Thorne Moors Bird Report 2001

Compiled by Bryan P. Wainwright
English and scientific names, and sequence of birds, follow the List of Birds of the Western Palearctic (British Birds Ltd, 1997).

Birds of conservation concern are marked according to the British Trust for Ornithology, Royal Society for the Protection of Birds and English Nature grading system. This system uses a Red or an Amber status for those bird species that are known to be declining. Red signifies high concern and Amber signifies medium concern. For this list, species that are non-breeding, or have not recently bred, on Thorne Moors, but are on the Red and Amber lists for elsewhere, are noted in brackets.

During the year, 149 species were recorded. A few species have been included in this report that were just outside the recording area. This is partly because these species are of particular conservation concern and the records would not otherwise appear in any report. These species may also rely on some of the resources available to them on the moors, and may otherwise not be present in those areas. Such a resource may be an increase of invertebrates towards the moorland edge, vital for breeding success in the otherwise relatively sterile arable fields. Where these records are mentioned in this report, it is always made clear whether the record was from the peat moor or not, as this may be relevant in future research. 

Daily counts of common widespread resident species (and a few migrants) cannot be regarded as full counts, as no one person can cover every area of the 1918 ha of Thorne Moors in a day. Counts for numbers of breeding males of species such as warblers can only be taken as maximum possible numbers. The counts are possibly an over-estimate of the true numbers of territorial males and the figures should not be used as hard and fast figures in the same manner that true census figures can be. The area covered by counts cannot be considered complete, as for instance there are frequently no counts at all for some areas such as Crowle Moors. In a similar manner the following monthly figures can only be taken as sample counts. For months when there were no counts or the species was just recorded as ‘present’ the notation ‘nc’ is used. Records (of wetland species mainly) that do not have the area name given are records from the flooded workings. Birds are adults unless otherwise stated.

 

Little Grebe Tachybaptus ruficollis
The maximum day count was of six, on 6th May with one at the flooded workings north of Fisons’ Road, two at the Paraffin Cuttings, two at Inkle Moor Pond and one at Casson’s Marsh. Will Pits Scrape regularly had Little Grebes present also. No more than two birds were seen at any one area at a time.

Birds of prey
Sites given for raptors are general. Usually only the first area of observation is stated, except where sites were very far apart. A comma between records of the same date means separate records. Depending on views the same bird of prey may be recorded differently by different observers. For example with Marsh Harrier; recorded as a female by one observer or a cream-crown by another, therefore with the following records this is taken into account and only the minimum number of birds per day is taken. Totals are the minimum possible numbers, calculated for all areas, plumages and observers for that day. All are adult birds, unless otherwise stated. Some birds are not aged and sexed due to distance or poor views.

On 7th August seven birds were present, the three smaller birds with shorter bills were in full summer plumage and were considered to be the nominate C.a. schinzii, the four larger juvenile birds with longer bills were considered to be C.a. alpina (BPW). A similar observation was made on 10th August, when 12 smaller adults and juveniles were considered to be C.a. schinzii and the remaining two summer plumaged birds were considered to be C.a. alpina because of their structure and larger size (more like Curlew Sandpiper) (BPW). Observations in the field are complicated however by the range of overlap in the various races of Dunlin, therefore identification is unproven.
Monthly maxima were: January 1, February nc, March nc, April 4, May 8, June 6, July 2, August 26, September 30, October 5, November 9, December 5.

 

Ruff Philomachus pugnax (Amber List)
The first record was not until 26th June, when five were present; four males and one female. All records were from the flooded workings. These five were observed again on 28th and 30th June. This number was not exceeded until 24th August when six were present. On 20th September 13 were present (one male and 12 females), on 4th October 11 came in to the flooded workings and then flew E. On 18th November 12 flew S over Green Belt and this was the last record. All other records were in single figures.


Jack Snipe Lymnocryptes minimus (Amber List) 
One was flushed from the edge of Fisons’ Road near Green Belt on 7th October, and two were present at the flooded workings on 10th October. A single was flushed from the SW edge of the moors on 27th November, and another was at the flooded workings on 16th December.


