One of the Lesser Black-backed Gull
chicks ringed on Burhou in July 2010, and which was recorded by Michael Davis at Quarteira, Faro, Portugal
of that year was reported by Clive Barlow from Tanji Bird Reserve, The Gambia
on 15 February 2012 - a straight line distance of 4,256 km! Although a small minority of LBBGs from Western Europe are known to winter this far south, this is the first evidence that Channels Islands birds make such long migrations. The photos below show just how advanced this gull is in its moult...and the Clive Barlow's photo shows the gull in rather illustrious company at Tanji!
I am very very happy with this amazing report!
