Détails de l'observation
Immature, second winter, potentially continuing. Species is scarce at Green Lane, far less common than similar-looking Lesser Black-back. This bird was the biggest gull present, whose size difference was pretty blatant regardless of where it moved. Its wingtips extended only minimally beyond its tail tip. Clean white head, whiter than the more slightly-built immature Lessers. Big bill, pink at the base with black tip. Digiscoped video:
