Lower Derwent Valley NNR - May Sightings
Once again coverage was limited due
to the lockdown, however it did slightly increase with the easing of
restrictions during the second half of the month. Thank you to everyone who shared their local
sightings during this time.
Lingering waterfowl included two or three Whooper
Swans, the last Pink-footed Goose (14th) and a late Goldeneye
(26th). It was another good month for returning Garganey with
up to nine pairs present, thus attracting a steady stream of admirers towards
the second half of the month. Grey Herons and Little Egrets
both had successful breeding seasons, with 34 and 19 active nests respectively.
A Great White Egret was present on the 13th/14th,
followed by a Common Crane on the 25th and three on the 28th.
It was a good month for raptors with an Osprey
at Crockey Hill on the 1st and a lingering bird in the Melbourne
area from the 20th. Hobbies also put on a good show with up
to 11 feeding over the pool at Wheldrake Ings early in the month, and scattered
birds elsewhere throughout the site. An adult male Red-footed Falcon was
also present with them on the 7th, with another possible first-summer
bird reported at North Duffield Carrs on the 16th (too distant for definite
confirmation). Passage wader movement on the other hand was poor, with just a
handful of Ringed Plover, Dunlin, two Greenshank and a single Ruff, Black-tailed Godwit and Common and Wood Sandpipers. 20 Whimbrel were still at the
Wheldrake roost on the 5th with the last individual recorded on the
24th, whilst two pairs of Little Ringed Plover were thought
to be breeding at Bank Island.
Other notable records and counts included an
encouraging 35-40 Cuckoos throughout the area, a Nightjar
churring at Skipwith Common on the 19th, a further three singing Grasshopper
Warblers, three singing Quail, and six Cetti’s Warblers
holding territory around the reserve.
BIRDS:
Whooper
Swan – Three remained at North Duffield Carrs between the 1st-6th
whilst a single flew north-west calling on the 4th. A single
lingered on the river at North Duffield from the 11th to
month end, with presumably a different bird at Wheldrake Ings on the 20th.
Mute Swan
– Numbers of non-breeders remained high with 58 at
North Duffield Carrs and 41 at Wheldrake Ings on the 5th. 88
non-breeders were still present throughout the site on the 11th,
followed by 79 on the 18th - down to 47 at month end.
Mute Swan and cygnets - Wheldrake - 27/05 - DB
Pink-footed
Goose – Two at Bank Island on the 6th with
one there on the 14th.
Egyptian
Goose – Two were still present at East Cottingwith on the
1st with three on the 11th and a single on
the 18th. Four flew into Bank
Island after dark on the 26th.
Shelduck – 76 birds were loafing
on the river bank at Thorganby Ings on the 1st with a
total of 87 birds present throughout the site on that day, many of which were
off-duty males. 43 were at North Duffield Carrs on the 6th. A
pair with seven ducklings were observed walking through a garden in Elvington
on the 23rd before heading down the Main Street.
Shelduck - North Duffield - 06/05
Teal – Up to 30 pairs were present
throughout the site during the month.
Garganey – A total of nine pairs were
located around the site on the 1st
with new pairs at Thornton Ellers and at Hagg Bridge. These males were still
present on the 4th and 5th, by which time the females
were thought to be incubating – appearing more typically at dawn and dusk. Single
drakes were still at Bank Island and Wheldrake on the same date (with presumed
females now also nesting), along with additional pairs at Wheldrake and North
Duffield. Up to two pairs remained regularly at Bank Island thereafter, with
two drakes chasing a female at Wheldrake on the 16th, when a single pair were also present at North Duffield
Carrs, Hagg Bridge and Thornton Ellers – total of six pairs and a single drake
on that date. Four drakes and at least two females remained at Wheldrake, with a
pair at Bank Island and two additional pairs elsewhere to month end - at least
five pairs, possibly as many as seven.
Garganey - Bank Island - 06/05
Mandarin – Two drakes were present at
Bank Island on the 17th and
again on the 20th.
