The cold wind has suppressed much of the bird song over the last couple of days, with one notable exception - yesterday afternoon a couple of visitors heard an unfamiliar song, and then found themselves looking at a male Dartford warbler! If their report and description are accepted, I think this will be the third county record.
In fact, such a sighting is not as unlikely as it may seem at first. Dartford warblers have been spreading northwards, colonizing suitable habitat some distance from their usual strongholds on southern and eastern heaths, and they have to fly over lots of unsuitable habitat on their way. Nevertheless, it is very unusual to actually find one away from breeding habitat.
Several people were out searching this morning, but the bird has either moved on or was keeping its head down in this rather wintry weather.
