A short while ago this evening whilst in the kitchen preparing my evening meal I noticed some 40 - 50 Herring Gulls wheeling overhead in what I at first took to be a rather aimless fashion. After some observation however it appeared that they were in fact feeding on flying insects as they would momentarily pause in mid-flight and snap their beaks. This continued for about 30 minutes.
Has anyone else observed this behaviour in Herring Gulls?