Mandarin - Bank Island - 17/05 - DB
Wigeon – Up to 11 drakes and five females remained throughout, with five apparent pairs involved.
Goldeneye
– Two red-heads were still on the pool at Wheldrake
on the 1st. A single red-head was then present there on the 16th-26th.
Little
Egret – Up to 24 were located across the site during the
day on the 6th, whilst a visit to the heronry on the 7th
produced a count of 19 active nests, including some with small young.
Great White
Egret – A single was present in the Thornton area on the 13th
with one north over Bank Island on the 14th.
Grey Heron – 19 were present at Wheldrake Ings with 11 at
North Duffield Carrs on the 5th. A total of 26 were at
Wheldrake Ings on the 6th, which included the first six
fledged young from the adjacent heronry. A visit to the heronry on the 7th
produced a count of 34 active nests, many of which had large, almost ready to
fledge young. The settled weather, with a lack of strong winds, appeared to
help in an early and productive breeding season.
Osprey – A single was found at Pool Bridge Farm on the 1st (DB) with
another at Brickyard Farm Melbourne on the 20th (CSR). What
was presumably the same bird was present at Melbourne on the Pocklington Canal
on the 25th (DS), and later seen fishing over the pool at
Wheldrake on the 27th (DB).
Perhaps the same bird was also present at Oak Mere Farm fishing ponds near
Skipwith on the 28th (CSR).
Osprey - Pool Bridge Farm - 01/05 - DB
Marsh
Harrier – One or
two birds lingered throughout the month.
Peregrine – A single first year bird was
at Wheldrake on the 1st, with
further records in the core valley on 4th,
7th and 12th.
No further reports thereafter, however four or five pairs were present in the
wider area.
Hobby – Three or four continued to be
seen daily in the Wheldrake/Bank Island area early in the month with one at Thornton
Ellers on the 1st. Four were present over the pool at
Wheldrake on the 3rd with
one at Bubwith Bridge on the 4th.
Seven were over the pool at Wheldrake on the 5th with three at Bank Island on the same date. Nine
were over the pool at Wheldrake on the 6th
followed by 11 there on the 7th.
Singles were present over North Duffield Carrs and Thorganby on the 12th, with two hawking
emerging Mayflies over the River Derwent at North Duffield Carrs on the 14th with a single also at
Wheldrake Ings. Two were present over Thorganby Ings on the 17th when three were at North
Duffield Carrs, followed by two there on the 18th. Two were present at Wheldrake on the 20th with regular sightings
of ones and two throughout the site thereafter.
Hobby - Wheldrake Ings - 07/05
Red-footed Falcon – A single adult male was observed
over the pool for 20 minutes at Wheldrake on the 7th, amongst a feeding flock of 11 Hobbies, before
slowly drifting south with some of the Hobby flock (CSR, NCa). Presumably the
same bird was relocated in subsequent days from Humberhead Peatlands NNR. A
possible first-summer bird was seen distantly from North Duffield Carrs on the 16th, and although
considered by the observer to be almost certainly this species and age, it was too distant to confirm beyond all doubt (DW).
Red Kite – Regular throughout the month and
now more common than Marsh Harriers on the Ings during the summer. Five
were at Bubwith Ings on the 6th
when three were at Wheldrake and a single at Thorganby on the same date.
Probably four or five breeding/non breeding pairs in the area.
Coot – The first brood (four) were at
Wheldrake on the 11th.
Water Rail – A total of six pairs were at
Wheldrake, with two pairs at Bank Island and two pairs at Thornton Ellers. Single
pairs were also present at North Duffield Carrs and Aughton Ings.
Quail – A single singing male at North
Duffield Carrs at dusk on the 20th
with two at Thorganby on the 31st.
Common Crane – A single was present from Bank
Island on the 25th with
three over Skipwith Common on the 28th.
Great Crested Grebe – A single pair remained on the
pool at Wheldrake from the 1st–5th.
