Cassiobury Park - 18.9.13

A male Mandarin was reported on the canal to me first thing but the only other bird of note was while I was having my lunch. The door was open and I thought I heard a Raven 'cronking' but as soon as I stepped out the door it had stopped. But then as soon as id sat down again it called again! This time I picked it up circling fairly high and even managed to get my work mates on it before it headed off east.
