Behavior

Food and feeding

The diet consists mainly of planktonic crustaceans and tiny fish, which they catch by either seizing prey while on the surface or by dipping their bill into the water while in flight.

Breeding

They breed colonially and prefer small islands. Nests are situated in soil, hidden by vegetation, and dug with the bill or feet, or in a hollow in a crevice. When coming back to their nest at night, they will coo softly and listen for their mate.

Conservation

Widespread and common throughout its large range, with an estimated population of 5,000,000, the fairy prion is evaluated as least concern on the

IUCN Red List of Threatened Species The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological spe ...
