Thorne Moors Bird Report 2000
Compiled by Bryan P. Wainwright
English and scientific names, and sequence of birds, follow the List of Birds of the WesternPalearctic (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, 156 species were recorded, excluding an unidentified crake. A few species have been included in this report that were just outside the recording area; they appear in square brackets, 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 moor edge, vital for breeding success in the otherwise virtually 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 some future research.
Daily counts of common widespread resident (and a few migrants) species cannot be regarded as full counts, as no one person can cover every area of the 1918 hectares of Thorne Moors in a day. The following monthly figures can only be taken as sample counts. Records (of wetland species mainly) that do not have the area name given are records from the flooded workings.
Little Grebe Tachybaptus ruficollis
A maximum day count of six, were seen on 25th March, with two at the flooded workings north of Fisons' Road and four at Will Pits Scrape (maximum for latter area). Other area counts were one at Casson’s Marsh on several dates with 16th April being the first. At the Paraffin Cuttings two was the maximum on 5th March. One was at Pony Bridge Marsh on 26th March, two were at Bell’s Pond on 31st August, and one was at Goole Fields Reservoir on 7th May, and these were the only records for those areas, the latter also being the first ever there. Three young were seen at Will Pits Scrape on 23rd July. Two young were seen at the flooded workings on 29th July, but only one young was present by 8th and 15th August. First date was 12th February (one at Paraffin Cuttings), last date was 29th September (five were present at the Shoulder o’ Mutton and this was also the maximum count for all the flooded workings).
Black-necked Grebe Podiceps nigricollis (Amber List and listed by the Rare Breeding Birds Panel).

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. Totals are the minimum possible numbers, calculated for all areas, plumages and observers for that day. Adult birds, unless otherwise stated. Some birds are not aged and sexed due to distance or poor views.
European Honey-buzzard Pernis apivorus (Amber List)
On 20th September a single dark, probably immature, bird was observed at a distance flying low over the flooded workings to Will Pits Scrape. It was briefly accompanied by a slightly larger female Marsh Harrier giving good comparisons of flight etc. After being lost from view towards Will Pits Scrape for a short while, it returned over Mill Drain Marsh before heading low N over the flooded workings (BPW) this was rejected by the YNU. Following this sighting, a paler, normally coloured adult male bird was seen by two sets of observers on 24th September. RJS noted the bird at 9.40 hrs NE of the Shoulder o’ Mutton being mobbed by Carrion Crows as it passed over Will Pits Wood. JJ and PB saw it at 10.00 hrs being mobbed by corvids on the northern edge of the moors. It flew low over the observers showing its pale grey head and under-wing barring before continuing low towards Blackwater Dyke. RJS saw it again briefly over Will Pits Wood at 11.00 hrs.
Red Kite Milvus milvus (Red List)
At 14.20 hrs on 22nd March one was sighted coming from NW over the flooded workings, here it circled a couple of times before heading E at about 20 m height over the observer at Shoulder o’ Mutton, before eventually drifting off high to the S (RJS).

The only record was of two birds flying W over the flooded workings on 11th April.
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. Gulls counts were casually made except for Black-headed Gull, which were surveyed for the Seabird 2000 census.

There would be additional non-breeding immature birds loafing around each colony, as most Black-headed Gulls do not bred until their second summer. Roost counts outside the breeding season are few, however six flew over flooded workings N of Green Belt, some stopping briefly before all departed NE, on the evening of 21st December. Young were seen from 20th May on and some were fledged by 4th June. A count of 100 young from the colony N of Shearburn and Pitts Drain and 200 from the colony N of Fisons’ Road was obtained on 10th June (WHP). 105+ fledged young were counted on 25th June (RJS).
Monthly maxima were: January 5, February 193, March 1300+, April c.2000, May 1130+, June 2000+, July 300, August 400+, September 6, October 94, November 7, December 240.

One was found moribund at Green Belt Scrape on 25th August, later in the day it had gone, possibly predated. Two juvenile Marsh Harriers scavenged a dead immature bird (probably first-winter) at the flooded workings on 28th September. The year’s maximum (300+) was on 23rd July.
Monthly maxima were: January 1, February 0, March 8, April 140+, May 80+, June 48, July 300+, August 150, September c.150, October 20, November 0, December 1.
Herring Gull L. argentatus (Amber List)
Generally the commonest non-breeding species and regularly roosts on the moors. A grounded adult with an injured wing was seen on 6th February.

Surveys were conducted on nights between 1st June to 8th June and 3rd July to 13th July. The whole of the moors was covered in a single night on 3rd June and 8th July. This revealed a total of 30 males, which is a further reduction in numbers (SH et al). Management work of raising water levels in the interior over the last few years may be partly responsible for dropping numbers, though new habitat for European Nightjars has been created in the drier southern areas of Thorne Moors. First and last dates were 13th May-8th September.
Common Swift Apus apus

Rufous Nightingale Luscinia megarhynchos Amber List
A species more often heard than seen, and once they have young and stopped singing it can be difficult to know if they are still present. Isolated males seem to sing the least, and these may only be recorded once or twice in the early part of the breeding season; another possibility is that some males do not find a mate and move to other areas, perhaps beyond the moors. The highest day count was eight on 29th April, with seven at Will Pits and Crowle Moor and one in the colliery area. Area maxima were: Will Pits (four plus), Crowle Moor (three plus), colliery area and Green Belt (three), Elmhirst Wood (one), Goole Moor (two). This gives no more than 13 males holding territory. Breeding birds were observed at a site very close to where the nest described last year was, and their progress was followed from 16th May. The pair was seen carrying food for young on 24th May and a nest containing four unfledged young was found about 30 cm up in Rhododendrons Rhododendron.

By 26th June there were well grown juveniles in the nest. On 4th July a second nest was found in this area (along Fisons’ Road), and it contained five juveniles. The third pair in this area was unsuccessful possible due to the unwelcome attentions of a pair of Carrion Crows that had a nest nearby. Blackwater Dyke: A pair was feeding young here on 10th, 25th and 28th June. The maximum day count of adults was five (four males and one female) along Fisons’ Road on 13th May.
