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.

May

Lower Derwent Valley NNR Sightings - May 2015

May turned out to be a rather quiet month on the bird front, with many species busy getting on with the breeding season, and due to a lack of standing water spring passage was limited. The last few signs of winter included a lone Pink-footed Goose at Wheldrake Ings until the 12th and the last lingering Pintail until the 19th, whilst a showy drake Garganey at Bank Island early in the month gave a more seasonal flavour. A Great White Egret (an annual visitor in recent years) flew over Bank Island on the 15th whilst up to five Little Egrets were present in the same area on the 14th, with one pair lingering until the end of the month. Up to 28 pairs of Grey Herons were nesting in the local heronry with a total of 21 chicks colour-ringed there on the 27th

A pair of Red Kites attempted breeding but appeared to move on after nest building - much to the relief of the herons who had their first clutch of chicks predated on by the pair. An Osprey flew north on the 25th, the only record for the month. Surprisingly there was only one sighting of a Marsh Harrier during the month, a single at Wheldrake Ings on the 2nd, but several Hobbies and a single Peregrine remained throughout the month.

Last month’s Common Cranes remained in the valley on the 1st and 2nd, while the 1st also saw two Avocets and a Sanderling at Wheldrake Ings. Otherwise passage waders were rather disappointing with seven Dunlin on the 6th and a handful of Greenshank being the only highlights outside of the usual spring roost of Whimbrel, which peaked at 123 on the 1st, with 31 remaining on the 10th. Several roding Woodcock were recorded on Skipwith Common (a noticeable increase in recent years) and several broods of Lapwing, Redshank and Oystercatchers were located during the month. Tern passage was similarly restricted with a total of eight Arctic Terns logged on two dates, and two pairs of Common Terns were present throughout the month on the tern rafts provided.

Arriving migrants included the first Turtle Doves of the year on the 1st and 2nd, a Blue-headed Wagtail at East Cottingwith with a Wheatear on the 5th, a large arrival of Swifts between the 6th -10th, and single Spotted Flycatchers at Melbourne on the 20th and Skipwith Common on the 22nd. Cuckoo numbers continued to increase during the month with another noticeable arrival late in the month bringing the total to around 27 calling males throughout the wider valley area.

Many thanks to all the local birders and visitors who have submitted records throughout the month, and also to the local photographers who have sent in their photographs - Cuckoo (Mark Hughes), Turtle Dove (John Heaton) - all other photographs have been taken on site by the team.


BIRDS: 

Mute Swan – 37 non breeders were present at Wheldrake Ings early in the month in addition to the two breeding pairs. The pair at the Top Pond at North Duffield Carrs were the first to hatch with six cygnets on the 20th. The first of the two Wheldrake broods (one of seven) appeared on the 21st with a brood of five later appearing on the pool there on the 27th. 13 non-breeding birds were present at North Duffield Carrs on the 28th.

Canada Goose – Four pairs raised broods on a small pond in the East Cottingwith area during the month with other pairs scattered throughout the wider area.   

Greylag Goose – 8 pairs had a total of 63+ goslings at Wheldrake Ings on the 4th when an additional 72 non-breeding birds were present. Up to 30 birds spent the last two weeks of the month at Bank Island while other scattered pairs and non-breeding groups were present in the wider area. 

Greylag Geese - Released at NDC - 22/05

Teal – Breeding birds were scattered throughout the valley during the month. 

Wigeon – Up to eight pairs were present throughout the valley during the month.

Garganey – A drake was present at Wheldrake Ings on the 4th and 5th before it moved to Bank Island on the 8th, 9th and 10th. A pair lingered at Wheldrake from the 21st to month end. 

Mallard – Single broods (one of nine) appeared at Bank Island on the 5th, and near Melbourne on the 6th, with broods appearing from then on throughout the remainder of the month.

Gadwall – Breeding pairs were present throughout the valley. An adult male was caught and ringed in the swan pipe at North Duffield on the 14th.

Gadwall - North Duffield Carrs - 14/05

Tufted Duck – Up to 35 pairs were present early in the month with Wheldrake Ings acting as the stronghold for these birds. 

Pochard – A single drake was present at Wheldrake Ings on the 9th. 

Water Rail – Up to four calling birds were present throughout the month at Wheldrake Ings. Another single remained near Church Bridge at Melbourne on the 16th, suggesting breeding was possibly taking place at this site which has held birds throughout the winter and spring. 

Little Grebe – A single pair were present on Wheldrake Ings throughout the month, with another pair at North Duffield Carrs and East Cottingwith, the latter appearing with four chicks on the 19th. 

Cormorant – Up to 15 non-breeding birds remained at Wheldrake Ings, with feeding birds recorded regularly along the Pocklington Canal and River Derwent throughout the month. 

Grey Heron – Up to 28 nests were present in the heronry adjacent to Wheldrake Ings. Having failed on the first clutches due to presumed Red Kite predation, seconds clutches fared better with an average brood size of 2/3 chicks per each successful pair. 21 chicks were colour-ringed on the 27th when a minimum of 46 chicks were present in inspected nests. Please keep a look out for yellow darvic’ed birds and report any sightings in the logbooks in the hides – thank you.

Little Egret – One or two were present daily from early on in the month with five at Wheldrake Ings/Bank Island on the 14th, and up to three daily thereafter until at least the 20th.

A pair which had been holding territory throughout April were found to have a completed and lined nest on the 8th. However, they appeared to desert and move on after the 15th – possibly a first-time breeding attempt. 

Marsh Harrier – A single passage bird at Wheldrake Ings on the 2nd was surprisingly the only record during the month. 

Peregrine – A single immature was still present at Wheldrake Ings on the 6th and 9th, another immature, perhaps the same bird, flew over Bank Island on the 28th.

Two were at Bank Island on the 7th along with birds between there and Wheldrake Ings, and a pair near Melbourne thereafter until month end. The birds at Wheldrake Ings settled on the tern raft from mid-month and appeared to be going to nest having made a scrape by the 20th. They were sadly then evicted by a pair of Black-headed Gulls that went on to build a nest by the 24th. 

Arctic Tern – Five flew north over Canal Head at Pocklington on the 5th with three over Bank Island on the 8th. 

Barn Owl – A number of birds were present throughout the valley although sightings declined from previous months as birds returned to breeding sites.
