RECENT DEVELOPMENTS IN VERTEBRATES RECORDING
Some time ago, following discussion within the Thorne & Hatfield Moors Conservation Forum, it was considered that greater survey effort should be encouraged on the herptiles of these moorlands. For Thorne Moors, the only relevant recent published item was a note on the newts by Martin Limbert and Bryan P. Wainwright, which appeared during 2003 in the Forum journal, Thorne & Hatfield Moors Papers. As a result of the discussion, the new momentum extended to the drafting of a similar note on the anurans and an allied paper on the fish fauna of the area. However, this interest subsequently evolved into a full review of the fish and all herptiles, which appeared as a THMCF Technical Report in 2004, written by ML, BPW and Steve Hiner. During the work on this, a companion review of the mammals of Thorne Moors was also deemed worthwhile and timely. This was compiled by ML, being published - again as a THMCF Technical Report - in 2005.
During 2004, BPW relinquished his unofficial post as Thorne Moors vertebrates recorder (alongside the reptiles recorder, SH), prior to leaving for South America. His duties had mainly comprised the production of a yearly bird report, printed by English Nature. The recording baton was grasped by ML, who decided that a full review of vertebrates recording was overdue. This resolved into five aspects:
1. The production of a published annual report covering all vertebrate groups, not just birds. The first Thorne Moors Vertebrates Report embraced 2004, and appeared under the aegis of the THMCF. That for 2005 is necessarily produced independently.
2. A compilation of a summary of all existing records of fish and herptiles (21 spp.), plus a short associated history of recording and a bibliography. This was already newly available as THMCF Technical Report No. 13, amounting to 36 pages.
3. As 2, covering all mammals (37 spp.). This now forms THMCF Technical Report No. 15. It comprises 49 pages, plus an unpublished supplement (three pages) giving the entire Badger script, which was not published in full for security reasons.
4. As 2, covering all birds (230 spp.).
5. The creation of a map of place-names used for vertebrates recording on and about Thorne Moors since 1966. This is now issued with the Thorne Moors Vertebrates Report 2005, and lists upwards of 160 names. 
Thus, during 2004-05 four of the five identified components of the review of Thorne Moors vertebrates were completed, but leaving the largest, a summary of the birds, as a future target. Inevitably, this latter will be a significantly larger task, involving very many records for four times more species than there are of other Thorne vertebrates. For any future overall documentation of the vertebrate fauna of Thorne Moors, there is now a firm and accessible basis of knowledge for the mammals and cold-blooded species, allowing emphasis to be transferred to the avifauna. To this end, collation of ornithological data will commence in 2007, and will probably be a protracted exercise. In addition to bird records and allusions extending back to the eighteenth century, modern recording and research commenced in 1966, and has been continuous since then, giving a mass of data for a period now extending over 40 years.
1. Parameters of conservation. Thorne Moors lies within the Humberhead Levels Natural Area, and the peatland and contiguous wetlands comprise the Thorne Moors Site of Special Scientific Interest. The moorland forms a component of the Humberhead Peatlands National Nature Reserve, managed by Natural England and (in the North Lincolnshire section q.v.) the Lincolnshire Wildlife Trust. The NNR has international designations to recognize its conservation importance.
2. Recording area. For vertebrates 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.
3. Place-names. In broad terms, the name Thorne Moors is used to embrace both the peatland and the 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 vertebrates recording. These names have been derived, since 1966, from Ordnance Survey maps, the former peat industry, NCC/English Nature and local birders. A place-names map has recently been compiled, and is issued with this report.
4. Current sources of nomenclature and species sequence. In this report, English and scientific names and sequence of species accord (where appropriate) with the following:
Beebee, T.J.C. and R.A. Griffiths (2000) Amphibians and Reptiles. A Natural History of the British Herpetofauna. The New Naturalist No. 87. London: HarperCollins Publishers.
The British Birds List of Birds of the Western Palearctic; see www.britishbirds.co.uk/bblist.htm (accessed 31st January 2006).
Arnold, H.R. (1993) Atlas of mammals in Britain. Institute of Terrestrial Ecology Research Publication No. 6. London: HMSO.
