Migrant
breeder/passage visitor |
2003 |
The
first returning migrants were at Marley on 18th April and at
Stockbridge four days later. Breeding was noted at Otley Gravel
Pits (at least two pairs), Silsden Reservoir and Stockbridge.
Birds were seen regularly at these sites as well as Chelker and
Fewston Reservoirs and Elland Gravel Pits until the last sightings
at Stockbridge and Otley Gravel Pits on 17th August. A single
bird at Denholme Clough on 10th August is likely to have been
a bird on passage as was one at Cold Edge Dams on 3rd September. |
2004 |
Otley
Wetland held the year’s first two birds
on the 21st April. This site then held various singing birds and
a few breeding pairs, with 10 birds ringed between May and July.
Stockbridge was also a regular site for up to two birds,whilst
the number of males peaked at Marley on 24th May with 22 present.
Breeding was suspected at Wydra, where up to two singing males
were present all summer, with the same scenario at Fewston Reservoir.
Elsewhere, low numbers came from sites such as Paul Clough, Chelker
Reservoir and Doe Park Reservoir. The last of the year was at Stockbridge
on 29th August. |
2005 |
Numbers
appear to be down on last year, particularly at Marley Sewage
Works, where this year’s highest count of
twelve birds, on 21st May, compares with the 2004 tally of 22.
The maximum count at Otley Wetland was six, up to three were at
Stockbridge, two were seen at Fewston, and singles at Doe Park
Reservoir, Chelker Reservoir, Elland Gravel Pits and Low Moor.
This last record was yet another from the productive garden mentioned
elsewhere in the Report. The first and last birds, at Marley on
26th April and Stockbridge on 4th September, were on unremarkable
dates.
Records
of confirmed breeding came from Stockbridge, where nestlings
and juveniles were seen, Otley Wetland, where parents were feeding
young, and Marley Sewage Works, at which location an adult pair
accompanied two juveniles. This last seems a particularly poor
return for what was formerly the area’s stronghold, and
at which double-figure counts were made earlier in the season.
Whilst there was no evidence of breeding at Fewston, the birds
seen and heard there were in exactly the same spot as in the
previous year. |
2006 |
The
first arrival was seen at Marley Sewage Works on 28th April,
a typical date and location, which figured again on 16th May,
when there were at least ten singing males there. By this time,
birds had also returned to Otley Wetland, and successful breeding
was subsequently established there, with six young being ringed.
It also took place at Stockbridge, where food-carrying was noted
as late as August, and at Pool Paper Mills (a new location, following
changes to the recording area), which recorded juveniles in May.
For the third successive year, breeding was strongly suspected,
but not proved, at Fewston Reservoir, whilst the access restrictions
imposed at Marley meant the site couldn’t be revisited to
check on breeding activity. In summary, the species is probably
maintaining its presence in the area, but without the anticipated
expansion in breeding.
Reports also came from irregular sites, at Weecher and Silsden
Reservoir, and it will be interesting to see if there are developments
at either in future years. There were no records of passage birds,
and birds on territory at Stockbridge on 16th August represented
the final, and untypically early, report. |
2007 |
A rather mixed year for the species, with numbers
certainly down on 2006, and breeding rather patchily recorded.
The
first and last birds, at Stockbridge Reserve on 22nd April, and
Otley Wetland on 4th September, were seen on unexceptional dates.
Most of the year’s
records came from these locations, with other expected contributions
from Marley, Fewston Reservoir and Chelker Reservoir, and less
expected ones from Knotford Nook on 2nd May, Silsden Reservoir
on the 24th, and Soil Hill on 27th August, where the birds (two
in each case) were almost certainly on the move.
Chelker Reservoir had the highest adult count of five males in
June, and successful breeding was reported from there, but elsewhere
only from Fewston and Stockbridge. Up to three singing males were
reported from Otley Wetland, but, surprisingly, there were no reports
of successful breeding. |
2008 |
Though
there were no specific reports of breeding, singing males and/or
pairs were reported from Stockbridge, Snaygill, Ben Rhydding, Yeadon
Tarn, Silsden Reservoir and Otley Wetland, which had the highest
count of five birds in May. |
2009 |
There
were singing males at seven sites: Stockbridge, Marley, Silsden,
and John o’ Gaunt’s reservoirs, Otley Wetland, Farnhill
and Snaygill, which had the biggest count of eight birds in May.
Whilst unreported, breeding probably occurred at the last location
at least. |
2010 |
There
was a surprising absence of breeding evidence for the third successive
year, despite singing males being reported from Otley Wetland,
Stockbridge, Leeshaw and Snaygill, where the 25 birds (clearly
migrants) recorded on 5th May was the highest total for 15 years. |
