts in April exceeded 10 on 2nd (38) and 26th (58). Subsequent monthly totals reached c.20 in May (on 12th), but during June-October did not exceed 12 (on 6th July). In the final two months, the sole record was of two on 7th November.
Common Pochard Aythya ferina. A male was at flooded workings on 9th March.
Tufted Duck Aythya fuligula. The maximum in January-February was three, with up to 14 in March (including five pairs on 16th). April figures reached 18 on 17th and 24+ on 24th, the latter a record total. The May-June maximum was 10 on 5th May and 18th June. Apart from up to four in July to 12th, the only other records were odd singles on 2nd/6th September and 2nd October.
Goosander Mergus merganser. Totals – mostly from Will Pits Scrape – in the early months included two of 21, a record count. These were on 14th February (13 males) and 1st March (10 males). Other February figures included 10 on 9th, with March numbers otherwise reaching 10 on 9th and 11 on 26th. April counts began well, with 15 on 2nd and 18 on 4th, then seven on 8th, decreasing to four on 10th, then six on 11th and three on 15th. Five were present on 21st November.
Grey Partridge Perdix perdix. Encountered on 15 dates, although virtually unreported from midMarch to mid-October. In January, six were in Chadwick’s Field on 4th, with six again, roosting on the Thorne Colliery spoilheap, on 16th. Two were in a field near the Paraffin Works ruin on 16th March. In May, pairs were at the disused Swinefleet Peat Works on 5th and on the colliery spoilheap on 15th. In the latter area there were 10 on 17th October. In a field near the Paraffin Works ruin there were 18 on 1st/10th November, with a further November record of five in Chadwick’s Field on 26th. There were six December records, all from the colliery/Chadwick’s Field area. The number generally increased from five on 3rd/10th to 10 on 23rd.
Common Pheasant Phasianus colchicus. The maximum was 50+ on several November dates, the favoured location being Chadwick’s Field. There were also 43 in the field on 23rd December. Bred at Green Belt.
Great Cormorant Phalacrocorax carbo. One headed south on 2nd August. In September, two flew overhead on 6th/18th, plus one south on 23rd. One passed high to the north on 13th November.
Little Egret Egretta garzetta. Three records, from the flooded workings. On 5th July, four flew low to the south. In September, seen on 2nd/16th, when singles both came from the north and diverted to the west (all BPW). The fourth-sixth records for Thorne Moors.
Grey Heron Ardea cinerea. There were two on 18th June and three on 6th July, with other records of singles throughout the year.
Little Grebe Tachybaptus ruficollis. Records in March came from Bell’s Pond and Inkle Moor Pond, with the first being two at Bell’s Pond on 15th. There were singles at Bells’s Pond and Inkle Moor Pond on 16th/18th March, and at Inkle Moor Pond and Will Pits Scrape on both 23rd March and 8th April. Present at Will Pits Scrape and the flooded workings north of Fisons’ Road on 24th April (four+) and 26th May (two+), and on those floods alone on 5th/15th May and 10th July (all singles). At Will Pits Scrape, there was one on 26th April and three on 23rd June, with one at the flooded workings north of Fisons’ Road on 10th July. Named locations in August were Will Pits Scrape (one on 2nd) and the flooded workings north of Fisons’ Road (two on 17th and one on 23rd).
Great Crested Grebe Podiceps cristatus. An adult was present at Will Pits Scrape on 27th May, with two at ‘Green Belt floods’ on 11th June. An immature was at Will Pits Scrape on 12th July.
Black-necked Grebe Podiceps nigricollis. From this year, records at the flooded workings extended to both north and south of Fisons’ Road. These observations are, however, not differentiated here, but united as the flooded workings. Black-necked Grebes may have been present at Will Pits Scrape on 26th April. However, all certain records were from the flooded workings, where two were recorded 7th May-18th June. At a location to the south of Fisons’ Road, two “small” young were observed with their parents on 2nd June. They were seen subsequently, but on 18th there was only one “well grown” young bird with the adults, but with no further record of juveniles.
Of related interest, a juvenile Black-necked Grebe picked up in Moorends was released at Thorne Delves fishponds. Here it was present 5th-9th August.
