Paíño ventriblanco Fregetta grallaria

Small black-and-white storm petrel. Note distinctive sooty black upperparts and white belly and rump. Breeds across the South Pacific, South Atlantic, and South Indian Oceans, migrating north into tropics after breeding. Can be seen pattering its feet on the surface of the water when feeding for small squid and crustaceans on the surface. Distinguished from other storm-petrels by shorter legs that extend to the end of or just beyond the tail in flight, as well as by lacking the smudgy black stripe that cuts down the belly of the Black-bellied Storm-Petrel.
