The White-bellied Storm Petrel, Fregetta grallaria, or white-bellied storm petrel, is a congregating bird, either in nesting areas or at sea, mostly in small or loose groups, although some species act alone. They spend their entire lives at sea, returning to land only to breed. With the exception of a few species that land during the day, most species return to their nests after dark to reduce prey from predators such as gulls, skuas, crows and birds of prey. They often fly close to the sea, as agile as swallows, and sometimes their feet touch the water, as if walking on water. Occasionally dives into the water to hunt, but soon jumps out again. Rarely stop to rest on the surface of the sea.

The white-belly petrel has a small mouth crack and can only prey on small fish and squid and krill floating on the sea surface. Often splashing or swaying on the water with their feet, feeding on disturbed and alarmed zooplankton and small fish. Sometimes they follow fishing boats, whale and dolphin herds, or schools of fish to hunt for small, fleeing fish.
