GREBE
Tachybaptus ruficollis
Fairly common resident breeder, winter and passage visitor.
Double figure counts have been hard to come by in recent years with only
a couple of sites coming close. Knotford Nook led the way with a maximum
of 16 seen in December 2003. The only other site to have double figures
was Chelker Reservoir but only after three pairs bred there, 12 were seen
in mid-September. Sightings came from 25 locations scattered across the
recording area throughout the year.
Another three breeding
records came from Low Dam (Thruscross), Dunkirk and a pair was seen at
their nest on Silsden Reservoir. The previous two sites had only one young
present.
GREAT
CRESTED GREBE
Podiceps cristatus
Common resident breeder and passage visitor.
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.
GREAT
CORMORANT
Phalacrocorax carbo
Locally common resident, passage and winter visitor.
The expansion wavered slightly again this year with the average roost
count at about 41 per month at Lindley Wood Reservoir, though this was
up on last years but still below 2001. Despite this the highest count
was increased again to 89, in October 11 more than last year.
The frequency of sightings
in the Aire Valley increased again in 2003. The only sightings of Sinensis
Cormorants were individuals at Otley Gravel Pits and Lindley Wood Reservoir
in the spring, when the adults show their breeding plumage. This was quite
poor in comparison with recent years.

LITTLE
EGRET
Egretta garzetta
Vagrant: previously recorded in 1997, 2001 and 2002
After the last two years it was fully expected that there would be more
records for 2003 than just the two received. Both sightings involved pairs
of birds, the first was at Elland Gravel Pits on 5th May which caused
quite a stir in the neighbouring area as they were the first record for
Halifax birders (BS). It wasn’t until 25th August when the next
pair was seen, flying down the Aire Valley, over Bingley (DJM). These
were only the fourth and fifth sightings in the groups recording area.
GREY
HERON
Ardea cinerea
Common resident and colonial breeder.
Quite a well recorded species throughout the recording area. Double figure
counts away from breeding colonies were as follows; 10 and 12 at Marley
sewage works on 18th May and 14th June respectively; at Lindley Wood Reservoir
there were 13 on 27th September, 12 on 25th October and 18 on 16th November;
the only double figure count in the first half of the year was of 17 at
Lindley Trout Farm on 14th January.
Breeding was recorded
at three locations. A massive total of 35 nests were found at Askwith,
over 100 young were present, there were another 10 nests at Dob Park.
At a private site 19 nests produced over 60 young. Back

WHITE
STORK
Circonia circonia
Possible scarce vagrant, and annual escapee.
All four sightings were in the months of April and May. The first observation
was of a pair over Knotford Nook on 20th April flying down the valley.
Five days later a singleton was spotted over Silsden. The next sighting
was another individual circling high over Denton Moor on 15th May. On
24th May the final sighting of the year took place when a lone Stork was
seen over Reva Reservoir. |
