Many thanks to those who have already offered to take part.
Several areas are now allocated but we need more help with the following areas from the 1964 survey which was undertaken by Halifax Scientific Society. (1964 nests in brackets)
Sowerby Bridge to Triangle (49)
Millbank (7)
Denton Bridge area (357)
Rishworth (88)
Hawksclough (16)
Hebden Bridge - Albert Street (10)
Mytholm Church (27)
Luddenden Foot to Boulderclough (49)
Exley Bank (17)
Exley - Chevinedge (4)
Elland - Elsinore Avenue (2)
Greetland (31)
Holywell Green (44)
Rastrick - Delf Hill/Crowtrees Lane (25)
Rastrick - Field Lane/Tofts Grove (130)
Other areas may have colonies but there is no reference in the 1964 survey so the following also need to be checked. Nil counts are just as important;
Copley, Stainland, Barkisland, Shibden Park and the valley up from Stump Cross, Sowerby/Beechwood, Cragg Vale, Hebden Bridge to Midgeholme, Hardcastle Crags, Crimsworth Dean, Colden Valley etc.
The 1964 survey did not include areas up the Calder Valley beyond Hebden Bridge. As this is part of Calderdale it would also be good to cover;
Hebden Bridge to Todmorden, Todmorden to Cornholme/Portsmouth (Burnley Road), Todmorden to Walsden, Todmorden - Harley Wood/Woodlands Avenue etc. etc.
Birds are starting to be active at colonies now so it's a good time in March to start having a look and take initial count and then count again before the leaves come on in April/May.
Q 1 - is there a colony present?
Q 2 - Estimated number of 'Apparantley Ocuupied Nests' (this is the criteria suggested by the BTO)
Q 3 - Precise location (grid reference if possible but not essential as I hope to be able to forward all the information to the BTO Atlas survey at the end of the season)
Please email or text or post a message on the blog as soon as possible if you can commit to an area and thereafter forward all the information to me. The more volunteers take part, the better.
Many thanks on behalf of Calderdale Bird Conservation Group.
