Lower Derwent Valley NNR - May Sightings
May is often an exciting month in the valley and this year
it certainly didn’t disappoint. The month opened with at least two, possibly
three Great White Egrets amongst the large numbers (up to 50+ and 12
pairs) of the smaller Little Egret. A White Stork may have been of
dubious origin, however it was a fine sight nevertheless as it patrolled the
shallows around the edge of North Duffield Carrs on the 2nd and drew
an admiring local crowd. The same site continued to host a confiding pair of Garganey
in front of the Geoff Smith Hide (before moving infront of Garganey Hide having
finally read the script), whilst several other individuals were still present and
showing well at Wheldrake Ings, Bank Island, the Low Grounds, Aughton Ings and
Thornton Ings throughout the month – one of the best showings in several years.
At least nine drakes and a minimum of five females were present around the
reserve.
A Sandwich Tern that lingered for the day on the 7th
was well received by local birders, and may well have been bird of the month
was it not for the brief appearance of a White-winged Black Tern at Bank
Island on the 20th – although sadly only seen by one observer. The
first Corncrake of the year turned up on the 9th infront of
the Geoff Smith Hide at North Duffield Carrs and called for the rest of the
month – and even showed itself on occasions to a few of the 400+ observers who
are estimated to have enjoyed the sound of this bird rasping from the meadows.
Seven other calling birds were located during the month with three Spotted
Crakes also present along with the first returning Quail. Hobbies
had a great month with up to eight over Wheldrake from mid-month and with possibly
up to 16 around the whole valley.
Other records of additional interest included 3
lingering Whooper Swans, an Arctic Tern on the 8th, a Common Crane until mid-month (with
another flyover), and two first summer Little Gulls on the 20th.
Wader passage included three Dunlin, 7 Ringed Plover, two Green
Sandpiper, a Wood Sandpiper (3rd-6th) a Turnstone
(7th and 28th) and two Bar-tailed Godwits (11th).
Several parties of Black-tailed Godwits continued to pass through the
site with at least one pair lingering during the month, along with seven
lekking Ruff. Breeding wader numbers were promising with 67 drumming Snipe
recorded and enjoyed by many whilst listening out for the Corncrake at North
Duffield Carrs at dusk. A Turtle Dove over Bank Island on the 7th
was also notable.
As not to be out done by the birds some notable
mammal sightings were logged including two Fallow Deer at Bank Island on
the 8th with a single there on the 18th. A Badger
made a quick dash the full length of the Wheldrake meadow in daylight on the 11th,
where the first Roe Deer fawn was recorded on the 10th. As
expected the number and varity of insects increased during the month with a now
annual sighting of two Hairy Dragonflies (Wheldrake and Skipwith) on the
18th.
Many thanks as always to everyone who has submitted records throughout the month, in particular to regular valley birder Duncan Bye, and thanks also to everyone for the use of their photographs - Duncan Bye (DB), David Gilfillan (DG), Jono Leadley (JL), Terry Weston (TW).
