Fairly
common passage migrant/scarce and sporadic breeder |
2003 |
Not
over-common in the area. The first for the year was one at Otley
Gravel Pits on 9th March followed by three over Kex Gill on 30th
with singles in April at Fewston Reservoir, Otley Gravel Pits
and on Haworth Moor.
In May three
were at Otley Gravel Pits on the 1st with one at Leeshaw Reservoir
on the 12th and seven there the following day. The only June
records came from Thornton Moor Reservoir on the 16th and Leeshaw
on the 21st.
One was again
at Leeshaw on 19th to 23rd July and five were at Thornton Moor
on 24th August. There were no September records but one was at
March Ghyll Reservoir on 12th October and up to two were at Thornton
Moor Reservoir in late October, one being seen as late as 4th
November. |
2004 |
Once again,
the first record of the year was at Otley Wetland when four were
seen on 13th March. Two weeks later, six were at Thornton Moor
and there were further sightings at these two locations during
April and May. The latter month produced several records. Up
to three birds were seen displaying over Thornton Moor, Warley
Moor Reservoir had one on 16th and two on 30th, and Leeshaw Reservoir
had four present on 23rd, reducing to two by 27th. Thornton Moor
Reservoir still held three at the height of summer on 20th June.
The
earliest returning migrant was one seen flying north over Thornton
Moor on 18th July, the first of several autumn sightings here.
The month’s maximum of six was seen on 27th July, and others
were observed until early August. After a gap of some weeks,
two were noted on 24th September, and numbers built up again
during October and November, with a peak count of 15 on 7th October,
and the year’s final record, two birds, on 21st November.
Elsewhere,
Cold Edge Dams produced three birds on 8th August, and the same
number on 9th October. |
2005 |
A good year for the species, with particularly
high numbers during a productive period for wader passage around
the end of August. All but one of the many records came from the
south of the Group area, and, of these, the majority originated
from Thornton Moor Reservoir, which is, without doubt, the top
location in the area for wader passage.
The
first of the Thornton Moor records was a bird on 26th March,
and between that date and 26th June, birds were recorded there
on nine dates, with significant counts of six on 30th April and
five on 2nd May. A single bird had returned by 26th July, and
five were present five days later. However, the best totals were
reserved for the end of August and beginning of September, as
five birds were seen on 25th August, and fourteen flew past on
31st, with eight on the shoreline the following day. The year’s
final record was of two birds on 11th September, following three
in the preceding week.
Away from this location, up to two birds were seen at Cold Edge
Dams on six dates between 3rd April and 6th August, two were at
Otley Wetland on 6th May, one at Warley Moor Reservoir on 25th
June, and, notably, two at Soil Hill on 14th May, a site where
it is unlikely they have been seen previously.
Though there was no definite evidence of breeding, display calling
was heard from some of the birds at Thornton Moor during the summer
months, and a pair was present as Warley Moor Reservoir during
this period. |
2006 |
Of
the 42 records submitted, 65% of them related to Thornton Moor
Reservoir, and nearly all the rest also came from the south of
the area. Compared with 2005, there was a surprising lack of
autumn sightings after the first week in August, when most of
last year’s
big counts were made, and numbers at Thornton Moor were generally
well down, despite favourable shoreline conditions.
The first of the Thornton Moor reports concerned two birds on
27th April, following which birds were seen on 11 further dates
to the middle of June, with the highest count a fairly unremarkable
four on 9th June. What was probably autumn passage began at this
site with a single on 7th July, followed by reports of ones and
twos on a further nine days, and similar records on four days in
August and one in October. Comfortably the highest count in this
period was six birds on 1st August.
Other
locations had the year’s first and last sightings,
with single birds at Farnhill Ings on 16th March, and Redcar Tarn
on 25th November. Between these dates Otley Wetland had birds on
three days in May, including two displaying on the 7th, and one
day in June, and the same period produced two sightings at Leeshaw
Reservoir. There was a bird at Warley Moor Reservoir in early July,
and three there mid-month, and a good record of one flying over
Allerton on 24th September. Some five weeks later 14 birds at Chelker
Reservoir represented the highest number seen here, and two birds
present at Cononley Ings on the last day of October were probably
the same ones seen there on 2nd November.
Although display was noted at Otley Wetland, Warley Moor and Thornton
Moor, breeding was not established, but one observer considered
the birds frequenting Leeshaw Reservoir might have bred on adjacent
moorland. |
2007 |
Generally unfavourable shoreline conditions during
the passage periods made 2007 a poor year for many waders, and
the 30 Dunlin records were well down on many other years. Nearly
all the reports were for the three months from April, and, with
only six records, autumn passage was almost non-existent.
The first of the year was a bird at Thornton Moor on 14th April,
and the last was seen there on 17th November. The intervening records
from here were unexceptional (mainly ones and twos), apart from
a good count of nine birds on 19th May.
Only four other locations had birds: Otley Wetland, Silsden Ings,
Leeshaw Reservoir and Warley Moor Reservoir. Here again, single
birds were the norm, though up to three were at Warley Moor and
four at Leeshaw in May, and two at Silsden in July. |
2008 |
Another poor year, with only 17 records. The maximum
count of four birds came from Cononley Ings in January and Leeshaw
and Thornton Moor Reservoirs in July, and records were otherwise
mainly of ones and twos. These covered 14 dates between January and
August, but mainly in spring and late summer, and came from Bradup,
Silsden Ings, Thornton Moor, Kex Gill Quarry , Warley Moor and Snaygill. |
2009 |
The number of records is in line with last year, at
a fairly modest 16, but considerably more birds were seen, due mainly
to significant movements of 18 and 19 at Thornton Moor in May, and
15 in September, producing a total spring passage of about 60 birds,
and 23 in autumn. Only Kex Gill Quarry provided other records, having
three birds in May. |
2010 |
The number of records was, at 40,
considerably more than last year, and produced around 98 birds, which
was 15 more than in 2009. Almost all the reports came from Thornton
Moor Reservoir, with Leeshaw and Scargill Reservoirs, Redcar Tarn,
Bradley Ings and Otley Wetland providing only a handful. Breeding
activity was reported on moorland in the south of the area. |
