Myself and Roy Hargreaves visited late this afternoon to watch the gulls and this DARK-BELLIED BRENT GOOSE was just off the car park steps. In fact it must have been the first bird Roy saw as I was still setting up my 'scope when he picked it out. After a while it joined up with a small flock of Greylags and on several occasions took flight and did a few circuits of the reservoir. Including one when it ventured in to Bucks air space, just as Rob Andrews turned up. Couple of pictures above when it was reasonably close. Last seen sat in the middle of the reservoir off the jetty, as it got to dark to see (Dave Bilcock).