Common Snipe Gallinago gallinago Amber List
Passage during September provided the highest counts from the flooded workings. After 14 on 2nd and 19 on 12th, the year’s maximum of 40 were seen in small groups flying over this area on 20th, and there were 28 at the flooded workings on 29th. The only other double figure counts were in November, with 20+ on 2nd and 23 on 4th. Drumming was observed on 30th April at Crowle Moor near Swinefleet Warping Drain. A single bird was drumming over the Southern Canals on 1st May. Again a single bird was drumming over the E end of Southern Canals and another at the Northern Canals on 27th May. The last drumming record was of a single at the Rhododendron Path and another at E end of the Canal towpath on 14th July. 
Monthly maxima were: January 9, February nc, March nc, April 1, May 1, June 3, July 2, August 14, September 40, October 8, November 23, December 3.


Woodcock Scolopax rusticola Amber List
There were 28 records in all, virtually all of one or two birds from a wide variety of areas, with most records from Will Pits usually at night or at dusk and dawn. Four were recorded in Will Pits on 12th December. Other records came from Goole Moor, ‘Middle Moor’, colliery area, Canal towpath, Angle Drain, Green Belt, and Pony Bridge Marsh. Up to two were observed roding on seven dates in Will Pits from 30th April to 24th June. Apart from this one was ‘chipping’ at Angle Drain on 30th June. 


Black-tailed Godwit Limosa limosa (Red List)
In April, one flew over W on 21st and one flew E over Will Pits Scrape on 29th. At the flooded workings two were present on 28th June, before one left NE. In July, two arrived on 4th, ten were observed on 10th and on 16th one was present. 
On 22nd July three males in full summer plumage came in to the flooded workings. These were considered to be of the race L.l. islandica (RJS).


Whimbrel Numenius phaeopus (Amber List)
One was observed from 28th-30th April. In May there were singles on 1st and 9th, and the final record was of three flying S on 24th August.

 

Eurasian Curlew N. arquata Amber List
Passage was light through April and May, with no more than two birds per day. First record was of two heading NW on 8th April. There were only two dates when there were more than two birds, on 26th June and 14th September, which both had four recorded. 


Spotted Redshank Tringa erythropus
A summer plumaged bird was present on 26th June, and single winter plumaged birds were seen on 23rd August and 28th September.


Common Redshank T. totanus Amber List
Apart from a couple of January records of singles non were seen until May. Nearly all records were of one or two birds, the exceptions being three on 26th June, 4th July and 10th September and four on 28th June. 


Common Greenshank T. nebularia (Amber List)
Spring records were very few with the first being of three on 9th May. Most records involved between one and three birds, the exceptions being seven on 18th July and four on 31st August at Green Belt. Apart from these areas there was a single at Will Pits Scrape on 21st August and a single was flushed from Thorne Waste Drain on 2nd September.


Green Sandpiper T. ochropus
There was a single winter record in the first half of the year, of two at Jones Cable on 28th January. Maximum year count was at least nine on 10th August, with six at Green Belt and five at the flooded workings. The second highest count was of seven in a drain near Jones Cable on 2nd September. Besides these areas, a single was seen to fly over Elmhirst Tram (presumably) to Casson’s Marsh where a bird was observed, on 26th July; two others were seen on the same date, one each at the flooded workings and at Green Belt Scrape. Records from the latter months were of one flushed from Thorne Waste Drain on 18th November, and one over Jones Cable on 16th December.

 

Wood Sandpiper T. glareola (Amber List)
All six records were in August; one juvenile was seen on 21st, two on 23rd (one at Green Belt), two on 24th, one on 26th and one on 28th and one on 31st. 


Common Sandpiper Actitis hypoleucos
In total, 14 records were received, so not quite as frequently encountered as Green Sandpiper. All records came from the flooded workings, and on no date were more than three present. Records were received from May (12th) to September (2nd).


Turnstone Arenaria interpres (Amber List)
The only record was of one flying E over the flooded workings on 23rd August. 


