But in regular "migration weather," warm and foggy, birds often appear to lose their way, and anything may turn up. One Norfolk naturalist fell in with a whole flock of bluethroats, and certain Lincolnshire ornithologists, who regularly work the fringe of thickets behind the foreshore or at the back of the dunes at migration time, know from experience that there is no rare warbler, European or even Asiatic, whose occurrence is beyond the bounds of possibility.
