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 - December 2021 Sightings

For most people, the Dusky Warbler found in the reedbed at Swantail Hide at Wheldrake Ings (27th ), was considered the bird of the month - representing the first record of the species in the LDV. However, the rest of the month also offered excellent counts and a wide range of species, including increasingly difficult to connect with species - five Bewick’s Swans on the 28th were welcome, with up to 130 Whooper Swans also present. 500+ Pink-footed Geese were joined by up to seven White-fronts and a single Barnacle. Seven Smew (including a pristine drake), were possibly caught up in the same movement away from the continent. A first winter hybrid American Wigeon (amongst 9850 European Wigeon), and a Green-winged Teal (amongst 5140 Teal) were good finds late in the month, with a respectable 280 Pintail towards month end.

At least six Marsh Harriers were recorded along with two sightings of a Merlin. One of the months wader highlights were the large numbers of Lapwing present across the reserve – 7160 were observed on the 28th, with up to 5000 alone at Wheldrake Ings on several dates. Up to 1885 Golden Plover were also noteworthy, with 228 Dunlin, 45 Ruff, 21 Curlew and good numbers of Snipe, Jack Snipe and Woodcock. The Wheldrake gull roost increased up with up to 10,000 Black-headed and 3000 Common Gulls by month end, attracting at least three different Mediterranean Gulls. It was also a good month for owls, with two or three Long-eared and a Short-eared at Wheldrake, with all five owl species recorded at Bank Island/Wheldrake Ings on the 21st.

Aside from the Dusky Warbler, a single Chiffchaff and Cetti’s Warbler were present during the month at Wheldrake, with several Stonechat remaining throughout. Large flocks of Linnets were also present around the reserve, with small numbers of Brambling feeding in mixed finch flocks.

Many thanks as always to everyone who contributed records and counts throughout the month, in particular to members of York Birding and regular patch birder Duncan Bye – thanks also to Duncan for the use of his images below.
