I am undertaking a full Rook census in Buckinghamshire this year, attempting to map and count all of the rookeries. With this in mind, I will be very grateful for any records.
Between now and the end of March is the best time to count, as the trees are still not in leaf and the nests are easily visible. The information I require is thus -:
1) Location of Rookery with 6 figure OS grid reference
2) Exact number of active nests (eg, occupied nests)
3) accurate count of Rooks present in or around colony
If you know of a Rookery but can't get over to check it, let me know it's location and I will get round to surveying it
I shall present a detailed summary of results which will be sent out to all contributors
Please email me on LGREUK400@aol.com with any information
Many thanks
Lee