Red Kite Milvus milvus. One flew south on 4th April (BSt), and one was seen north of Will Pits on 24th June (RB).
Marsh Harrier Circus aeruginosus. Recorded in all months, but with only one February record and two December records. Age/sex are given as reported. January records involved immature males on 1st/4th, a second-year male on 12th, and a male on 28th. There was also a male on 20th February. Records resumed in the second half of March, with a male and an immature male on 15th, an immature male on 18th, and a male on 26th-27th/29th. Females/‘creamcrowns’ were seen on 16th/23rd/26th.
On 2nd April there were four-six Marsh Harriers, then two on 4th. These were followed by a male on 9th and single females/‘creamcrowns’ on 10th-11th/13th. On 14th-15th, a pair displayed at Will Pits Scrape, mobbing a Common Buzzard on the first date. There were intermittent records of females/‘creamcrowns’ to the end of the month. There was also a male on 20th/26th-27th. Higher totals were four on 17th, three ‘creamcrowns’ on 24th, and three (including single male and female) on 26th. In May, there were records of one-two females/‘creamcrowns’ in the first half, plus an adult female and two ‘creamcrowns’ on 1st and three ‘creamcrowns’ on 5th. Also a male on 12th/15th. Later May sightings involved 17th (two ‘creamcrowns’) and 26th (an immature male and two females). In June, there were records of single females/‘creamcrowns’ on 2nd/15th/26th, two males on 23rd, and an immature male on 28th. Also four on 11th (including a ‘creamcrown’) and two on 20th.
July began with four on 3rd, including a female and juvenile. There were single male and ‘creamcrown’ on 5th, the former taking a young Black-headed Gull. Next day, the three recorded were an adult male, female and immature. There were further records on 9th (a male), 12th (two), 17th (a ‘creamcrown’ and juvenile), 24th (three, including a female), 30th (a male, three ‘creamcrowns’ and a juvenile) and 31st (two, including a ‘creamcrown’). During August, there were numerous records, beginning with a third-year male and an immature on 2nd. Next day there was a third-year male and juvenile. On 7th there were two adult males and three juveniles. The third-year male and a ‘creamcrown’ were logged on 10th, with up to two ‘creamcrowns’ during 11th-14th, with two juveniles also on 14th. The total on 15th was an immature male, an adult female and two ‘creamcrowns’. There was a male on 16th, a third-year male on 19th, and a male on 27th. In this period there were up to three ‘creamcrowns’. The count on 28th was four (single adult male, adult female, ‘creamcrown’ and juvenile), with the same number on 30th (single adult male, female and two juveniles).
There were at least six on 2nd September: an adult male, two third-year males and three ‘creamcrowns’ together. One ‘creamcrown’ seen separately was mobbed by Carrion Crows over Will Pits. On 3rd, eight flew to roost at ‘Green Belt floods’, a Thorne Moors record count. Until 16th there were up to three ‘creamcrowns’ recorded, with two males on 5th and an adult male on 11th, on which latter date there was also a juvenile. On 18th, there was a third-year male, two ‘creamcrowns’ and a juvenile. The third-year male was seen again on 20th, with a male next day as well. Other records of females/‘creamcrowns’ included two ‘creamcrowns’ on 21st-22nd, on which latter date three soaring Marsh Harriers brought the day count to five. There were single females/‘creamcrowns’ to the end of the month. On 1st October a male and female were logged, with a male, adult female and juvenile next day. A juvenile was also seen on 7th. Subsequent totals of one-three included a male on 8th and an immature male on 27th, plus occasional females and up to two ‘creamcrowns’. However, on 22nd there were single adult male, juvenile male, female and one other.
Records diminished through November. On 2nd, there was a male, two ‘creamcrowns’ and one other. Next day, a male and two ‘creamcrowns’ roosted at flooded workings north of Fisons’ Road. On 5th, an immature male, three ‘creamcrowns’ and a juvenile were reported. The highest count of the month was on 7th, with an adult male, three ‘creamcrowns’ and two juveniles. There were seven subsequent November dates: 8th/11th (single immature males), 12th/19th/26th (single ‘creamcrowns’), 15th (two ‘creamcrowns’) and 20th (an adult male). In December, there was a male and two ‘creamcrowns’ on 6th and a ‘creamcrown’ on 31st.
Hen Harrier Circus cyaneus. Age/sex are given as reported. The first of nine January reports was of two females on 2nd, followed by an adult male on 7th. On 12th, two adult males and a juvenile were pursuing Linnets at Chadwick’s Field, with the juvenile also there during 13th-20th. Males were logged on 28th January and 13th/20th February, with a ‘ringtail’ on 1st/13th March.
An unseasonal male was present on 1st May, with a lone ‘ringtail’ on 30th August. Males were reported on 7th/18th October and 7th November, with ‘ringtail’ records on three November dates (to 14th) and 8th December.
Eurasian Sparrowhawk Accipiter nisus. Daily maxima never exceeded two, with reports in most months. However, between 28th April-10th August, there were only records (of singles) on 26th May, 24th June and 6th July. On 19th August a male chased Greenshanks, and on 19th November a female killed a Wood Pigeon.
Common Buzzard Buteo buteo. The sole moors record in January was one on 31st. However, one wintered in the Goole Fields – Swinefleet Common – Moors Farm area, and the same bird may still have been present on 11th April. Singles in March and early April may have been the resident bird, as the records mostly emanated from Goole Moor. In the second half of April, records of singles were eclipsed by two on occasion (mobbed by displaying Marsh Harriers at Will Pits Scrape on 14th), four on 17th and three on 27th. During May-August, one-two observed at intervals (but only on one June date), plus three on 12th July. These included one mobbed by two Carrion Crows on 14th May and another heading south-east on 24th July. Singles were logged in September, except four on 5th (“left singly from Long Meadow hedge”, presumably a post-roost dispersal) and two on 9th. There were two October records, on 11th (one) and 17th (two). The only record in November concerned four high over Will Pits on 7th, and lastly there was one on 23rd December.
Golden Eagle Aquila chrysaetos. A falconer’s bird was over the Goole Fields-Thorne Moors area during 11th-17th October (JJ, CH). On 11th, it landed on Goole Fields.
Osprey Pandion haliaetus. On 8th April, one perched in a prominent birch Betula on Crowle Moor, being first seen at 10.30hrs, and still there at 13.30hrs (RB).
Common Kestrel Falco tinnunculus. Daily maxima occasionally reached four+, exceeded by six+ on 17th April and six on 9th September.
Red-footed Falcon Falco vespertinus. An adult male flew over Shoulder o’ Mutton Tram, heading north-west, on 5th May (PH, PA).
Merlin Falco columbarius. On 12th January, a female/immature was at Chadwick’s Field (attracted to Linnets) and a male was over ‘Middle Moor’. The Chadwick’s Field Linnets drew
Merlins again in January, on 13th (one), 15th (one male) and 20th (one female). A juvenile was on Goole Moor on 30th July, with a male reported on 1st August. In October, single female/immatures were over the flooded workings on 14th/19th. Finally, on 23rd December, reported from Moorends recreation ground and the flooded workings, the latter involving a male.
Hobby Falco subbuteo. There were two from 23rd April, three on 1st May, and other May reports of one-two+, but six on 7th. June began with four on 2nd, then one-two, including two on 18th, followed by 20+ north of Will Pits on 20th (LJD, RJS). Up to two subsequently were succeeded by 20, again north of Will Pits, on 3rd July, “after emerging dragonfly swarm” (SR). These are the highest ever Yorkshire counts. Later July counts included four on 5th-6th/9th, 13 on 6th (BSt) and six on 13th. There were 18+ on 17th, once again north of Will Pits (WHP), nine+ on 24th and eight on 31st. Two on 30th July were described as an adult and juvenile. The numerous August counts never exceeded three+. There were two in early September (to 5th), six on 9th and three+ on 11th. There was then a laggard on 22nd September (RW), concluding an eventful year for this species. There was interaction between Hobbies and Peregrine Falcons on 28th June and 17th July.
Peregrine Falcon Falco peregrinus. Age/sex are given as reported. Rare before April, with single male and female on 12th January, and then a female on 16th March. Single Peregrines (no details) appeared in April on 4th/10th/23rd, followed by a “small male” with Hobbies on 28th June.
