A Bank Holiday walk around Paxton Pits this afternoon was rewarded with these great images of a warbler feeding its nestlings with a great variety of flying insects. I was sure that it was a Willow Warbler but everyone who looked said eye-stripe therefore Sedge Warbler. However, I am not convinced as there is no streaking on back or breast. I will post it on the bird ID Forum that I subscribe to so more to follow.
It is a Willow Warbler - identified on the Bird ID site.
