Once
again the only double figure counts for this species came from
the Otley area at both Otley Gravel Pits and Knotford Nook. Both
sites had their maximum figures during November with 28 at Knotford
and 26 at the Gravel Pits. Tong Park Reservoir had nine throughout
the last two months.
Breeding activity
was noted at Stockbridge Nature Reserve by 15th March and by
22nd May four cygnets hatched. By early June two were missing
but the other two survived. At Otley Gravel Pits three pairs
bred producing 13 young. The pair at a private lake only managed
to fledge one youngster. The Leeds/Liverpool canal hosted two
nests between Bingley and Silsden, one with five young the other
with seven. A pair attempted to breed at Raw Nook but failed. |
2004 |
In
complete contrast to last year’s high count, this year’s
was in the spring, with 26 being seen at Otley Wetland in April.
Double-figure counts occurred at this site several times throughout
the year, with Yeadon Tarn being the only other site to have
more than 10, when 11 were seen at the end of the year.
Breeding took
place at six locations, with 32 young being fledged. During August,
two were seen with red neck-rings, which indicated they had been
ringed at Ripon and Hay-a-Park Gravel Pits, both in 2001. |
2005 |
The
number of records, numbers of birds, and the maximum count (28
birds at Otley Wetland on 6th May) are all in line with other
recent years. Colour-ringed birds were seen at three locations,
indicating some movement both within and from outside the recording
area.
Evidence
of breeding was first noted on 10th April, and took place at
six locations at least. Three pairs bred at Otley Wetland, a
pair at a private site, two pairs at Knotford Nook, and, on the
canal, two pairs at Silsden and a pair at Micklethwaite and Crossflatts.
Specific data on breeding success was not entirely forthcoming,
but 13 young were ringed at Knotford Nook and Otley, 10 juveniles
were seen at Silsden, four at Micklethwaite, and the same number
at Crossflatts.
A
particularly spectacular, if gory, incident was witnessed at
Stockbridge Nature Reserve, when two swans were described as
literally fighting to the death, with the weaker of the two surviving
only by obtaining refuge under a willow close to the hide (SR). |
2006 |
The
majority of the records, and all the double-figure counts, came
from the Otley area, where there is clearly a stable, if locally
mobile, population.
Numbers
were almost exactly in line with other recent years, and the
year’s
highest count was 29 birds at Knotford Nook on 30th October,
though correlation with other records from the same general area
at the time suggests they were referable to birds seen at Otley
Wetland on many occasions, and which had a maximum of 22 in the
latter months of the year. Other records, mainly of twos and
threes, came from various locations in Airedale, but with seven
birds at Yeadon Tarn in March, and a scarce Worth Valley record
of a bird at Leeshaw Reservoir in February.
As might be
expected, most of the breeding information also emanated from
around Otley, and it was considered probable three pairs had
attempted to breed at the Wetland Nature Reserve, where at least
11 young were seen, and five cygnets were also reported from
Knotford Nook. Elsewhere, four young were raised at Stockbridge,
three at Farnhill, seven at Cononley, and four young birds were
seen at a private lake. |
2007 |
The
pattern of records suggests this species’ status
is almost identical to other recent years.
Otley is clearly the local stronghold, and up to 24 birds were
seen on many occasions throughout the year. Apart from this, Wharfedale
produced few other reports, but there was a good scattering of
records in Airedale, mainly of ones and twos. Less often-reported
locations within the recording area included Addingham, Caldene
Fields, Riddlesden, and Larkfield Tarn, where five birds were seen
in February.
Breeding success at Otley Wetland was down on 2006, possibly due
to disturbance, and only five young were raised. Elsewhere, small
cygnets were seen at Stockbridge Nature Reserve, Shipley and Crossflatts
(where there were two), but the best result came from a private
site, from where a pair and seven young were reported. |
2008 |
Numbers clearly remain fairly static, especially
around Otley, where 27 birds at Otley Wetland in September and
November is about the norm for the area, and successful breeding
took place here. |
2009 |
The records received indicate a fairly stable picture,
and maximum counts, for example 25 at Otley Wetland in January, are
in line with other recent years. There was successful breeding on
the Leeds and Liverpool Canal, and at Stockbridge, Farnley and Otley:
about 38 young were seen. |
2010 |
The
local population has been largely unchanged for several years,
confirmed by the year’s maximum
count from the Otley area of 33 adult birds in August, including
29 at Otley Wetland. At least nine nests were located, at Stockbridge
Nature Reserve, Farnley, Crossflatts, Knotford Nook and Otley Wetland,
with up to 23 young being raised. |
