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, regular readers may have noticed the increase in posts detailing wildlife found across the valley (ranging from plants, fungi, butterflies, dragonflies & other invertebrates). Ringing posts will hopefully resume over the winter months, and will run alongside wildlife and work posts.

Lower Derwent Valley NNR - January Sightings

A great start to the year and another superb month for wild geese, perhaps attracted by the huge numbers of wintering Greylags. Although mobile and at times difficult to track down (a real goose chase) there were up to 200 Pink-footed Geese, 15 Tundra Bean Geese and at least 53 European White-fronted Geese early in the month, along with Egyptian and Barnacle Geese also being recorded around the valley. In addition to the geese, up to 100+ Whooper Swans were present along with two returning Bewick’s Swans and large numbers of wintering ducks, including 250+ Pintail, two Scaup and a Red-breasted Merganser.

The Wheldrake gull roost and day time feeding sites around the landfill site at Rufforth on the outskirts of York provided a lot of interest as gull numbers soared throughout the month. Amongst the 20,000 large gulls, up to five first-winter Glaucous Gulls were found (including a single rehabilitated bird ringed and released there on the 6th), up to four Iceland Gulls and a single Caspian Gull, whilst two Mediterranean Gulls were also recorded on the Ings during the roost. Another feature of the month was the above average number of calling Water Rail present around the site (at least 16) and Woodcock – with several noted coming onto the Ings after dark to feed.

Up to three Stonechat re-appeared during the month having survived the freezing cold spells, whilst the same conditions possibly accounted for a handful of Waxwing appearing around the valley at Canal Head and in Wheldrake/Thorganby.

Away from the birds a single Muntjac Deer captured on the camera trap at East Cottingwith on the 5th was the first to be confirmed in the area, whilst a single Kidney-spot Ladybird was rather early at Wheldrake Ings on the 25th and unsurprisingly the first record of the year.

On the ringing front the year got off to a good start with stable water levels, continued feeding and cold weather conditions. A total of 124 mixed Teal, Wigeon and Mallard were whoosh netted at Bank Island during the early part of the month, followed by two successful cannon net catches which resulted in a further 91 Teal, 60 Wigeon and 6 Pintail. Whoosh netting at both Bank Island and North Duffield Carrs resulted in further birds being added and a total of 366 ducks ringed during the month. The rehabilitated Glaucous Gull released at Harewood Whin by Jean Thorpe was the first to be ringed in the area

Many thanks as always to everyone who has contributed records throughout the month - especially members of the YOC and the regular valley birders, and thanks also to the following for the use of their photographs - Duncan Bye (Dunlin), Ian Harrison (Waxwing) and Terry Weston (Kingfisher).
