| Great
Crested Grebe by Malcolm Stones |
Common
resident breeder and passage visitor |
2003 |
It
was a poor year for breeding records with only three sites being
reported. Several other sites had birds displaying adults but
no records of young. Breeding occurred at Chelker, Ogden and
Lindley Wood reservoirs. Only one young was recorded at Chelker
and Lindley Wood with just adults on a nest at Ogden.
An
adult was seen on Swinsty Reservoir with a fully-grown juvenile
late in August, and at Knotford Nook, one had three juveniles
in accompaniment during the same month. The year’s highest
counts came from the Otley area with 8 being seen on two occasions,
at Otley Gravel Pits on 23rd February and at Knotford Nook on
24th October. |
2004 |
Once again,
only three locations had successful breeding from the 15 sites
from which reports were received. These were Otley Wetland Nature
Reserve, Knotford Nook and Lindley Wood Reservoir. None of the
breeding records involved more than one immature.
Yeadon Tarn
had the highest post-breeding counts, with a maximum of 12 in
November. One notable encounter was of an adult at Otley Wetland
tackling a well-grown Pike and winning! |
2005 |
This species
is usually well-recorded, and this year records came from ten
widespread locations, but mainly from the Otley area and Washburn
Valley. Up to seven birds were regularly reported, but the only
double-figure count (excluding family groups) came from Yeadon
Tarn, where wintering birds peaked at ten on 10th February.
There was evidence
of attempted or successful breeding at Lindley Wood Reservoir,
Hewenden Reservoir (two young), Otley Wetland Nature Reserve
and Swinsty Reservoir. Four juvenile birds were seen at both
of the last two sites. The number of breeding attempts is much
in line with recent years, but with rather more young birds fledged. |
2006 |
Records came
from 15 relatively widespread locations, in line with several
other recent years, though the waters around Otley and the Washburn
Valley continue to produce the most sightings. However, it was
good to see reports from at least three sites where birds are
generally scarce, Harold Park Lake (Wibsey), Warley Moor Reservoir,
and St. Ives, where two long-standing observers there had their
first records. After two years with double-figure congregations
in winter, there were none this year, though up to six birds
were noted regularly throughout, and there were locally good
counts of seven birds at Knotford Nook in September, and eight
at Yeadon Tarn and Lindley Wood Reservoir in November.
Breeding,
or attempts, at five locations has become the average in recent
years. This year, birds were successful at Otley Wetland Nature
Reserve, where three young hatched but probably only two survived,
at Knotford Nook (three juveniles), and, most notably, at Chelker
Reservoir, where a rare breeding record produced two young. A
bird was seen on a nest at John o’ Gaunt’s Reservoir,
and nest-building noted at Lindley Wood, but the outcomes were
probably unsuccessful. |
2007 |
A
well-recorded species, though only 15 sites were involved, in
line with last year, and most records came from lower Wharfedale
and the Washburn Valley. Notable exceptions were Cononley Ings,
Leeshaw Reservoir, where birds haven’t been seen for
many years, the Bull Coppy Wood area (near Saltaire) and Chellow
Dean.
Successful breeding took place at the last two, and at Otley Wetland,
with a total of five pairs producing nine young. Display activity
and nests were seen elsewhere, but without apparent breeding success.
Outside the breeding season the largest congregations were seven
birds at Yeadon Tarn and Otley Wetland in January, and at the second
site in March. |
2008 |
Still evidently common, with up to seven birds
being seen at a number of locations, including several pairs. Breeding
was proved at Otley Wetland and Silsden Reservoir. |
2009 |
Though
still common, the numbers of wintering birds were down, and five
at Yeadon Tarn was the highest. Breeding was attempted at Silsden,
Lindley Wood and John o’ Gaunt’s
reservoirs, and Otley Wetland, but only one juvenile was seen. |
2010 |
As with the preceding species, records came mainly
from Lower Wharfedale and the Washburn, though there were a few from
Bradford, Aireborough and the Worth Valley. There were no reports
from Yeadon Tarn, which has produced good counts of wintering birds
in previous years, and six birds at Otley Wetland in April was the
highest. Attempted breeding here and Knotford Nook produced four
young, but failed at Lindley Wood Reservoir. |
