Are you sure you're a Willow Warbler?

Very calm and overcast with the gentle caress of the breeze coming from the west gave excellent ringing conditions through the morning; it wasn't as profitable as previous days however with 44 new birds caught encompassing the usual spread of migrants with a Garden Warbler, 2 Whitethroats, 11 Lesser Whitethroats, 14 Willow Warblers, a Redstart, 4 Blackcaps and 4 Chiffchaffs in the total.

Garden Warbler and Redstart

 

A few Barnacle Geese on the move through the morning and 3 Whimbrel at Kroghage in the afternoon was all I could come up with to supplement the blog today I'm afraid!

This interesting Willow Warbler was among those caught today; it appears to have just undergone a winter partial moult rather than the normal complete moult with un-moulted tertials, greater coverts and median coverts with a mix of old and new lesser coverts.  Both wings were the same.
