Wilson's Storm-Petrel, Oceanites oceanicus

Wilson's Storm-Petrel
Storm-Petrels are always a challenge to photograph; my only exception has
 been a fabulous occasion with some Forked-tailed that foraged under a pier.
I'd love to have similar luck with Wilson's some day; in the meantime, I'll
have to make do with these, taken out at sea.
