Lower Derwent Valley NNR Sightings - July 2015
The highlight of the month was undoubtedly the discovery of a singing male Corncrake
on the 7th. A second bird was later seen, with the behaviour suggested
a breeding attempt may be taking place – although less vocal thereafter it was
still present until at least the 18th. While monitoring this
individual a single Quail was also located on the 7th with
another three calling before month end – a better showing than in recent
summers. Things were quiet on the waterfowl front as to be expected at this
time of year although a single Egyptian Goose put in sporadic
appearances during the month, and nine Little Egrets at Wheldrake/Bank Island
on the 24th probably reflected this year’s local breeding success.

Birds of prey stole the show during the month with a flurry of Red Kite records, up
to three were seen regularly following hay making tractors on the Ings in the
Wheldrake/Bank Island area. Three pairs of Peregrines are known to have
fledged six young from local pylons around the valley whilst Hobbies also
showed well – at least three but possibly up to five pairs have been present
throughout the area. A single pair of Marsh Harriers also lingered early
in the month. Returning waders arrived from early in the month with five Ruff
on the 3rd, a Common Sandpiper on the 9th, seven Black-tailed
Godwits on the 12th, a Whimbrel on the 14th,
five Golden Plover on the 25th and a Greenshank on the
26th. Up to three Green Sandpipers were also present
throughout the month with up to 24 Curlew and 400 Lapwing also
recorded.
Two pairs of Turtle Doves were confirmed to
be breeding in the Foggathorpe area whilst up to three Nightjars were
present on Skipwith Common. It was a good month for Kingfishers which reflected
a successful breeding season, an estimated six or seven breeding pairs were
thought to be present around the valley, with Wheldrake Ings and the Melbourne
area of the Pocklington Canal offering the best chances of sightings. Three
late juvenile Cuckoos were recorded on the 16th, 20th
and 25th whilst a male Redstart was trapped and ringed in the
poolside willows at Wheldrake Ings on the 19th, when the first of
the autumns Whinchats were present at North Duffield Carrs. Three Crossbills
south at Wheldrake Ings on the 18th were also notable.
Brown
Hares appear to have enjoyed a successful season with
large numbers present throughout the valleys meadows including good numbers of
young. Adders and Grass Snakes continued to show well on Skipwith
during the month whilst butterfly numbers increased, with it proving to be a
bumper year for Ringlets and particularly Meadow Browns. The
first Gatekeepers appeared on the wing in the middle of the month as
expected, particularly where bramble had come into flower. Five Marbled
Whites were recorded around the valley, which mirrors the increased trend
of recent years – and represented a new species recorded for the first time on
Skipwith Common NNR. A Dark Green Fritillary at the NNR base garden was
also a first for the reserve. Moth numbers and diversity also increased during
the month with five species of hawk-moth caught at the reserve base on the 12th,
including two Pine Hawk-moths and a Small Elephant Hawk-moth. A Hummingbird
Hawk-moth on the lavender at Bank Island on the 20th was the
third in as many years.

them directly to us.

25 ducklings (four broods), remained at Wheldrake Ings during the month.
Tufted Duck – Three pairs with a total of 11
young were present at Wheldrake Ings throughout the month.
Grey Heron – Birds
were scattered throughout the site with 14 at Wheldrake Ings on the 30th

Grey Herons - Wheldrake Ings - 02/07
Little
Egret – Up to four adults were present throughout the
month and were seen making feeding flights into the local heronry. Birds were
regularly seen fishing on the Wheldrake pool and at Bank Island, with scattered
sightings from elsewhere, including several records coming from the Pocklington
Canal in the Hagg Bridge and Melbourne area. Nine birds were present between
Wheldrake Ings and Bank Island on the 24th – thought to be
two local broods of three and two.
Little Grebe – A
single on Wheldrake Ings on the 4th was likely to be a
dispersing post breeding bird.
Red Kite – A
single was present at North Duffield Carrs on the 1st
and 2nd with two following hay cutting operations at North
Duffield Ings on the 4th. A single was over Bank Island on
the 14th, with two following the hay cutting machinery there
on the 15th when one was also reported from Melbourne. One was
at Wheldrake Ings on the 19th with three following tractors
at Bank Island/Wheldrake Ings on the 22nd and up to two there

Red Kite - Bank Island - 15/07
Marsh
Harrier – A
single pair remained in the valley between Wheldrake and Ellerton Ings where

Ings on the 2nd, and two
over North Duffield Ings on the 4th.
A single was at Bank Island on the 8th
and Thornton Ellers on the 9th, whilst three birds carrying food in
differing locations on the 12th
were presumably linked to the three breeding pairs in the area. A single was at
Bank Island on the 14th followed
by one near Pocklington on the 15th
heading back towards Canal Head and Bielby. A single flew over Wheldrake Ings and
Thorganby village on the 18th

Corncrake – A single singing male was
discovered on the morning of the 7th

ringed in the afternoon and was found to be a first year male which showed