Gulls
Except for Black-headed Gulls, landed gulls were only ever found at the flooded workings north of Fisons’ Road, unless otherwise stated. This is also the area where gulls roosted, though many gulls would land, bathe, preen and drink before continuing to a different roost site, which was often NE towards the River Humber. Other gulls did not stop at all and just over-flew to/from other roost sites. This was more often the case in mornings when gulls had departed their roosts. Counts of gulls were not made systematically. 


Black-headed Gull L. ridibundus
Again there were three main colonies this year, and conservative counts of sitting birds were taken in May. This put breeding numbers at 150 pairs at Will Pits Scrape, 170 pairs at the flooded workings N of Shearburn & Pitts Drain, and 200 pairs at the main colony at the flooded workings N of Fisons’ Road. This gives a total of 520 pairs, which was marginally fewer than last year. The first chicks were noted on 9th May, when about 50 were present at the flooded workings, and unfledged chicks were still about on 12th July. Numbers of young hatched were 235 young counted (and 271 adults) at Will Pits Scrape on 17th June. At least 224 young from all of the flooded workings were counted on 14th and 17th June.
Roost counts outside the breeding season were few. The best counts were 137 on 28th October to roost, but most over-flew the moors and carried on NE, as on 28th October and the following evening when 104 did the same. On 29th December, 555 flew over the W end of the flooded, a few stopping but most eventually departing NE. 
Monthly maxima were: January 30, February nc, March nc, April 1600, May 700, June 1000, July 100, August 977, September 295, October 214, November 34, December 555.
There were three ringing recoveries on Thorne Moors in 2001, of birds ringed as nestlings and recovered as adults. Two were obtained on 2nd June and the other on 17th June at the flooded workings. One bird had been ringed at Wheldrake Ings, North Yorkshire on 22nd June 1997, the second on Hatfield Moors, on 14th June 1997, and the last bird had been ringed at Lound near Retford, Nottinghamshire on 9th July 1995 (PBo).
Two birds ringed as nestlings on Thorne Moors were recovered at the following sites. The first ringed on 2nd June 2001 was recovered on 27th June at Goole. The second ringed on 17th June 2001 was recovered on 2nd July at Stourton, near Leeds, West Yorkshire (PBo). 


Common Gull L. canus (Amber List)
Observed over-flying the moors, or on marginal fields, with the highest count of 11 from the field between Whaley Balk and Inkle Moor on 22nd December. Records of landed birds from the peat moors are infrequent and only single-figure day counts were obtained. Two left the moor’s roost at the W end of the flooded workings on the morning of 3rd January, and five returned there the same evening. Apart from the flooded workings, there was one record of two immature landed birds at Will Pits Scrape on 3rd June, where they met some hostility from the breeding Black-headed Gulls. 
Monthly maxima were: January 6, February nc, March nc, April 1, May nc, June 2, July 1, August 1, September 6, October 3, November 4, December 11.


Lesser Black-backed Gull L. fuscus (Amber List)
The commonest species of gull in summer (May-September) and regularly roosts on the moors.Observed roosting on the moors from late June onwards, with 30+ present on 24th building to the year’s maximum on 28th. These roosts as usual contained mainly immature birds.
Monthly maxima were: January 2, February nc, March nc, April 16, May 170, June 478, July 156, August 300+, September c.30, October 21, November 2+, December 1.

Herring Gull L. argentatus (Amber List)
Generally the commonest non-breeding species and regularly roosts on the moors. The year’s highest counts were associated with roosts. For instance 81 were leaving W on the morning of 1st January and 207 returned that evening. On 3rd January 754 left the moors roost at the W end of the flooded workings and headed W and 392 return there that evening. An all time maximum count of 1650 was set on the evening of 28th October, as birds headed over the moors NE to roost (BPW). 
Monthly maxima were: January 754, February nc, March nc, April 13, May 4, June 1, July nc, August 300, September 40, October 1650, November 600+, December 195.

 

Great Black-backed Gull L. marinus
A count of 30 leaving W in the morning and 41 returning in the evening was obtained on 1st January. On 3rd January 165 left the moors roost at the W end of the flooded workings and headed W, while many others remained, 165 returned there that evening. The total for the latter date was the year’s maximum. 
Monthly maxima were: January 231, February nc, March nc, April 95, May 57, June 7, July 10, August 1, September 23, October 200, November 7, December 90.

