Rookery Survey 2009

Great response so far - well done for committing to the survey in March/April this year!

The 1964 list (number of nests in brackets) is more or less all covered now except for;
Hebden Bridge area -Hawksclough (16) , Albert Street (10) , Mytholm Church area (27).
The only other area from 1964 is the Luddenden Foot to Boulderclough area (49)
Please let me know, or post on the blog if you can take any of these on.

There are also some other general areas where we have no previous records of rookeries. We could do with some careful checks and counts of 'active nests' of these areas as below. Again please let me know if you can take any of these on.

Cragg Vale
Hebden Bridge to Midgeholme, Crimsworth Dean and Hardcastle Crags
Hebden Bridge towards Todmorden
Colden Valley from Hebden Bridge
Norland
Shibden Valley - upstream from Shibden Park
Brighouse/Clifton (east of Brookfoot as far as Kirklees Hall/ Cooper Bridge)

BTO advise that if colonies are 100m apart then we should class them as seperate colonies.
Many thank's everyone.

I can look at the Eastern end of Brighouse as well, Dave, as the 2 Rastrick sites initially show no activity at Delph Hill, and a 75% decline at Tofts Grove.

Thanks Mike - do you need a plan of the area with Calderdale boundary. I have one if needed. Also is there anything round the Woodhouse estate?

I've worked out the boundary on my OS maps, thanks, which interestingly wanders in and out of Kirklees. It puts my recent Yellowhammer just into Kirklees by a few metres !! A shame there's no public access to Kirklees Hall estate-it must hold some interesting stuff.
Will check out the Woodhouse and Bradley Wood areas too.
