Storm petrel explained

Storm petrel may refer to one of two bird families, both in the order Procellariiformes, once treated as the same family.

The two families are:

Northern storm petrels (Hydrobatidae) are found in the Northern Hemisphere, although some species around the Equator dip into the south.

Southern storm petrels (Oceanitidae) are found in all oceans, although only white-faced storm petrel (breeding in the North Atlantic, in addition to the Southern Ocean) and Wilson's storm petrels (on migration) are found in the Northern Hemisphere.