In addition, botanical nomenclature and sequence follow:
Stace, C. (1997) New Flora of the British Isles. Second edition. Cambridge: Cambridge University Press.
5. 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 Ornithological Section Reports Committee or the Lincolnshire Bird Club, as appropriate. Advice and blank forms can be made available upon request.
6. 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.
7. Daily counts. In the species accounts which follow, there are 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.
VERTEBRATES RECORDING IN 2005
1. Statistics for 2005. During the year, two species of amphibian, three species of reptile, 128 species of bird and 11 species of mammal were reliably reported from Thorne Moors. There were no additions to the existing lists, although rarely reported species like Red Kite, Kittiwake and Firecrest were met with. There were also some useful breeding records, the most outstanding being a Common Quail with chicks. The overall number of records fell again. My own fieldwork was limited in 2005, especially in the second half of the year. Unfortunately, this pattern was more generally repeated, with coverage of the autumn bird migration being very inadequate.
2. Publications, reports, etc. The following references appeared during 2004-05, using vertebrates data concerning Thorne Moors, but not necessarily relevant to those years.

Common Frog Rana temporaria.. An immature was present at Ink1e Moor Pond on 1st July (CW).
Common Toad Bufo bufo. An immature was uncovered on 7th February during work on the base for a wind turbine at English Nature’s depot at Will Pits Scrape (SH).
Viviparous or Common Lizard Lacerta vivipara. There were occasional (but sometimes vague) records of singles spanning 3rd March (Rhododendron Path) and 26th September (‘Middle Moor’), with other locations including Collis’ Tram, Elmhirst Tram, Will Pits Scrape and the Viewing Platform. Larger counts were obtained from the Southern Canals, with June totals of 2 along canal 6 (western side) on 27th and 4 along canal 5 the next day. The highest count was c.5, seemingly all juveniles, along Northern Tram on 29th August.
Grass or Ringed Snake Natrix natrix. One was seen along the colliery road on 22nd April (WHP).
Adder or Northern Viper Vipera berus. Recorded from 8th March, always singly, and with few records after 8th August. Locations were the Whaley Balk/Rhododendron Path area, Green Belt area (including map reference c.SE714163), the Paraffin Cuttings, the Viewing Platform, the site of Blue Bridge, and the track along Swinefleet Line Dyke. This latter was the locality of the last, a male on the significantly late date of 11th October (SH).
Mute Swan Cygnus olor. The single record was of 2 at Will Pits Scrape, which departed to the east, on 19th November.
Bewick’s Swan C. columbianus. Eight were at Will Pits Scrape on 14th October (SH).
Whooper Swan C cygnus. Reported on three dates: 7th February (28 at the flooded workings), 16th April (16+ north) and 14th October (4 east).
Pink-footed Goose Anser brachyrhynchus. There was movement on 1st January, involving skeins of 26 (west), 72 (south-west), c.100 (north-west), 51 (west), 69 (west), 110+ (west) and 100+ (south), giving a total of 528+. The only other record in the early months concerned 2 at the flooded workings on 22nd April. Remaining records were obtained from Will Pits Scrape in mid-October. On 14th, 50 were with 100+ Greylag Geese, eventually flying off south-east, and 1 was with 300+ Greylags the next day.
Greylag Goose A. anser. The first of the year appeared on 13th March, when 2 pairs were at Will Pits Scrape and what may have been a different 4 flew over the Moors. There were also 4 on 1st April, and then subsequent records to 19th November, when 20 were at Will Pits Scrape. Few counts exceeded 40+, but on 20th September a "large group" was at Will Pits Scrape, and this location held up to 300+ in October (on 7th/15th). Two adults and 7 juveniles were at the flooded workings on 25th June, but with only 6 juveniles the next day, and there were no other indications of breeding. The waters named were the only ones attracting Greylags. Of 6 seen on 12th May, one had dilute plumage.
Greater Canada Goose Branta canadensis. At Will Pits Scrape, there was 1 on 28th May and 23+ on 15th October.