Little Ringed Plover – A pair were present at Bank
Island on the 3rd with
three there on the 4th
and again on the 5th-7th.
A single was present at the same site again on the 12th with a pair seen copulating the following day. Four
were present on the 14th
to month end and were thought to be attempting breeding, with one pair
incubating from the 24th.
A single pair also bred and hatched a brood of four between Wheldrake village and
Escrick on the 19th.
Little Ringed Plover - Bank Island - 22/05 - DB
Ringed Plover – A single at Bank Island was a
rather late first of the year on the 11th.
Seven then followed there on the 19th
with four on the 20th and
one on the 25th – all
presumably of the larger, brighter ‘tundra’ race.
Lapwing – The first juveniles to be
reported were a brood of two on the 5th - observed walking over the road at Bank Island, and
then down onto the Ings having hatched on nearby arable fields. A brood of three
followed at North Duffield Carrs on the 6th,
with two broods (of three and two) seen on arable at Menthorpe on the 7th.
Woodcock – Four ‘roding’ birds were
present at Skipwith Common on the 18th.
Black-tailed Godwit – A late single at Bank Island on
the 13th.
Dunlin – Two late passage birds were
present at Bank Island on the 17th–21st with one remaining on the 22nd. Three were present from the 23rd to the 26th followed by two on the 27th.
Whimbrel – Numbers at the Wheldrake roost
fell quickly following the peak with 20 at the roost on the 5th. Several individuals were observed visiting Wheldrake during the
day around this time, as is often the case with these later birds. Three were
present during the day on the 6th
with another at Bank Island, and seven at the roost in the evening. A
single at Bank Island on the 7th
was followed by three during the afternoon of the 12th at Wheldrake, with two birds heading north there at
dusk later the same day. Two were present again on the 13th with one at Breighton Meadows on the 24th.
Ruff – A single flew south over
the pool at Wheldrake Ings on the 20th.
Redshank – Up to 20 pairs were present
throughout the valley during the month. Birds
were largely confined to the wetter sites of Wheldrake and North Duffield,
whilst up to five birds frequented Bank Island during the second half of the
month.
Greenshank – Two were present at Thornton
Ellers on the 1st with one remaining on the 4th
and 5th. One at Bank Island was also present on the 5th
whilst a single flew north over North Duffield village after dark on
the same date. A single was present at Bank Island from the 29th to month end.
Wood Sandpiper – A single flew north over North
Duffield Carrs calling on the 6th.
Singles were also logged (calling after dark) over Thorganby village on
the 5th,
6th and 7th – possibly relating to
the same mobile individual.
Common Sandpiper – A single was present on the pool
at Wheldrake on the 14th with
one at Bank Island on the 20th.
Common Gull – 23 sub-adults and four adults
were at Wheldrake on the 1st,
with nine still present on the 5th
– part of the small spring passage movement recorded annually at this time.
Lesser
Black-backed Gull – A
single immature at Wheldrake on the 6th
with 130 on the riverbank at Thorganby from the 15th–19th, where up to 20-30 remained
throughout the month.
Black-headed Gull – A single pair attempted to
breed on the pool bund during the month, but had appeared to fail and moved on
by the end of the month.
Yellow-legged Gull – A first year bird was present
at Wheldrake on the 2nd.
Common Tern – Nine were still present across
the site on the 1st. Pairs
were then regularly seen at both Wheldrake Ings and North Duffield Carrs, with
a pair also present at Pool Bridge Farm at Crockey Hill on the 2nd – possibly birds
wandering from either the valley or the nearby University. Two pairs had
settled onto the rafts by the 11th
with the pair at Wheldrake incubating a clutch of three eggs by the 18th. It would appear this
attempt failed but the pair were looking like laying a repeat clutch by the end
of the month.
