Once again the pattern of sightings
favoured the latter half of the year. The New Year saw numbers
notably reduced with no double figure counts and, even, a total
lack of sightings in February. The 6 seen on a private lake on
11th April were the high count for the first winter period. Whereas
the build up at Knotford Nook in November reached a group record
of 135! During this period Lindley Wood Reservoir also had a good
total of 80 present but it is believed that these would have been
birds from Knotford.
Other sites having mainly single figure counts included; Silsden
floods, Cold Edge Dams, Chelker Reservoir, Fewston Reservoir, Ogden
Water, Stockbridge, Thornton Moor Reservoir, Silsden Reservoir
and Redcar Tarn. |
2004 |
Whilst
the first returning birds were two at Thornton Moor Reservoir
on 5th August, the Otley area dominated the records, with over
half the 140 reported sightings coming from Otley Wetland or
Knotford Nook. All counts over 50 came from the latter site,
and after 28th October. The peak count of 84 on 2nd December
was considerably down on last year’s 135 at the same site.
Elsewhere, Cold Edge Dams had 39 fly past on 5th September, and,
on 1st October, 23 were seen at Thornton Moor Reservoir during
another visible-migration count. Eighteen were seen on 3rd October
on Lindley Wood Reservoir, which had its highest count of 48 on
23rd. These might also have been the birds seen at a private site
mid-month. |
2005 |
Whilst 40 fewer records were submitted than in
2004, numbers of birds were generally higher, and, in particular,
there were more sightings in the early part of the year.
As
usual, most of these came from the area round Otley and the Washburn
Valley, and Knotford Nook dominated proceedings in January, producing
six double-figure counts and a maximum of 80 birds on 15th. Numbers
in the following seven months were much reduced, with only one
party of more than twenty birds, this being 26 at Otley Wetland
on 18th March. Visible-migration from September turned up small
numbers of birds at a number of locations, including Cold Edge
Dams and Thornton Moor Reservoir, where 25 were seen in October,
but that month’s highest
count was 40 birds at a private location.
This
site again had the same number of birds on two dates in December,
and thirty were at Thornton Moor on 15th November. The latter
month provided the year’s highest count of 123 at Lindley
Wood Reservoir on 5th, having increased to this total from 110
two days earlier. |
2006 |
A good year, with 90 records covering 19 locations,
and including 44 double-figure counts.
Most records for the first winter period came from the Otley area,
where there were several counts of between 20 and 26 birds, from
Knotford Nook, Otley Wetland and a private location, and the highest
aggregate for the early part of the year: 52 birds at Lindley Wood
Reservoir on 16th February. Elsewhere, 22 birds were seen at Cononley
Ings in March.
Sightings
petered out by mid-April, but there was a notable summer record
of a bird at Otley Wetland on 8th June. Presumed migrants brought
the first records of autumn, and these came almost entirely from
the south of the area, with double-figure counts in September
at the reservoirs at Lower Laithe, Warley Moor and Thornton Moor
(which produced the period’s highest number of 22), and Denholme
Clough. The main numbers were seen from the end of October, with
50 birds in October and December at Knotford Nook, and up to 54
at the private lake. However, Cononley Ings, included in the Group’s
recording area for the first time, produced several counts of up
to 38 birds in this period, and a record total of 150 on 3rd December
(MSm).
Birds were also seen this year at several sites where they are
relatively unusual, namely Tong Park Reservoir, on the Wharfe at
Strid Wood, and St. Ives, although the bird seen there was considered
an escape. |
2007 |
Whilst there were more records than in 2006, numbers
were generally lower, and birds were seen at slightly fewer locations.
Apart from two records from Strid Wood and Cononley Ings, all
the reports in the first winter period to the end of March came
from the Otley area, where there were maxima of 30 birds at a private
site and 38 at Lindley Wood Reservoir, both in March, and 37 at
Knotford Nook in February. These may have been the same mobile
birds, as could smaller numbers seen at Otley Wetland.
Apart from three records from the same area in April, nothing
else was seen until 6th September, when there was a bird at Stockbridge.
Unlike the early months, the final third of the year had small
numbers of birds, clearly on passage, at 11 locations away from
Wharfedale, but the only significant numbers continued to come
from there, comprising between 16 and 36 at Otley Wetland, and
up to 22 at Knotford. |
2008 |
In the first winter period, up to the end of March,
most records came from the Aire Valley and around Otley, and the
highest of many double-figure counts were 54 at Knotford Nook in
February, and 48 at Cononley Ings in January. Knotford also had the
biggest count in the second winter months, with 63 in December, and
60 were at Cononley in that month. |
2009 |
Almost all the records originate from the Washburn
Valley, the Otley area, and the seasonal floods around Cononley.
Most of the bigger counts were typically around the sixty mark, but
there were exceptionally high tallies of 86 at Knotford Nook in January
and up to 120 there in February, and 93 at Otley Wetland in October,
when Thornton Moor had an untypically high 61. Whilst Cononley Ings
had produced 66 birds in January, it was eclipsed in the second winter
period by a Group record count of 234 on 2nd December, though this
quickly diminished as the birds moved on. |
2010 |
Essentially a winter visitor, though
this year up to three birds were seen at Otley Wetland in May, and
two at Knotford Nook in early August. Totals were much in line with
other recent years. Otley Wetland had up to 41 in January and 45
in November, Knotford 56 in January and 31 in October, and the Aire
Valley floods produced up to 100 birds at Bradley Ings in November,
there having been 36 in that area in January. Six other locations
amassed a total of 87 birds. |
