Lower Derwent Valley NNR - July Sightings
Early returning waders dominated during the first
week of the month, with last year’s rotavating of Bank Island paying dividends
– the 2nd saw a Temminck’s Stint sharing the mud there with a
Wood Sandpiper, Common Sandpiper, four Green
Sandpiper, five Little Ringed Plover and the usual Lapwing, Curlew and Snipe.
Passage continued at a steady pace with two Avocets (21st),
the first returning Golden Plover (19th) and an influx of Wood Sandpipers
towards the end of the month (part of an arrival throughout the UK), bringing a
record-breaking flock of nine to the pool at Wheldrake. Lapwing still had
unfledged broods at Wheldrake to the 25th with a late brood of Redshank
also present to mid-month. A Woodcock on the riverside path at Wheldrake on the
25th was more unexpected and likely to have been a local breeder
dispersing from nearby sites.
It was unsurprisingly quieter for wildfowl , however Garganey
continued their excellent run, both in terms of breeding success and numbers -
up to two females and five males showed on the pool at Wheldrake throughout
much of the month, with Teal starting to increase reaching 17 by the 20th.
Two summering drake Wigeon
remained with up to two regular female Pochard. Up to
23 Little Egrets were counted early in the month with numbers decreasing
thereafter as birds dispersed away from their breeding colony (as far as
Blacktoft Sands and Saltholme RSPB reserves). Regular Marsh Harriers
were recorded but out-numbered by Red Kites for the first time; up to
seven adults and five young were noted following hay making activities around
the valley. Hobbies were also fairly regular throughout, with one or two
Peregrines continuing the increase in records.
Common Terns
fledged two broods (five young) from our rafts at Wheldrake and North Duffield,
and attracted more passage birds into the site than in recent years. The last
adult Cuckoo was reported on the 3rd, although a single
juvenile raised by a pair of Reed Warblers lingered at
Wheldrake between the 8th-19th, whilst another fledged
from a Wren’s nest at Skipwith
Common on the 29th. Kingfishers were active and showed well
on the pool at Wheldrake, with a second individual caught and ringed at the NNR
base on the 26th. A pair of Spotted Flycatchers raised three
young from a nest cup at Melbourne Arm, whilst seven juvenile Willow Tits
were caught and ringed between Wheldrake and Bank Island. A reeling Grasshopper
Warbler was heard at Wheldrake on the 13th.
Many thanks as always to everyone who has
contributed records and photographs throughout the month, in particular to members
of the YOC and regular LDV birder Duncan Bye (credited DB).
