Last Friday, a Slender-billed Gull was found at Ria de Alvor by Guillaume Réthoré, Willem Scheres and Julio Reis during a wader count. This species is more common in the eastern part of the Algarve and recorded less than once a year a Ria de Alvor. 580 waders of 18 species and 64 Flamingos were also recorded at that time, for a total of 50 species spotted in 3 hours.
2 Lesser Black-backed Gulls from Guernsey and a Ringed Plover ringed in Wales were controlled, showing (if still needed) that birds are moving south.
