Common migrant
breeder and passage/winter visitor. |
2003 |
Widespread
again this year and causing no concern as to status. The first
migrants were right on cue in the second half of March followed
by records from many sites. The usual mid-summer lull in sightings
was predictably followed by return passage birds turning up almost
anywhere where trees and bushes are present including Kex Gill
Quarry. Sightings were fewer throughout September and there were
only three October sightings with birds seen at Esholt, Denholme
Clough and Lindley Wood.
The last report
of the year came from Otley Gravel Pits on 4th December. |
2004 |
The only
winter record was of a single at Dowley Gap Sewage Works from
January until early March. The first singing bird was noted at
Sun Lane on 17th March. Ten days later there were nine singing
birds between Lindley Wood Reservoir and Swinsty Reservoir, and,
by 12th April, 12 were singing between Lindley Wood and Dob Park
Bridge.
Reported throughout
the area during the summer, with breeding proven at Strid Woods,
Lindley Wood Reservoir and Menston. Passage continued at many
sites into October, with the last at Barden on 24th. |

2006 |
The bird noted at Marley Sewage Works at the end of 2005 was
seen again on 3rd January, and what was presumably the same one
intermittently to 20th March. Another overwintering bird was seen
at Otley Wetland on 22nd January and 5th March. There was only
one report in the second winter period: a bird discovered near
Dowley Gap on 19th December.
Surprisingly,
there were no definite returnees in March, although the picture
may be confused by birds overwintering, and the first influx
didn’t occur until 1st April, when birds were seen
at Shipley Glen and elsewhere, followed by many reports throughout
the month at widespread locations. Singles predominated, but six
were seen and heard on several occasions in the lower Washburn
Valley, with seven being reported from there in May, and eight
in June. This, together with the same number at St. Ives in August,
was the year’s highest count, though one observer reported
good numbers present throughout the Denton Estate.
As normal, visible migration records were confined almost entirely
to the south of the area, and passage appeared relatively light,
with the 27 birds reported well down on last year. The last departing
bird was seen on 2nd October at Knotford Nook, somewhat earlier
than normal.
The
number of singing males clearly on territory wasn’t
reflected in a corresponding number of breeding records, though,
happily, there were a few more than in 2005. Reports of breeding
activity, including the presence of juveniles in some cases, came
from Strid Wood, Heber’s Ghyll Wood, Shipley Glen, Goit Stock,
Lindley Wood and Knotford Nook. |
2007 |
In a year when there were well over 200 records,
good numbers of birds (particularly on migration), and many reports
of birds on territory, it is a pity breeding scarcely got a mention.
There were only three reports: food carrying at Pool Paper Mills,
a pair with young at Goit Stock, and a presumed locally raised
juvenile seen at Damems in June.
A bird wintering at Dowley Gap was presumably the one seen there
in the previous December, but played to a much larger audience
between 3rd and 24th January. Two birds were present there a month
later, and a single on 10th March. Elsewhere in Airedale, birds
seen in early March at Low Wood, Goit Stock and Bingley could also
have wintered, but the last two (seen on the 11th and 13th) are
more probably the first spring arrivals. Two birds were also found
in the second winter period, at Stockbridge on 1st December, and
Weecher Reservoir on the 9th. Only three gardens figured in the
records: two in Bingley and one in Ben Rhydding.
There
was no great influx of birds until April, when up to seven were
seen at St. Ives on many occasions, there was a particularly
good count of eight there on the 14th, and there were twelve
in the lower part of the Washburn Valley four days later, having
increased from ten earlier in the month. However, the biggest
counts came in an excellent autumn migration period, when, between
late August and mid-October, an estimated 100 birds were seen,
principally in Denholme Clough, which had about 66, and Paul
Clough, where the total was fourteen. Denholme Clough also had
the year’s
highest daily count of 20 birds, present in the bushes with other
passerines on 28th August. The year’s final birds were seen
there and at Stockbridge on 14th October. |
2008 |
Status unchanged. Highest numbers were recorded around
Norwood Bottom, where there were up to 16 in April. Singles at Ogden
in November and Dowley Gap in December were clearly wintering, whilst
two in a Low Moor garden in mid October were probably migrants. |
| 2009 |
Remains common and well-recorded, with many reports
from the Washburn Valley, where 10 birds were noted at two different
locations in April. A wintering bird was seen at both ends of the
year in the Dowley Gap and adjacent Hirst Wood areas. |
| 2010 |
Well-recorded this year, particularly from Lower Wharfedale
and the Washburn, where at least 20 new arrivals were singing in
a short section above Lindley Wood Reservoir in mid-April. The many
other reported singing males translated into just one definite breeding
record, though nest-building and juveniles were seen. The only presumed
wintering bird was in Keighley in November. |
