Two
pairs bred in one area rearing three and one young respectively
with a pair in another area rearing three young (PR).
The
area surrounding the Barden watchpoint provided the lions share
of records of birds reported every month of the year with a
bird seen carrying food in June indicating that breeding is
likely here also. Monthly maxima at this site included six
in May, eight in April and 11 in August.
Sporadic
records came from sites in the Washburn Valley such as Kex Gill
Quarry, Timble Ings and Sword Point plantation and in the south
of the area singles were seen at Leeshaw Reservoir in April,
Elland Gravel Pits in May, Fly Flatts in June and Hollins Hill
in December.
It doesn’t seem that long ago that this species was a rarity in the recording
area – long may this trend continue. |
2004 |
This species
now seems to be well-established as a breeder, and this was our
most successful year to date.
In one part of Wharfedale, five pairs successfully fledged young (PR). No breeding
data was received for another section of Wharfedale, but from behavioural observations
it is likely that as many as six pairs attempted to nest there. The Washburn
Valley had its first breeding success in living memory, with three chicks being
fledged (AJ, PR). The young were ringed with the assistance of Yorkshire Water
climbers . Display was noted at two further sites in the Washburn, and in April
it was possible to see up to 16 birds in the air at one time, whilst in Wharfedale,
a heavily-watched part of the recording area, it is not uncommon to receive records
of double figures at any time of the year. |
2005 |
The 1995
Group Report described it as being an excellent year for the
species. Such is the exponential growth since then, that the
maximum number of birds now seen on a single day is getting on
for the yearly total ten years ago.
This year,
330 records were submitted, with sightings throughout the year,
although most came from the north-west sector, and, in particular,
Barden Scale. This location had daily double figures in every
month but July, October and December, and on 6th September
no less than eighteen different birds were seen, a record for
the Group (AGG).
As with many
other birds of prey, particularly those prone to wandering,
estimating total numbers is difficult. However, from the detailed
records submitted, it is thought probable there were also at
least thirty birds in the Washburn Valley, and eleven in Lower
Wharfedale. There seem to be increasing numbers of records
from the south of the recording area, which this year included
several individuals seen on the land between Thornton Moor
and Midgley Moor, and even urban outskirts : Shipley Glen,
Elland Gravel Pits and Thornton.
Breeding
successes mirrored the increase in the number of sightings,
and were at least on a par with 2004. In Wharfedale, four pairs
raised a total of six young, with the distinct probability
that birds had bred elsewhere in the dale, based on observations
of behaviour. Birds again bred in the Washburn Valley, where
seven young were raised from three nests, and a nest was constructed
at a further site, but abandoned. As with Wharfedale, the presence
of other pairs, often including displaying birds, strongly
suggested there were other breeding attempts or successes. |
