Hawaiian Petrels Atop Haleakala

Fascinating seabirds!

As the sun sets off Maui, a pair of Hawaiian Petrels calls. Crow-sized seabirds with long, slender wings, the petrels sit at the mouth of their nest burrow, dug high in the rim of Haleakala volcano. To feed their young, adult petrels glide low over the dark ocean, snatching squid from the surface. This foraging flight may take two days, even a week. The petrels fly back to their nests at night, to feed a single chick. Hatched in July, the chick grows rapidly. By December, it will be ready to join the adult petrels for a life at sea.

Hawaiian Petrels Atop Haleakala

Written by Bob Sundstrom

This is BirdNote.

[waves on the beach]

As the sun sets off Maui, washing the ocean in crimson, a pair of Hawaiian Petrels calls. [“oo-ah-oo” calls of Hawaiian Petrel] Crow-sized seabirds with long, slender wings, the petrels sit at the mouth of their nest burrow, dug high in the rim of Haleakala volcano. 

[“oo-ah-oo” calls of Hawaiian Petrel]

One petrel flies out, winging rapidly toward the ocean. [wings] At the coast, it passes over a blowhole, where the sea explodes through a gap in the rocks.  

[“spouting horn”]

The petrel glides low over the dark ocean, snatching squid from the surface. This foraging flight may take two days, even a week. Then the petrel flies back to the nest at night, crossing above the surf line, [surf line] ascending to the mountaintop nest burrow.   

[“oo-ah-oo” calls of Hawaiian Petrel]

Here it feeds a single chick. [again, adult with chick] Hatched in July, the chick grows rapidly and in December will be ready to join the adult petrels for a life at sea. 

[wings followed by “spouting horn”]
