This morning Montpelier was descended upon by up to 10 Jays, flying over the rooftops in Richmond Road and perched in trees in the park and station. They were very noisy and I noted 3 vocalisations: 1) the normal raucous screech 2) a peevish growling noise reminiscent of a rather annoyed tom cat and 3) an almost peacock-like cry. I'm used to seeing very conspicuous urban Jay behaviour in the autumn as they go about caching food etc, but I've never seen a spring equivalent. Perhaps they were partial migrants?
A pair of Long-tailed Tits were at the station for the second morning running - they might be nesting!
