Called in for the Gull roost on the way back from Shrewsbury.
A little later as the roost started to build I saw an Adult Iceland (Gaviota Groenlandesa / Larus glaucoides), Adult Yellow-legged (Gaviota Patiamarilla / Larus Michahellis), Black-headed (Gaviota Riedora / Larus ridibundus), Herring (Gaviota Argéntea Europea / Larus argentatus), Great Black-backed (Gavión Atlántico / Larus marinus) and Lesser Black-backed Gull (Gaviota Sombria / Larus fuscus).