Common Shelduck Tadorna tadorna. Reported on 1st January (3), 13th March (1), 25th March (2), and from 16th April-28th May. Counts during this latter period reached 7, plus 10 on 28th May. Most birds were seen at the flooded workings, but occasionally at Will Pits Scrape.
Eurasian Wigeon Anas penelope. Only seen in October, beginning with c.50 at Will Pits Scrape on 7th, 1 there on 15th, and 2 at the flooded workings on 30th.
Gadwall A. strepera. Eight were at the flooded workings on 1st January. Subsequently encountered only in the first half of the year, commencing with a pair on 25th March. Peak counts occurred in May, with 10+ on 2nd and 6+ on 5th. Mainly a denizen of the flooded workings, but also present at Will Pits Scrape and Green Belt Scrape. On 12th May, a pair was flushed from Mill Drain.
Eurasian Teal A. crecca. Daily counts were generally lower than in recent years, with few exceeding 23. Apart from 100+ on 1st January, the maxima occurred in September-October. These peaked at 300+ in September (21st) and c.400 in October (30th). Breeding was proved, with 2 females accompanied by young on 20th July. Eurasian Teal were pursued unsuccessfully by a male Peregrine Falcon on 2nd October.
Mallard A. platyrhynchos. Few significant counts were submitted, with the highest during September-December. These reached 280+ in September (21st), 300+ in October (15th) and c.200 in December (10th).
Pintail A. acuta. The flooded workings held 2 males and 2 females on 21st September, 22+ on 14th October, and 2 males and 8 females the next day.
Shoveler A. clypeata. The flooded workings held 2 males and 1 female on 1st January. On 12th February, 6 males and 2 females were at the flooded workings, with a further male on Goole Moor. These workings, Will Pits Scrape and Green Belt Scrape attracted Shovelers from 25th March, with occasional birds in flight elsewhere. Daily totals exceeded 6 in May (10+ on three dates), August (25 on 18th), October (15+ on 15th) and December (15+ on 10th). Four adults and a brood of 3 young were seen at the flooded workings on 26th June (AS).
Tufted Duck Aythya fuligula. In January, records were obtained on 1st (2 males and 1 female at the flooded workings) and 31st (4 at Will Pits Scrape). These were followed by 2 males and 1 female at the flooded workings on 13th March. Subsequent records were restricted to April-May, beginning with 12+ at the flooded workings on 1st April. These workings and Will Pits Scrape were the only locations reported, with maxima of 4 males and 1 female at the former on 12th May, and 4
pairs at the latter on 2nd May. In this month, the day’s total on 2nd was 10 birds, and there was a combined count of 7 males on 12th.
Ruddy Duck Oxyura jamaicensis. The only pre-April record was a male at the flooded workings on 25th March. Reported regularly from 1st April at Will Pits Scrape and the flooded workings, with the first female (at the flooded workings) on 16th April. May details included a combined total of 8 males and 2 females on 5th, the respective yearly maxima for each sex. Evidence of breeding involved a female with 4 young at Will Pits Scrape on 24th July, which proved to be the last date of the year.
Red-legged Partridge Alectoris rufa. On 13th May, a single was seen between Red House Farm and Top Moor Farm.
Grey Partridge Perdix perdix. There were few records, with none of them remarkable except along Will Pits Tram. Here, an adult and 2 immatures occurred on 24th July, and the year’s maximum, of 4, was obtained on 20th September.
Common Quail Coturnix coturnix. On 24th July, an adult and at least 5-6 recently hatched chicks were encountered along a track at map reference SE735164 (PH). A notable addition to the breeding list.
Common Pheasant Phasianus colchicus. Daily counts reached 22+ (29th August). Breeding proved.
Little Grebe Tachybaptus ruficollis. Records were obtained from the Paraffin Cuttings (singles), Will Pits Scrape (singles), and the flooded workings (maximum 4), beginning on 25th March. Of these three waters, only at the latter workings were records obtained after May. These included the maximum (4 on 18th August), the only evidence of breeding (2 adults and 1 juvenile on 26th June), and the latest (3 on 27th September). An additional site was Bell’s Pond, where singles occurred on 15th October and 10th December.
