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 - March Sightings


One of the two wintering drake American Wigeon remained until at least the 24th and proved popular with visiting birders on its chosen pond at East Cottingwith. The drake Ruddy Shelduck remained at Bank Island on the 1st and 2nd before relocating to North Cave Gravel Pits. Over 832 passage Whooper Swans were recorded throughout the month, although this figure is more likely to be in excess of 100 with uncounted passage herds noted after dark. Over 2,000 Pink-footed Geese lingered in the area until late in the month with nine White-fronted Geese appearing as part of a wider displacement. The first returning Garganey was reported (22nd) with numbers up to three a few days later (26th), the latter date also brought the first Mandarin of the year to Bank Island. Several grounded Common Scoter were noted towards the second half of the month with a concentrated period of nocturnal passage on the 24th and 25th as birds moved across country on their spring migration. Bitterns were noted on the 3rd and 20th, whilst three Great White Egrets and ten Common Cranes were logged during the month. The first returning Osprey also appeared (5th) and a female Merlin was reported at Bank Island (6th).

The first returning Little Ringed Plover was recorded on nocturnal passage on the 20th, whilst the spring passage of Black-tailed Godwits increased from 500 on the 1st to 911 on the 14th (250 remained at month end but with a degree of turnover during the month). The first chipping and drumming Snipe were noted on the 3rd when 30+ Jack Snipe were recorded at Bubwith Ings. Green Sandpipers were present on the 11th and 27th.

The first returning migrants included Chiffchaff (4th), Sand Martin (15th), Willow Warbler (24th), Blackcap (25th), and Swallow (30th).

Many thanks 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 Bye, Gary Flakes and Trevor Walton for the use of their images below.
