How do Wilson’s Storm Petrels feed?

Wilson’s Storm Petrels have the ability to hover just above the water’s surface in order to pluck at plankton just underneath. Their feet will dip in at a spot in the water (perhaps to attract prey), the bird will nab the food, and then it will flutter to a new spot a little ways away.

They will also sometimes make rare dives in order to nab small fish.

What are Wilson’s Storm Petrel birthing rituals like?

Wilson’s Storm Petrels mature sexually at around 4 years of age.

Nesting occurs between November through May, the exact starting time depending somewhat on where in the world a particular bird is located. Colonies are located close to the sea. Nests are built in crevices in rocks or in burrows in the earth. A single white egg is laid.

The adults go foraging for food only at night in order to avoid detection by predatory birds such as Gulls and Skua. They find their nests in the dark by smell.

Both parents will take turns incubating (about 2½ months) the egg and then feeding the chick once it has hatched. Chicks are brooded for about 2 months.

Hatchlings will finally leave the nest anywhere from 50 to 100 days after hatching, the time seeming to depend on how much they were fed during the brooding period.

How long do Wilson’s Storm Petrels live?

Wilson’s Storm Petrels can live for up to 20 years in the wild.
