Range and Habitat
Mottled Petrel: Breeds on islands off New Zealand. Spring and summer visitor to Bering Sea and cool northeastern Pacific; rarely south to Oregon and California. Pelagic, only comes ashore to breed.
The Mottled Petrel was discovered in the South Pacific Ocean during Cook's second voyage. A painting was made by George Forster and a description drawn by his father J.R. Forster.
It was formerly more numerous than today. Numbers were affected by predation by introduced mammals.
This petrel does not follow ships and usually remains far from land.
A group of petrels are collectively known as a "gallon" and a "tank" of petrels.
