Bosherston Lakes this afternoon

A walk around the lakeside paths on another extremely mild afternoon produced a couple more firecrests - along the lower east arm and along the western arm path. The latter one in a mixed flock of titmice, goldcrests and at least one chiffchaff.

Lots of hirundines were feeding over the lake in increasing numbers. By 1700 hrs there must have been close to 500 feeding over the central lake and western arm. Around 90% were swallows but there were also small numbers of (lateish) house martins and sand martins in the flock. They were still flying into the area over Home Farm buildings less than an hour before sunset - perhaps they roosted in the central lake reedbed?

We ended the day watching c. 500 greater horseshoe bats emerge from their roost.
