The White-necked Petrel is a seabird from the petrel family. It lives in the open ocean and arrives at the islands only to raise its chicks.
The White-necked Petrel differs from other petrels by its bright white neck. It is important for nature as a carrier of nutrients from the ocean to the islands and as an indicator of the health of the marine environment.
Immature form that undergoes metamorphosis before adulthood.
