Thanks for the post Rob. I've copied it to the the existing county Rookery thread where it is much appreciated. If you need to find that thread again (and it's not on the first page of the forum) just use the search engine on the toolbar at the top of the forum page
hi, im reasonably new to birding and i still need to carry a book to reference to but i am getting better each trip. The other day i managed to track down a very large rookery in happy valley the best view is from the entrance on jacksons lane next to norbury athletics pitch , walk down the path until you reach the end of the football pitch and they roost the other side of the river directly infront. Its an amazing sight around four ish there are thousands of them flying in formations/displays. Thanks Rob