Great Crested Grebe Podiceps cristatus. Singles were at Will Pits Scrape on 1st January and 20th May.
Black-necked Grebe P. nigricollis. The first were single grebes at Will Pits Scrape on 29th March and several dates in April. Two were present at the flooded workings from 16th April. Here, there were then 4+ on 2nd May, on which date there were also 3 at Will Pits Scrape (WHP, KB). Subsequent May records included maximum counts of adults at Will Pits Scrape of 3 on 5th/10th/14th, 4 on 20th/28th, and 6 on 12th (ML). On 17th May, a pair had a small juvenile at this water (RB). At the flooded workings, May totals decreased to 2 on 20th and 1 on 24th. Here, records in June-July occasionally involved 1 bird, but with 2 on 28th June/3rd July, and 3 on 26th July, with the final grebe here on 2nd August. At Will Pits Scrape, June sightings included 3 on 2nd and 2 adults and 2 juveniles on 25th (WHP). Here in July, records were obtained on 3rd (2 adults), 7th (2 adults and 1 juvenile), 21st (2 adults and 2 juveniles), 26th (3 adults and 2 juveniles), and 30th (2 adults and 2 juveniles). Two adults and a "fully grown" juvenile were observed on 2nd August, with further records during the month of 1 adult and the juvenile on 9th/12th/19th. Interchange of adults between Will Pits Scrape and the flooded workings is likely, with the largest daily count combining both areas being 7 on 2nd May, and with the highest total at one water being 6 at Will Pits Scrape on 12th May. However, there is evidence of only 1 pair hatching young, at Will Pits Scrape, and of these latter, only 1 was apparently reared. In addition, an adult at Will Pits Scrape on 24th July was in almost full winter plumage (PH). In view of its advanced moult, perhaps this grebe was a transient failed or non-breeder.
Great Cormorant Phalacrocorax carbo. Passing birds were seen on 2nd May (2 east), 28th May (3 east), 27th September (l west) and 15th October (l north).
Grey Heron Ardea cinerea. Occasionally flew over the moorland edge or adjacent fields, or was flushed from peripheral drains. There were no records during May-late August.
Red Kite Milvus milvus. One reportedly flew over Crowle Moor on 19th June (per Bird Watching).
Marsh Harrier Circus aeruginosus. Individuals variously described as females, ‘creamcrowns’, immatures and ‘brown’ birds were recorded on 1st January (l immature) and 13th March-7th November, usually singly, but 2 on dates during July-September, on 2nd/14th October and 7th November. In addition, there were c.5 on 30th August and 3 on 13th October. Single males appeared from 22nd April-20th May, on 24th June, and from 21st September-13th October. A pair was displaying over Will Pits Scrape on 22nd April (WHP).
Hen Harrier C. cyaneus. On 1st January, sightings involved a ‘ringtail’ and then a male over Mill Drain Marsh, with the latter landing there at 15.05hrs (to roost?). The only other records until October were singles on 31st January and 9th September. There were October records from 2nd, of singles except 2 on 29th. All sightings were of ‘ringtails’ except the male on 1st January and another on 27th October.
Eurasian Sparrowhawk Accipiter nisus. Recorded throughout the year except June-July, involving up to 3 birds, these latter on dates in March and on 1st April. March records also included a pair over Green Belt on 13th/18th. On 26th June, 1 carried prey into Will Pits.
Common Buzzard Buteo buteo. Singles passed overhead on 25th March, 21st April, 2nd May, 18th August, 22nd September, 27th September and 2nd October. They occasionally attracted the attentions of Carrion Crows, and of a Marsh Harrier on 18th August.
Common Kestrel Falco tinnunculus. Daily totals exceeded 3 on dates in August-November, maximum 6 on 21st August.
Merlin F. columbarius. Reported only on 18th August, when 2 males were over the flooded workings and the Shoulder o’ Mutton, with 1 later perched at the flooded workings east of Mill Drain Marsh.
Hobby F. subbuteo. Extreme dates were 27th April-13th September, except for 1 on 27th October (RA). Almost always reported singly. However, there were 2 on 29th April/26th June and occasionally in July, plus 3 on 2nd/13th May and c.5 on 30th August. All specified birds were adults, except a first-year on 26th June and an immature on 19th August.
