What was the SIZE of the White Swallow-like bird you saw in Atlantic Coast?



White-faced Storm-Petrel: The only Atlantic storm-petrel with the combination of dark gray upperparts and white underparts with a dark cap and eyeline. Long black legs trail behind squared tail in flight. Webbing between toes is yellow. Alternates rapid, shallow wing beats with stiff-winged glides.
