INTRODUCTION

This is foreseen to be an occasional blog relating to bird ringing at Abbotsbury Swannery. The site has operated as a BTO Constant Effort Site since 1995 and has taken part in the BTO Swallow Roost Project. In recent years we have concentrated in the autumn with both Yellow and Pied/White Wagtails. In 2009 we joined the Woodcock Network.

Colours,colours....

A senior moment the other evening. The wagtail was a Blue-headed Wagtail not a Grey-headed Wagtail. These things happen as you get older. It was still a nice bird. Of equal interest that night were the half dozen or so apparent female yellow wagtails which were biometrically much larger in weight, wing length and physical appreance. Very white on the chin and facial markings quite different from the yellow wagtails which we caught that evening. Young Yellow Wagtails vary considerably but these birds were quite different.

Hopefully this week we can catch some more and unravel the mystery. The weather looks favourable mid-week to the end of the week