Peregrine Falcon F. peregrinus. A female was seen on 13th March, attempting to catch a Carrion Crow. There were also occasional records of a male in the early months, last date 10th May, when it successfully captured a Blackbird. A male was also seen on 24th June (SH). Subsequently, recorded in August on 18th (adult male), 21st (adult male stooping after a Common Snipe), 22nd (adult and immature males) and 30th (2 adults and 1 immature). Single adult and immature males occurred on 22nd September. A few days later, on 27th, the adult male was watched mobbing an immature Marsh Harrier. The immature male was encountered again on 2nd October, when unsuccessfully hunting Eurasian Teal. Records in late October involved an adult male and (on 27th) both immature and adult females. The male was then infrequently present to the end of the year.
Water Rail Rallus aquaticus. Recorded irregularly and singly, except for 2 on 25th March, 18th August and 19th November. There were no records between 2nd May-18th August, on which latter date 2 at the flooded workings called frequently and gave good views. Reports were scattered, and comprised Durham’s Garden, Green Belt Scrape, the Canals, ‘Middle Moor’, the Viewing Platform, Will Pits Scrape and the flooded workings.
Moorhen Gallinula chloropus. No counts exceeded 10. Breeding proved.
Common Coot Fulica atra. Reported from the flooded workings and Will Pits Scrape during March-May. In the latter month, maxima were 3 at Will Pits Scrape (2nd) and 5 at the flooded workings (12th/15th).
Oystercatcher Haematopus ostralegus. On 27th April 1 was at the flooded workings, with a second on 14th May which departed eastwards.
Little Ringed Plover Charadrius dubius. A pair bred, being present from 16th April. Four eggs were laid, which had hatched by 25th May. Two juveniles and an adult were seen in June to 23rd, the last date. One was at the flooded workings on 9th May, possibly an off-duty parent.
Ringed Plover C. hiaticula. Six flew north over Fisons’ Road North on 12th May. Others were present at the flooded workings on 24th July (1), 18th August (6), 21st September-1st October (maximum 5, on 21st-22nd/27th), and 7th/15th October (singles).
European Golden Plover Pluvialis apricaria. There were up to 3 overhead on three dates in March/October, and c.200 in fields at Tween Bridge Moor on 19th November.
Grey Plover P. squatarola. The flooded workings attracted singles on 2nd May and 15th October.
Northern Lapwing Vanellus vanellus. Recorded throughout the year except November-December. At the flooded workings, resident from 25th March-15th October, with 8+ on the first date and 60+ on the last. Here, May counts reached 10 on 12th (including the Shoulder o’ Mutton area). During August-October, they exceeded 60+ in August on 18th (c.590) and 21st (c.545). In addition, on 21st September, 700+ flew over fields east of Crowle Moor.
Little Stint Calidris minuta. Three were present at the flooded workings on 21st September.
Dunlin C. alpina. Observed on 12 dates during July-October, with one exception all being from the flooded workings. The first were 7 on 24th July. August records were obtained on 18th (8), 19th (6) and 28th (1). In September, the relevant dates were 21st (11), 22nd (17), 27th (c.40 flushed by a male Eurasian Sparrowhawk) and 30th (30+ heading north). There were 24 on 1st October, then 1 on 7th and 4 on 14th-15th.
Ruff Philomachus pugnax. At the flooded workings in August there were 4 on 18th, 2 on 19th, and 1 disturbed by a Marsh Harrier on 21st.
Jack Snipe Lymnocryptes minimus. One was flushed near the Viewing Platform on 14th October.
Common Snipe Gallinago gallinago. Most reports came from the flooded workings, with no counts in the early months exceeding 4 (on 1st April). May-July records involved a ‘chipping’ bird at the Northern Canals on 2nd May, 1 at the Shoulder o’ Mutton on 9th May, 1 ‘drumming’ in the Canals area on 26th June, and occasional singles at the flooded workings in July. There were several August records, maximum 5 at the flooded workings on 18th and 10 in the Mill Drain Marsh-flooded workings area on 21st. A male Peregrine Falcon stooped after a Common Snipe on this latter date. At these workings in September, 1-2 were eclipsed by 10 panicked by Marsh Harriers on 20th. October counts reached 14 on 6th, then with fewer records to the end of the year, peaking at 6+ on 15th October.
