Scarce
resident/possible breeder, common passage and winter visitor: mainly
coniferous woodlands |
2003 |
Unfortunately
there were no breeding records this year, although it almost certainly
took place in some of the larger coniferous forests such as Beecroft
Moor Plantation and Timble Ings. Many sites, for example Otley
Gravel Pits and St Ives, held flocks of up to 50 birds. Both Elland
Gravel Pits and Barden managed 70 birds each while 115 were noted
at West End in February. One observer had 120 birds at Lindley
Wood Reservoir in December and another had literally
“hundreds” at the same site during February. |
2004 |
In the first
winter period, numbers were higher than those of Lesser Redpoll,
with records of flocks of between 20 and 40 coming from sites
such as Farnley, Fewston Reservoir, Hag Farm at Burley, and Elland
Gravel Pits. The peak in March was of 50 in Timble Ings. A singing
bird was reported from the latter site during May.
Although there
were many records in the latter half of the year, the actual
numbers remained low. Forty frequented Lindley Wood Reservoir,
whilst only Fewston Reservoir could do better, with 60 during
October. Visible migration was comparatively light, with a total
of only 81 birds seen, principally at Thornton Moor.
Once again,
garden records were frequent, with Menston, Bingley and Baildon
all mentioned. |
2005 |
Generally a better year than 2004, with bigger numbers in the
first winter period, considerably better counts on visible-migration,
and a probable breeding record. Surprisingly, there were no garden
records.
In the first three months of the year, birds were recorded at
Timble Ings, Otley Wetland, the reservoirs at Thornton Moor, Fewston,
and Lindley Wood, plus St. Ives, the Barden area, and a private
woodland. St. Ives had a respectable total of thirty birds in February,
but the biggest numbers came from Barden, where between twenty
and 150 birds were seen between mid-January and the middle of February,
the highest daily total being seen on the 11th of that month. A
party of thirty birds seen near Denton on 3rd April were probably
dispersing.
The second winter period was comparatively quiet, and the only
notable counts were up to 40 birds at Otley Wetland in November
and December, 25 at Fewston, and twenty at the unusual location
of Saltaire. Smaller numbers were seen at Knotford Nook and Barden.
Autumn migration was first noted on 2nd September, and progressed
to 28th October. The figures for the established watch-points were
:
Paul Clough : 166 (maximum of 63 on 2nd October)
Denholme Clough : 241 (maximum of 71 on 2nd October)
Thornton Moor : 339 (maximum of 56 on 11th October)
It is pleasing to report that breeding almost certainly occurred
at Timble Ings, as a bird was seen carrying food there on 7th June,
and there was another summer record : a bird at Buck Park on 23rd
July. |
2006 |
The
reference in last year’s Report to there surprisingly
being no garden records seems to have done the trick, as this year
70% of the 56 reports in the first four months were from this source.
Previously mentioned gardens in Ben Rhydding and Otley predominated,
with 12 and 16 records, and there were others from Oxenhope, Gilstead,
Bingley, Baildon and Cononley. Otley regularly had six birds, and
seven were seen on 10th April. Not surprisingly, the bigger numbers
in this period came from elsewhere. Otley Wetland had two double-figure
counts, the best of which was 60 on 2nd January, the same number
was at Stockbridge on 12th February, and there was a locally good
count of 30 birds at Skipton Sewage Works on 22nd January. There
were also said to be many birds, though unspecified in number,
near Askwith.
In the second winter period, most of the larger counts came from
Stockbridge, where between 15 and 50 birds were seen to the year-end.
Otley Wetland had reports of up to 30 birds (though around 80 were
said to be present), and 24 were seen at Sunnydale, but the best
count came from Dowley Gap, where there were 70 on Boxing Day.
Whilst numbers seen on migration were lower than in 2005, a respectable
tally was still produced, with most records coming from the three
regular sites in the south:
Paul Clough 129 maximum of 79 on 26th September
Denholme Clough 164 maximum of 37 on 2nd October
Thornton Moor 106 maximum of 48 on 2nd October
About 20 birds were seen in total at a few other locations.
There was no indication of breeding, but a male was in song at
Timble Ings in April, a possible juvenile was seen in Ben Rhydding
in June, and there was an adult male at Thornton Moor Reservoir
in July. |
2007 |
The numbers seen this year were reasonably in line
with 2006, although, for some reason, garden records were well
down, after a remarkable upturn last year. Only two were featured:
the one in Ben Rhydding which seems to be a magnet to many species,
and where up to four birds were seen, and a Bingley garden which
had a single bird.
In general, wintering flocks provided the biggest counts, though
in the first winter period there were only three reports of more
than 20 birds, consisting of 60 at Stockbridge in January, and
between 70 and 200 birds at Barden Bridge in March, the latter
being the biggest single flock seen for 10 years. The final three
months produced more records, and there were parties of around
50 at Saltaire in October, and at Timble, Burley and Stockbridge
in November, whilst December had flocks of 30 at Riddlesden and
Barden, and 75 at Otley Wetland Nature Reserve.
The
autumn passage total of 456 was slightly up on 2006, and, as
usual, most birds were observed at the well-watched sites in
the south of the area, where Thornton Moor and Paul Clough had
similar totals of 139 and 149, though, in both cases, most of
the birds were seen on single days: 94 on 6th October, and 100
on 20th September. Denholme Clough’s aggregate was 96,
and a few other localities provided the balance.
For several years there has been reason to suspect birds might
be breeding at Timble Ings, though without direct proof of this.
The situation remains the same this year, with the discovery of
at least three fledged juveniles there in July. |
2008 |
Barden Scale contributed most of the records, with
between 60 and 100 birds on several dates in January, early spring
and August. Reports of around 70 birds also came from Toad Holes
Beck, Hollings Farm and Redshaw Gill. Autumn passage amassed about
330 birds, with 192 on the 23rd at Thornton Moor the highest count. |
2009 |
In
the first half of the year, 75% of the reports came from gardens,
indicating a marked change in recent recording patterns. The most
notable of these concerned an excellent count of 40 birds in a
Baildon garden, and a family party at one in Ben Rhydding, perhaps
indicating local breeding. The more expected locations’ totals
were well down on 2008, with maxima of 50 at Dowley Gap and Fewston.
Visible migration produced 212 birds, mainly over Thornton Moor. |
| 2010 |
Flock sizes were again generally
down on the expected norm of a few years ago, and, though there were
18 double-figure counts, a relatively modest 60 near Barden in February
was the highest. A few birds were seen in summer, but there was no
suggestion of local breeding. The autumn migration count of 270 (mainly
from Thornton Moor) was rather below the recent average |
