Snow petrel, Pagodroma nivea
From a clifftop I watched a snow petrel darting to and from a nest below. The sparkling ocean backdrop was too bright for me or my camera autofocus system to ‘see’ the white bird. I pre-focused instead when the background was land and continued tracking and shooting by instinct to get this shot.
