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 we how manage the NNR for both wildlife and people.

Lower Derwent Valley NNR - October Sightings


Although the ongoing dry conditions and the lack of water around the reserve meant there was little in the way of numbers of returning waterfowl and waders recorded, there was an interesting and varied roll call of species available for the local birders. A Rock Pipit at Wheldrake Ings on the 6th (with presumably the same bird again there on the 14th) started things off, followed by a Raven on the 8th, six Bearded Tits (10th), a Twite (16th) and yet another Great White Egret (22nd). Whilst any of those could have been up there as the highlight, it was the 27th that produced the star of the show – two adult Pomarine Skua’s seen flying over Wheldrake by a lone observer. These are only the second and third birds recorded in the valley following a single adult with ‘full spoons’ in March 1999, due to a large displacement in the North Sea at this time.

The first four returning Whooper Swans were noted on the 4th followed by 27 (inc. 11 immatures) in the local herd by the 26th. An impressive 3250 Pink-footed Geese were logged, although there was some duplication as birds were seen moving over the valley from the Humber roost sites to feeding locations. Teal numbers built up to 600 but were hard to locate on a regular basis whilst 50 Wigeon was a disappointing total. Up to four Green Sandpipers remained early in the month although just one stayed to the end of the month, whilst eight or nine Curlew roosted in the second half of the month with three returning Redshank and a single Dunlin over. The first returning Jack Snipe was logged on the 18th.  200 Lapwing and 350 Golden Plover were recorded as well below average counts. Incoming winter migrants include the first Redwing (3rd), Stonechat (4th), Fieldfare (7th) and Brambling (27th). Last dates for outward bound migrants included a late Yellow Wagtail (2nd), Blackcap (7th), Swallow (15th) and Chiffchaff (21st).  


Many thanks as always to everyone who has contributed records throughout the month, in particular to members of the YOC and regular valley birder Duncan Bye – thanks also to Duncan for the use of his photographs, credited DB.
