This landed in a tree in Christopher's next door neighbour's garden and I just happened to be standing on the balcony at the back of the house. This is my best photo yet of a parakeet. They're very common in that part of the country (so no-one gets excited!) but there aren't any where I live.
@thresheg Thanks Graham. People in the south east think they're a nuisance but I think they're beautiful and I get very excited on the rare occasions that I see one - usually a long way away.
