Hawaiian Petrel

The Hawaiian petrel or ʻuaʻu (Pterodroma sandwichensis) is a large, dark grey-brown and white petrel that is endemic to Hawaiʻi. == Distribution == The Hawaiian petrel was formerly found on all the main Hawaiian Islands except Niʻihau, but today it is mostly restricted to Haleakalā crater on Maui; smaller populations exist on Mauna Loa on the island of Hawaiʻi, Waimea Canyon on the island of Kauaʻi, Lānaʻihale on Lānaʻi, and possibly Molokaʻi. It was formerly lumped together with a very similar species from the Galapagos Islands. In 2013 a specimen was retrieved from Arizona near the Colorado River, marking the first inland North America record of this species. On August 7, 2023, a Hawaiian petrel was reported near Cape Arago, proximate to Coos County, Oregon. It is not the first record of the species in the state, and there are also reports of it from California. == Behavior == === Feeding === Their diet consists of 50–75% squid, and smaller percentages of fish and crustaceans. === Breeding === These birds nest in burrows or rock crevices. Their breeding season extends from March to October. The female lays one white egg. When the chick hatches, the parents go out to sea…
