Barnacle Goose, with Brent Geese, Blennerville, 31st December 2015 (Hubert Servignat).
Quite possibly the same bird which appeared alone and exhausted at Black Rock in October (see post HERE), then appeared healthy and well with the Brent Goose flock at Carrahane a week or so later. About 150 Barnacle Geese are currently wintering on the Magharee Islands, the highest number there in well over a decade.
