Lower Derwent Valley NNR - July Sightings
It was largely 'as you were’ in terms of highlights,
with the pool at Wheldrake Ings attracting large numbers of Grey Herons and Little
Egrets, as well as yet another Great White Egret and Common Crane.
Three calling Corncrakes remained vocal during the first half of the
month including a regular calling bird on Bubwith Ings. Other breeding season
news concerned a single brood of five Pintail which reappeared during
the month, whilst a single newly fledged Black-necked Grebe at North
Duffield Carrs confirmed a successful outcome for that pair. Duck broods
(notably Gadwall and Shoveler), continued to appear throughout the month,
whilst Water Rails appeared to have had a bumper breeding season and showed well
- a minimum of ten young were seen (along with a few adults), from at least
five broods at Wheldrake. An eclipse drake Garganey showed well on the pool during
the second half of the month whilst a female Mandarin added a touch of the
exotic on the 28th. Three Sandwich Terns over Wheldrake
on the same date represented the second record of the year for the species.
Heron 'fest' - Wheldrake - 14/07 - DB
An Osprey passed over on the 4th
whilst two or three Marsh Harriers, four pairs of Red Kites, two juvenile
Peregrines and several Hobbies continued to be reported. Much attention
focused on the start of the autumn wader passage with Little Ringed Plover and
the first returning Golden Plover on the 12th, followed by two or
three Ruff and a trickle of Black-tailed Godwits (max 25 on the 26th), ten Green Sandpipers, four Common Sandpipers, two Wood Sandpipers (8th
and 28th onwards) and the first returning Greenshank. Large flocks
of Lapwing contained good numbers of juveniles with the last local birds
fledging around the 12th. Following a good breeding season for
Curlew, several unfledged broods were still present on the 12th with
a couple of small family parties remaining on the 26th.
Curlew - North Duffield - 12/07
Both pairs
of breeding Common Terns raised three young during the month and
attracted other passing adults and fledged young. Cuckoos were still
present early on in higher than usual numbers, whilst Kingfishers showed well
throughout the site, and particularly well around the pool which
attracted several fledged young. A single Grasshopper Warbler reeled
there from the 12th – 15th, whilst a recently fledged Cetti’s
Warbler represents the first confirmed breeding for the valley following
calling birds nearby earlier in the summer. Four juvenile Willow Tits
were ringed in the Wheldrake poolside willows whilst several Corn Bunting were heard
singing across the Ings meadows.
The hot weather conditions resulted in a surge of
butterfly records with large numbers recorded, including Comma
and Brimstone, and the first Essex Skipper for the area was notable record - coming from the old Escrick Mine site in Wheldrake Parish, the
same site also hosted a small colony of Marbled Whites. A single Brown
Argus was recorded from the base garden at Bank Island with yet another Dark
Green Fritillary (now almost annual in the valley) at Wheldrake Ings, and
likewise, a Humming-bird Hawk-moth in a Thorganby garden during much of
the month.
Brown Argus - NNR base - 31/07
Many thanks as always to everyone who has contributed
records throughout the month, inparticular to members of the YOC and regular
valley birder Duncan Bye for his records and photographs (credited DB).
BIRDS:
Whooper
Swan – Two remained at North Duffield Carrs early in the
month, with one unfortunately found dead there on the 12th.
Mute Swan – Up
to 12 pairs remained with broods throughout the month, with most other
non-breeding birds moving away to moulting sites elsewhere, the incredibly dry
conditions no doubt also helped see them on their way. Up to 12 non-breeders were
present and moulting on the river and various ditches.
Greylag
Goose – 100+ were present on a farm pond at East
Cottingwith on the 12th. Only small numbers present thereafter as
local breeders dispersed.
Canada
Goose – A single pair with four young were present on the
pool at Wheldrake.
Egyptian
Goose – A single pair remained at East Cottingwith with
another pair at Foggathorpe. Up to four non-breeding birds roamed the wider
area.
Wigeon – Up to five drakes and four
females remained in the valley, largely on the extensive ditch network.
Teal – Three were present at Wheldrake
early in the month. A single adult female was caught and ringed at

numbers increasing to 12 on the 18th.
Up to 10 were recorded until the 28th
with 13 on the 29th and
20 on the 31st.
Pintail – A pair with five well grown
ducklings were found at Wheldrake on the 10th,
following a period of not being able to locate the pair – the drake was later caught

occasionally thereafter, with a second, eclipse drake also present there on the
23rd.

were present at Bank Island. Up to 63 were counted throughout the site at this
time. 23 were present at Wheldrake on the 12th with 29 there on the 14th. Numbers on the pool declined thereafter as
water levels receded and fish stocks became depleted. 17 were roosting on Swantail
Ings, Wheldrake during the day on the 25th.
Little
Egret – Large and increasing numbers were present early in
the month as further local juveniles fledged from the heronry. 34 were present
on the pool at Wheldrake on the 4th with 50+ present
throughout the whole site on the 5th. 20 were still
present on the pool at Wheldrake on the 12th when six were at
North Duffield Carrs and five at Aughton Ings. 17 were at Wheldrake Ings on the

at Wheldrake on the 4th with
two there with two adults on the 7th

juveniles (from probably three separate broods) and two adults were present on
the 16th with six
juveniles (four broods) on the 17th.
From the 22nd onwards, a pair were also seen with three newly
hatched young, presumably a second brood. Five were seen on the 25th (including two fledged
immatures and a single juvenile). A further juvenile, from a different brood
was seen on the 30th. In
total – at least six broods were recorded on Wheldrake with a minimum of 11
young present, and although only three or four individual adults could be
accounted for, presumably others were present in the area.
Water Rail - Wheldrake - 16/07
Corncrake – A single calling male was
still present and vocal at Bubwith Ings until the 15th, with two there on the 12th and a single again on the 21st. A single was calling at Bank Island on the 13th.
