Great Black-backed Gull is quite a scarce species in the Algarve; in 2008, the last year for which an annual report has been published, there were just four records here.
In most years, birds occur between November and February, usually singly; sub-adults predominate. With thousands of large gulls wintering here and relatively few observers, it is probable that a few get overlooked.
The favoured sites are the ‘docapescas’, the fishing docks, at Sages, Portimão, Quarteira and Olhão. This bird found yesterday at Sagres harbour fits the pattern exactly.
