Wilson's Storm-Petrels are the smallest animals breeding on the
Antarctic continent and on antarctic
islands
in the southern summer.
From there they migrate northward after the breeding season, into
all southern oceans. In the southern winter they will reach all
tropical waters around the globe and move on to the northern
hemisphere.
In the Atlantic Ocean they are found as far North as Spain and
the American East coast, in the Pacific Ocean well North of Hawaii
and in the Indian Ocean they reach the coastlines of the sub-continent.
Around Australia Wilson's Storm-Petrels can be found basically
anywhere at sea
during their migration, except for the Coral Sea with the Great
Barrier Reef and the northern tropical waters (Arafura Sea and
Gulf of Carpentaria), where they are rarely seen.
When not breeding, Wilson's Storm-Petrels will mostly stay on the high seas, but they do also
enter coastal waters.
They breed on offshore
islands.
