Overview
The Grey Plover is an Arctic breeder that winters on the Sefton Coast's mudflats and lagoons. Stockier than Golden Plover, it tends to be solitary or in small groups rather than the huge flocks of its cousin. The black axillary feathers ('armpits') visible in flight are distinctive. In April departing birds may be starting to show the black belly of summer plumage.
