Welcome to the LDV NNR ringing blog, this blog is designed to share the experiences, findings and tales from a group of dedicated ringers. We specialise in conservation orientated research projects, largely focusing on wildfowl, waders, owls and birds of conservation concern, in and around the Vale of York NNR's.

NB - Whilst the purpose of this blog was initially designed to cover our nationally important wildfowl ringing activities, it now also features wildlife and work posts, explaining how we manage the NNR for both wildlife and people.

Lower Derwent Valley NNR Sightings - October

Early flooding saw a rapid build-up in wintering waterfowl in a month that certainly delivered plenty for the local birders. 181 Whooper Swans moved through the site in addition to the build-up of 70 resident wintering birds, whilst nearly 6000 Pink-footed Geese moved over during the course of the month, presumably linked to the record numbers present on the Humber. A large build-up of 1800 Greylags attracted other species including 13 Barnacle Geese and 17 Egyptian Geese (including a late brood of three). Wigeon and Teal numbers exceeded over 3000, with deep water also attracting an early high count of 173 Tufted Duck and 43 Pochard, along with 154 Gadwall, 130 Shoveler and 111 Pintail. Highlights included an all too brief Ring-necked Duck (10th), Scaup (13th-15th and 23rd) and the earliest ever Smew, a redhead from the 16th-27th. Two records of Little Egrets were far out-numbered by their larger cousins, with up to five Great White Egrets lingering in the second half of the month – a new reserve record.



Raptor watchers were spoilt with up to eight Marsh Harriers roosting in the valley, with a juvenile Hen Harrier present at Wheldrake (10th-19th) and another in the wider area (28th). The last Hobbies (11th) overlapped the first returning Merlin (9th) whilst 16 Kestrels and 34+ Buzzards were counted during the monthly WeBS on the 12th.


Wintering wader numbers also increased with 2450 Lapwing and 2100 Golden Plover recorded. Up to 325 Snipe were counted as well as up to 16 Jack Snipe, which included a noteworthy total of 10 that were caught and ringed. Up to 52 Ruff had returned late in the month, with a single Black-tailed Godwit (20th) and Spotted Redshank (27th) appearing with the first returning Redshank. A lingering Greenshank was present until the 17th with two Green Sandpipers recorded until the 20th.
Outgoing migrants included the last Reed Warbler and Whitethroat (2nd and 3rd respectively), Chiffchaff (15th), Blackcap (16th) and the last two Swallows (27th). These were increasingly replaced by up to 16 wintering Stonechat, the first Redwing and Fieldfare on the 2nd and 3rd (large arrivals of 2000+ on the 20th), with seven Bearded Tits (5th), three Cetti’s Warblers and two lingering Ravens also being notable.
Many thanks as always to everyone who contributed records throughout the month, in particular to members of the YOC, and thanks also to Duncan Bye, Gerry Capelin, Matt Gowney and Jono Leadley for the use of their photographs.
