Jay (Garrulus glandarius)
The Jay is not an uncommon bird nationally but I rarely seem to encounter them down here in Dorset. They are certainly about seem less frequent than elsewhere but then, apart from the Wareham/Puddletown Forest area, I suppose we do not have that much suitable woodland.
Jays are well known for two things. Firstly, they like to roll around in Wood Ants nests to get the acid they spit onto their feathers. They are also great hoarders of nuts in the autumn to tide them over until spring comes.
Good to look at but aggressive, bad tempered birds in general!
