Oceanitidae

Storm Petrel

The Oceanitinae is one of two subfamilies of storm petrels. Because the distribution of the subfamily is predominantly in the southern hemisphere they are sometimes known as the southern storm petrels. The subfamily contains five genera in which there are eight species. They were the second group of storm petrels to break off from the ancestral petrel stock, and for this reason some authors have suggested that they should constitute a separate family from the Hydrobatinae storm petrels.

According to the IOC there are just 9 Austral Storm Petrels in the newly split family of Oceanitidae, which are:

Wilson's Storm Petrel Oceanites oceanicus
Elliot's Storm Petrel Oceanites gracilis
Pincoya Storm Petrel Oceanites pincoyae

Grey-backed Storm Petrel Garrodia nereis

White-faced Storm Petrel Pelagodroma marina

White-bellied Storm Petrel Fregetta grallaria
Black-bellied Storm Petrel Fregetta tropica
New Zealand Storm Petrel Fregetta maoriana

Polynesian Storm Petrel Nesofregetta fuliginosa

Oceanitinae is one of two subfamilies of storm petrels. Because the distribution of the subfamily is predominantly in the southern hemisphere they are sometimes known as the southern or austral storm petrels. The subfamily contains five genera in which there are eight species. They were the second group of storm petrels to break off from the ancestral petrel stock, and for this reason some authors have suggested that they should constitute a separate family from the Hydrobatinae storm petrels.

Austral Storm Petrels Oceanitidae

Family Account

Storm-petrels are small aerial seabirds found in all oceans of the world. Recently they have been split into two families, as genetic evidence reveals that ancestors of northern and tropical species diverged from ancestors of austral species about 30 million years ago.

Cornell Species Account

The Black-bellied Storm-Petrel is very closely related to the White-bellied Storm-Petrel (F. grallaria), as the name implies their belly color is different but they also differ in the average water temperature they choose.

Black-bellied Storm Petrel Fregetta tropica

Species Account

Black-bellied storm petrels are found throughout the Southern Ocean, where they breed on many subantarctic islands, and may sometimes be seen off the southern New Zealand coast during the breeding season.