Arctic Tern S. paradisaea
Two passed low N calling over the W end of the flooded workings on 6th May (BPW). 

 

Rock Dove Columba livia
Feral birds are present year round in small numbers. At the colliery there were nine on 17th December.


Stock Dove C. oenas Amber List
Commonest on the W side of the moors, where there were 60 at Inkle Moor/Paraffin Cuttings fields on 5th January and 10 at Inkle Moor on 26th July. Not recorded in February, March or May.


Wood Pigeon C. palumbus 
Highest count was from fields at Woodpecker Corner on 3rd March.
Monthly maxima were: January 132, February nc, March 500+, April 1, May 30, June 10, July 7, August 57, September 16, October 16, November 120, December 200.


Collared Dove Streptopelia decaocto
Small numbers are sometimes seen at some areas around the moors. These places include Top Moor Farm, the colliery road-bridge and Jones Cable. Jones Cable had the only double figure counts of 14 on 21st August and 24 on 29th September. Records from over the peat moors were few. On 10th April two flew from the Paraffin Cuttings N to Rawcliffe Moor, and on 17th June one was seen at Green Belt. 


Turtle Dove S. turtur Red List
Maximum count was six on 27th May (ML), 27th June and 25th July (BPW) and these equal recent years’ maximum day counts on 10th and l4th July 1996 and on 1st June 1998. First date was the earliest ever, of a single purring in the colliery area (BPW). A maximum of 13 pairs bred (estimate), from records received for purring males in the following areas. Three colliery area (including one on SW edge), and single males at Will Pits, Elmhirst Wood, Rawcliffe Moor, Green Belt, Goole Moor, Casson’s, W of Pony Bridge Wood (comp. 66), Alder Thicket, Canal towpath and (E end) Jones Cable. First and last dates were 1st May and 14th October, the latest ever, at Northern Goole Moor (PB).

 

Common Cuckoo Cuculus canorus
Maximum was eight on 7th May and 3rd June, and seven were recorded on several dates. First and last dates were 29th April and 27th June. 


Barn Owl Tyto alba (Amber List)
A bird was flushed from a Magpie’s nest in the colliery area on 18th April (JGH). 


Little Owl Athene noctua
Two were heard along the colliery road on 9th May (BPW) and one flew from the moors to Jones Cable on 25th November (RJS). 


Tawny Owl Strix aluco
Adults were heard from the colliery area, Will Pits, Elmhirst Wood, Rawcliffe Moor, Green Belt, Goole Moor, Paraffin area and Yorkshire Triangle. Maximum adult count was three on several dates. Breeding took place in Will Pits where two young were frequently heard from 3rd June. An adult and young were heard at Yorkshire Triangle, on 14th June. At least seven young were counted in the colliery area to Woodpecker Corner on 11th July. 


Long-eared Owl Asio otus
Records were received from a wide variety of areas, and the recorded has attempted to assign records to family territories as follows. A family in the N end of Will Pits was also seen along Bank Top (Swinefleet Warping Drain). Records from the Paraffin area and the southern end of Snaith & Cowick Moor (around the ‘S’ bend of Fisons’ Road) are thought to be one family. Records from the Southern Canals and Mill Drain Marsh are assumed to be of another family; and records from Limberlost Tram, Pony Bridge Wood and Pony Bridge Marsh of another. A family was present at Angle Drain and was also recorded at Collis’s and Elmhirst Trams, and another family was present at Green Belt and in the colliery area. This gives six areas in which young were heard, however this is conservative with the total possibly nearer eight, since the Limberlost young were a long distance from the Pony Bridge young, and there may have been a family towards the Alder Thicket grouped in with the others. There were sightings of hunting birds along the edge of Will Pits on 16th and 22nd May, and at Pony Bridge Wood on 1st September. Excellent views of dispersed young could be gained along Fisons’ Road at night, occasionally adult birds were also seen in the open presumably looking to feed their wandering offspring, as on 19th, 26th and 29th June. Good views were also had of quartering adults from the observation platform on the Canal towpath the evenings of 29th, 30th June and 6th July.


