Like many legends, there’s most likely a grain of fact. Wilson’s Storm-Petrels are tiny seabirds weighing simply over an oz.. Throughout a gale, hiding beside a big ship might present slightly shelter from the gusts.

Wilson’s Storm-Petrels happen in each ocean, preferring chilly, salty water wealthy in plankton. Their toes patter throughout the floor to fire up small prey objects reminiscent of krill and small fish. When touring, they typically glide on highly effective ocean winds.

Wilson’s Storm-Petrels breed on the cliffs of islands within the southern oceans, South America, and Antarctica, the place they generally nest so far as 70 miles inland. In contrast to most seabirds, they elevate their younger in burrows, maybe giving them some safety from predators like skuas and gulls.

The storm-petrels’ reliance on chilly, salty water for meals might make them an early warning signal of types, although not in the way in which these sailors thought. Local weather change is altering ocean temperatures and salinity. Shifts in storm-petrel feeding conduct on the floor might replicate adjustments in ocean circumstances under.
