1 cy Barred Warbler / Hauksanger


One each of Sedge Warbler and Reed Warbler today, both were adults (2cy+). Adults are quite scarce in the catch, therefore we taken the opportunity to show the ageing criteria: Both species moult in the winter quarters, and can be aged on the very worn plumage when trapped in August. Wear is often most obvious in tertials, greater coverts and tail.

Quite a few siskins have turned up the last days, a species we normally don't catch in any numbers at Revtangen. All have been 1cy birds.
