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.

Friday 21 September 2012

Almost all over...

Just when it was thought that the Yellow Wagtail passage was over this evening 11 birds were trapped during what was supposed to be a Pied/White Wagtail roost.  Three Pieds and two Whites were caught along with them and also a very juvenile looking  male Sparrowhawk.with the usual beady yellow eyes..



The last few days the evening sessions have swept up the remaining Reed and Sedge Warblers lurking in the reeds. Fat Scores of the Sedge Warblers a very impressive score of 50/60. The birds look like small thrushes.

As Luke mentioned on his blog some of these Yellow Wagtails look a little suspect..  Other races must pass though Southern England.  This evening one bird clearly had grey moulting through on the head rather than the usual colouring we are used to with the British flavissima wagtails. British yellow wagtails vary considerably but these birds are clearly different.with longer  wings and heavier weights.

A delicate subject. The more of these birds we catch the more questions we ask.