Cuckoo – Two calling males were present
at Thornton Ellers on the 5th,
with a single at Wheldrake on the same date. Four singing males were on
Skipwith Common on the 6th
with one in nearby Skipwith village later in the day and a single at Storwood. A
single flew across North Duffield Carrs on the 7th, hotly pursued by several Meadow Pipits. A calling
male was reported between Stamford Bridge and Low Catton on the 8th when two were also
present in the Beilby/White Carr Meadow area of the Pocklington Canal. A pair
were present in the reedbed at Wheldrake at dusk on the 11th with one at Bank Island on the 12th and two at Thorganby. Five calling birds were
on Skipwith on the 13th. Two
were present around White Carr Meadow, Beilby on the 14th with a further two along the canal at Canal Head. Two males and a hepatic female at Wheldrake on the 15th. Five (four calling males and another hepatic
female) were present in the Melbourne Ings area on the 15th. A pair (male and hepatic female) were present at
Thornton Ellers on the 18th
when single birds were also present at Thorganby and Seavy Carr.
A full
survey of the canal produced a total of 18 calling males along its length, with
an estimated 35-40 calling males throughout the whole site. Possibly at least
two or three hepatic females were also present.
Cuckoo - Wheldrake - 16/05 - DB
Nightjar – A single churring male was
present at Skipwith Common at dusk on the 19th
– presumably newly arrived as the site was visited and non were heard on the 18th.
Lesser Spotted Woodpecker – A single on the riverbank at
Wheldrake on the 6th.
Swift – 500+ moved through Wheldrake
Ings and 300+ went through North Duffield Carrs on the 1st. 100+ were present at Wheldrake on the 5th. Numbers reduced
thereafter with many local villages recording an arrival or build up in numbers,
suggesting local birds had dispersed away from the Ings and back to local
breeding sites.
Kingfisher – Up to eight pairs were recorded
throughout the site.
White Wagtail – A single on the new scrapes at
Bank Island on the 14th
showed well.
White Wagtail - Bank Island - 14/05

Skipwith Common on the 2nd
with one at North Duffield Carrs on the 11th.
Whinchat – A single between Escrick and
Wheldrake on the 18th.

excavating holes in the Bank Island bank on the 14th with regular activity thereafter - following a rather slow
start and build up.
Sand Martins - Bank Island - 14/05
House Martin – 300+ were present and moved
through Wheldrake Ings during the course of the day on the 1st.
Mistle Thrush – A pair with three fledged
young were present at Thorganby Thicket Priory on the 7th.
Mistle Thrush - Thicket Priory - 07/05

present at Wheldrake Ings on the 6th,
with a pair at Melbourne Arm on the 19th. Two pairs were also present at Skipwith village by
month end.

numbers.
Garden Warbler – Further arrivals continued with
increasing numbers between the 1st-3rd throughout
the site.
Whitethroat – A good year for the species
with the first fledged young appearing late in the month.
Grasshopper Warbler – A further bird was found
‘reeling’ at East Cottingwith by the Pocklington Canal on the 5th,
with another off Sands Lane at Skipwith Common on the 18th to month end. Single at Wheldrake on the 24th to 27th.
Cetti’s Warbler – At least four, possibly five
singing males were present throughout with a new (sixth) male caught and ringed
at Thornton Ellers on the 18th.
Linnet – 50 at Thornton Ellers on the 5th was the largest group, and
appeared to be breeding throughout the site in above average numbers.
Linnet - North Duffield - 12/05
OTHER NOTABLE RECORDS:
Three Fallow Deer were observed
in the woods opposite the car park lane at Wheldrake Ings on the 26th. Two Holly Blue butterflies
were seen at Breighton Meadows on 7th. A Chocolate Tip moth
was caught overnight at the NNR base on the 21st. A Hairy Dragonfly
was seen at Wheldrake Ings on the 20th. A Grass Snake was
unfortunately a victim of being run over and was found dead on the road on Bubwith
Bridge on the 4th.
A really useful point of reference this blog. Thanks for putting it together each month.
