Cassiobury Park - 18.9.12

At least 10 Jay were in the park including 8 circling high over trees by the croquet lawn first thing. Not something i've seen them do before. 4 Swallow headed SW with a Meadow Pipit soon after. A Chiffchaff was by the yard as was a Sparrowhawk that was soon mobbed by Jackdaws and Starlings.
