Herald petrels are found in several, disjunct regions. The subspecies P. a. arminjoniana occurs in the south Atlantic near Trinidade and Martin Vaz Islands and in the Indian Ocean at Round Island in Mauritius. Some authorities do not place the Round Island populations in this subspecies, however. The subspecies P. a. heraldica is found in the southern Pacific, from northeastern Australia and throughout the tropical Pacific to Eastern Island.