Short-eared Owl A. flammeus (Amber List)
One flew E from Crowle Moor on 10th October (SH). On the evening of 16th December one was over Southern Canals with three Hen Harriers (RJS).


European Nightjar Caprimulgus europaeus Red List
Surveys were conducted on nights between 31st May to 8th June and from 9th July to 14th July. The whole of the moors was covered in a single night on 8th June and 14th July. This revealed a total of 24 males, which is a further reduction in numbers (SH et al.). First and last dates were 21st May and 24th July.


Common Swift Apus apus
Maximum was of 2000 on 18th May, an all time record (RA). On 30th June (WHP) and 11th July 1000+ (BPW) were counted (going W on the latter date), which equal the previous all time record count for Thorne Moors (on 23rd July 2000). The high count in August was due to a movement S. First and last dates were 29th April and 10th September. 
Monthly maxima were: April 60, May 2000, June 1000+, July 1000, August 526, September 3.

 

Common Kingfisher Alcedo atthis (Amber List)
A single was seen along the W edge of the moors on 28th August. Five records of singles were from Bell’s Pond or adjoining drains from 4th October onwards


Green Woodpecker Picus viridis Amber List
The maximum count was four on several dates: 3rd January, 24th August and 4th November. The colliery area and Will Pits were the most regular areas, though the birds could be seen in any wooded area. An adult was prospecting a hole at Northern Goole Moor on 10th May, however no subsequent breeding took place here. Breeding was noted in Will Pits on 5th June, when an adult was seen at a nest hole in a Basford Willow Salix x rubens. One juvenile was seen at the Southern Canals, on 29th August.


Great Spotted Woodpecker Dendrocopos major
Maximum number of adults was five on 4th May (RA), and this equals the all time record on 2lst April 1996. Breeding took place at Will Pits Scrape in a willow, with alarm calling and drumming there, and calling young were being fed by both parents on 5th June. The young had flown by 14th June. 

 
Lesser Spotted Woodpecker D. minor
One was along Elmhirst Tram on 26th July, and what was presumed to be a second was noted flying over Will Pits from Crowle Moor on the same date (ML). A female flew over Fisons’ Road from SE side of Will Pits on 17th December (BPW). 


Sky Lark Alauda arvensis Red List
Cold weather movement on 1st January produced the high count with most birds moving NW in the morning. The October peak was of birds moving S on 4th. The highest count of the year, on 24th December, involved c.80 NNE and 50 others present in a field E of Pony Bridge Marsh. The previous day, 111 were noted heading S. On 29th December, 16 were present at English Nature’s field near Green Belt, with a further 13 moving N low over the moors.
Monthly maxima were: January 33, February nc, March nc, April 3, May 6, June 4, July 2, August 1, September nc, October 60+, November 19, December 130+.


Sand Martin Riparia riparia (Amber List)
The year’s maximum count was on 11th August when at least 3000 were counted and this is an all time maximum (RJS). Passage lasted from 9 a.m. when rain forced the main stream E over the moors (they were probably following the River Don S at first), and passage slowed abruptly by 11 a.m. due to heavy rain. First and last dates were, 5th April and 14th September.
Monthly maxima were: April 11, May 2, June 1, July 45, August 3000, September 134.

 

Barn Swallow Hirundo rustica (Amber List)
Generally very low numbers, the year’s maximum was due to a roost at Mill Drain Marsh on the morning of 29th April. On 19th September during strong winds and rain, 45 birds were present at the Shoulder o’ Mutton Tram, with c.26 resting on the bare peat there whilst others tried to feed up despite the weather. Six juveniles with two adults were again seen in the vicinity of the colliery buildings, where they probably bred, on 25th July. First and last dates were 1st April and 10th October.
Monthly maxima were: April 50, May 21, June 2, July 8, August 33, September 45, October 6.

 

House Martin Delichon urbica
There were two exceptions to the low numbers, namely 60+ on 29th April and 62 on 10th September. Four other double figure counts were all below 40. First and last dates were 28th April and 24th September.