Woodcock Scolopax rusticola. Occasional singles were flushed in January, March, October and November. In addition, breeding was proved at Cassons, with 3 juveniles on 26th July (RA). 2004: Also noted from the Southern Canals on two dates in July.
Eurasian Curlew Numenius arquata. Present during the period 25th March-23rd May, with 2 birds noted. In addition, 1 was at the flooded workings on 18th August, 1 flew south on 21st August, and 1 headed north on 15th October.

Greenshank T. nebularia. The flooded workings attracted singles, on 3rd May and in August occasionally from 18th. Also 4 on 9th September. The last of the year passed south-west on 27th September.
Green Sandpiper T. ochropus. Noted 24th July-21st September, mostly 1 or 2 at the flooded workings and Green Belt Scrape. One was at Jones’ Cable on 18th/21st August, 4 were flushed from Green Belt Scrape on the latter date, and 4 were in the Northern Canals area on 9th September.
Common Sandpiper Actitis hypoleucos. The flooded workings attracted singles on 5th May and 24th July.
Black-headed Gull Chroicocephalus ridibundus. Spring counts of breeding birds at Will Pits Scrape reached 216+ on 13th March, c.400 on 1st April, c.600 on 16th April, and c.500 on 2nd May. On the latter date, sitting birds were observed, their nests formed on tussocks of Soft-rush Juncus effusus. Chicks were apparent from 20th May, with 200+ young on 25th June. At the flooded workings, after 160+ on 13th March, there were 200+ on 1st April, 400+ on 16th April, and c.300 on 13th May. Nesting birds were again evident from 2nd May, with c.60 chicks on 28th May.
Common Gull Larus canus. Very few reported, all overhead, with none notified from MayNovember. The maximum was 4 on two dates in March.
Lesser Black-backed Gull L. fuscus. Recorded mostly during April-September at the flooded workings, sometimes grounded, maxima being up to 60+ in May (on 20th), with counts in other months not exceeding 10 except 24 on 27th September. On 29th August, 25+ trickled south-west over Crowle Moor. The latest record was 10 at the flooded workings on 14th October.
Herring Gull L. argentatus. None documented during June-August. Occasionally flushed at the flooded workings in May (maximum 4 on 2nd), and here in October-November counts reached 20+ on three dates.
Great Black-backed Gull L. marinus. As with the preceding species, none was reported during June-July, and in August only on 18th (3 west). In the first half of the year, counts at the flooded workings infrequently reached 14 (on 16th April), and there were c.50 at Green Belt Scrape on 14th May. The flooded workings attracted up to c.80 in October (on 14th), but only 10 in NovemberDecember.
Kittiwake Rissa tridactyla. On 1st April, an adult flew off east from Will Pits Scrape (WHP).
Common Tern Sterna hirundo. On 2nd May 1 flew east over Green Belt, as did another south on 25th.
Rock Dove Columba livia. Records of feral birds at Thorne Colliery included c.30 on buildings on 12th May.

REQUESTS FOR INFORMATION
Since 1998, Black-necked Grebes have occurred on Thorne Moors, with confirmed breeding from 2001. All records are requested of this species, giving as much information as possible, including behavioural data.
In recent decades, Red Deer have been encountered on Thorne Moors since the 1960s, and there has been a continuous presence from 1994. The maximum count on and around Thorne Moors was obtained in 2004, when 35 head were seen on one date, presumably representing a large percentage of all Red Deer resident on that day. It is believed that the change in status of this species is largely allied to the regional growth of deer farming, with resultant deer at large in the countryside. In the Thorne Moors area, Red Deer may now be watched in fields and on the moorland, especially in the Will Pits area. All records of Red Deer, past and present, are being collated for population monitoring and possible future analysis. Accordingly, as much detail as possible is required when documenting Red Deer.
