Species group · Birds
WAnimals has 2 species of storm petrel, in the family Hydrobatidae.
Ranges calculated from the profiles that record the figure, not from all 2.
Each one has its own full profile. This group does not replace them: it brings them together.
No species documented in this group is genuinely at risk according to the IUCN, with the data available today.
Recorded in 27 countries. The ones with the most species in the group:
It weighs less than thirty grams and can live more than thirty years: one of the greatest mismatches between size and longevity of any bird.
From
It enters the colony only on the darkest nights, and pairs find one another among thousands of identical crevices by smell and by a purring call given from inside the nest for hours on end.
From
It seems to walk on water: it holds itself aloft on its wings while pattering the surface with its feet to stir up plankton, behaviour that gave the group its English name, petrel, in reference to Saint Peter walking on the waves.
From
It is one of the most abundant birds in the world, with tens of millions of individuals, and at the same time one of the least seen: it spends its life on the open sea and only comes ashore at night at Antarctic colonies.
