one of a minimum of 14 birds at N Hykeham today….

This 1s bird was a right brute (presumably a male)…..2cy casps and michs are very similar in terms of plumage but note;

*’squarer’ head shape

*lack of ventral bulge (although some casps also lack this)

*duller bill (Casps bills get paler quicker)

*vestiges of a dark eye surround but mainly bleached/worn off now

This bird is missing most of its G covs thus revealing the dark underlying secondaries, the few central G covs that remain are bleached white.