More regular from mid-July to the end of October. On 17th July a female and a juvenile were watched, with the juvenile obtaining a kill on 24th and recorded again on 7th August, on which latter date a male was also present. A female was seen 10th-16th August, and later in the month two were recorded on 19th (two juvenile females) and 28th (a male and juvenile female). In September, there was a male and an immature on 5th, two together (one carrying prey) on 9th, and one on 22nd-23rd. October began with an adult male and female on 2nd, one heading south on 14th, and singles on 17th/27th. There were records on only three remaining dates: 22nd-23rd November (two) and 23rd December (a female).
Water Rail Rallus aquaticus. After one on 1st January, there were singles on three dates in April, two+ on 15th May, one was reported between 14th June-2nd July (Middleton Eco Consultancy), one on 3rd July, and singles on four dates in August-September. The locations were flooded workings/Shoulder o’ Mutton, the Southern Canals/Viewing Platform/’Middle Moor’ area, and (on 17th August) Goole Moor. Finally, one was calling on 2nd November along Western Boundary Drain.
Spotted Crake Porzana porzana. During the annual European Nightjar survey, one was heard on 18th-19th June (Middleton Eco Consultancy). The second Thorne Moors record.
Moorhen Gallinula chloropus. Unrecorded November-December. Maxima from the remaining months reached four, plus four adults and additional young birds on 18th June.
Common Coot Fulica atra. Only recorded in April. One was at Inkle Moor Pond on 4th, one at Will Pits Scrape on 10th, and one (unrecorded location) on 27th.
Common Crane Grus grus. Two were seen regularly from 2nd April-30th August. There were three on 2nd August, one of them heading west. During the year, many of the reports were from the flooded parts of Goole Moor and adjacent Thorne Waste, the latter centred on the Shoulder o’ Mutton area.
Oystercatcher Haematopus ostralegus. One was at flooded workings on 2nd April.
Little Ringed Plover Charadrius dubius. In April, the first was one on 17th, followed by one+ on 26th. The next, three juveniles, were not reported until 15th August, then two juveniles on 17th, with other August records including the year’s maximum (six on 19th) and last (two on 23rd). All records were from the flooded workings.
Ringed Plover Charadrius hiaticula. None appeared until a single on 7th August, with seven on 10th-11th August. This record was followed by many others to the end of September, with counts in excess of 10 on 14th August (14+), 15th August (13), 23rd August (12), 28th August (16), 2nd September (17), 5th September (15) and 6th September (18). There were then one-four to the last (single) on 28th September.
European Golden Plover Pluvialis apricaria. Until mid-August, the only record was of six north on 17th January. In August, there were birds overhead on 17th (three) and 18th (c.30), plus four transient birds on 8th October. November records commenced with 35 and 20+ over on 20th, followed by 121 in a field near Thorne Colliery on 26th.
Grey Plover Pluvialis squatarola. One flew north on 28th September, and one was at the flooded workings along Fisons’ Road on 2nd October.
Northern Lapwing Vanellus vanellus. Reported in all months except January, with FebruaryMay counts only exceeding 32 (26th April) when c.70 were present on 1st March. During Junelate July, the maximum was c.150 on 23rd June. From late July-mid-August the overall counts were higher. There were c.500 on flooded workings on 26th July and 326 on 30th July. In August to 19th, there were several totals of up to c.200, plus 897 on 1st and c.300 on 7th. The September numbers commenced with 95 on 2nd, but then no more than 15 until c.200 on 30th. This was a shortlived peak, with only 20 on 2nd October. On 20th November there were 100+, and 38 on 26th November, but with no December figures over 11.
West of Will Pits a pair was displaying on 8th March and 11th April. Five pairs were on Rawcliffe Moor-Goole Moor on 23rd March. More specifically near Creyke’s, three pairs were territorial (mobbing a Marsh Harrier on 13th April) until at least 13th May. There was no evidence of breeding success.
Dunlin Calidris alpina. There were only two records in the first half of the year: two on 26th April and one on 12th May. Returning birds appeared in July, with 13 on 12th and eight on 30th, all on Goole Moor. Frequently recorded throughout August-September, usually one-seven, but late August-early September counts reached 20 on 28th August, 15+ on 30th August, 31 on 5th September and 11 next day.
