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 - January Sightings


It’s been a fantastic start to the year with a total of 129 species recorded during the month (compared to 119 in January 2025).

The juvenile White-tailed Eagle remained throughout the month until the 28th attracting large numbers of admirers from near and afar, and was undoubtedly the highlight of the month. Other notable sightings included two Glossy Ibis (2nd), up to six Twite (from the 4th) in the wider area at Dunnington (with mixed finches) and a Long-tailed Duck at Hemingbrough (25th-31st).

Otherwise it was a great month for geese following a national influx from the continent, with 3,000 Greylags, 28 White-fronts, 19 Tundra Beans, 2,000 Pink-footed and 7 Barnacles, whilst amongst the ducks three Scaup lingered for most of the month, a single red-head Smew was present late on, and four Common Scoters were notable. Three Common Cranes were at Ellerton on the 31st

Raptors were once again well represented with up to four Merlins, 13 Marsh Harriers and five Short-eared Owls. The now usual early spring build-up of Black-tailed Godwits continued with 248 present late in the month, whilst a single Bar-tailed Godwit and Spotted Redshank appeared to be wintering along the riverbank, and a single Green Sandpiper make a brief appearance on the 2nd. Two Mediterranean and three Caspians Gulls were present throughout the month with a Water/Rock Pipit seen on the 11th. Fifteen wintering Blackcaps and a minimum of four Chiffchaff were also noted.