Yellow Wagtail Motacilla flava
Records came from the flooded workings or other bare areas. The first date is the earliest ever for Thorne Moors (BPW). The first double-figure count was of 20+ on 27th July and this was the year’s maximum, with the same figure attained on 11th and 24th August. Bred at the flooded workings where one was observed carrying food on 11th and 26th June and five were seen including young on 10th August. First and last dates were 21st April and 24th September.

A nest found on 5th May had three eggs and by 8th May contained five, unfortunately the nest was found to have been destroyed on 5th June, though one juvenile was seen in the vicinity. Four fledged young from two nests were seen in Will Pits, with more fledged young at Shearburn & Pitts Drain at the flooded workings, on 23rd July. One recently fledged young was seen along the Canal Tow Path on 7th August.

Rufous Nightingale Luscinia megarhynchos Amber List
This species was the subject of a dissertation study by BPW, with grant aid from English Nature. Fourteen singing males held territories, with seven at Will Pits (one just over Swinefleet Warping Drain, at the Yorkshire Triangle). Other areas were the colliery area (one), Green Belt (one), Limberlost Tram (two), Goole Moor (two) and western edge between the Alder Thicket and the Paraffin area (one). A possible roving 15th unpaired male may have been present at Will Pits, as there were several one off observations of a bird additional to the ones known to be present along the road. One or more young were seen in Will Pits on 30th June and 2nd July. Last singing date was 2nd July. On the last date at Will Pits only ‘croaking’ and ‘wheeting’ notes were heard from what were probably young birds. First and last dates were 28th April and 6th July.


Black Redstart Phoenicurus ochruros
An adult male was observed feeding on insects at the colliery buildings on 5th April (WHP). The fifth record for Thorne Moors.

 

Common Redstart P. phoenicurus
A male was at Collis’s Tram on 12th April, the earliest ever (JGH). A flighty and elusive bird was seen briefly at Middle Moor Tram on 21st and 28th August (RJS).
 
Whinchat Saxicola rubetra
At least two pairs bred along S side of Fisons’ Road, with up to four males and one female seen here on 12th May. One pair bred at Pony Bridge Marsh and one pair bred near the Observation Platform. One nest along Fisons’ Road contained six eggs on 27th June, five of these hatched and the young were being fed on 10th July. A single young was also seen away from the nesting areas, at the flooded workings, on 28th August and on the last date. Nocturnal singing was noted from the westernmost male along Fisons’ Road on 24th June (at 3.00 a.m.), 26th June (at 3.30 a.m.) and 28th June (at 3.30 a.m.) (BPW). First and last dates were 29th April and 2nd September.


Common Stonechat S. torquata (Amber list)
Seen mostly in more open areas such as the flooded workings, ‘Middle Moor’, and the Canals area. Remarkably a pair bred for the first time since 1947, a written account by PCR will be published in Thorne and Hatfield Moors Papers Vol. 6. The pair was first noted on 12th May, when the male was singing. The male was again observed singing on 17th and 26th May and 11th June, with the female was being seen on 17th and 26th June. The resemblance of fledged young to females makes them difficult to separate, and the number of young raised is unknown. Maximum count was nine on 9th October, with three at the W end of the flooded workings near Fisons’ Road and six at the E end of Fisons’ Road on the S side; at least two were males. Seen all months except February, March and April. 


Northern Wheatear Oenanthe oenanthe
Of the few records this year most were from the flooded workings, except on the first date when a male was at Rawcliffe Moor, as was one, on 14th June. All records were of singles except three on 24th August. First and last dates were 10th April and 15th October.

Monthly maxima were: January 158, February nc, March 1, October 70+, November 135, December 36.

 

Song Thrush T. philomelos Red list
No double-figure day counts, however the highest count of the year found at least eight males present in Will Pits alone, on 24th June. Seven were in the same bush in the colliery area on 20th October.

Warblers

The following counts are not census counts and should not be treated as such, they are not all from the same date they are instead estimates by area from throughout the breeding season. Some counts represent the highest counts of breeding males ever recorded, but they have not been counted using proper census techniques and should be used with caution elsewhere. However even if some species have been inadvertently over-counted in some areas, for most species some areas of the moors have not been covered at all, so perhaps the estimates are not too far out.
