A review of Jouanin's Petrel records in the eastern Indian Ocean

Abstract

Jouanin's Petrel Bulweria fallax mainly occurs in the western Indian Ocean. Prior to our study there were only two records from east of 82° E. We show that small numbers of Jouanin's Petrels are regular visitors to the eastern Indian Ocean, occurring to 15° N 90° E in the Bay of Bengal and 15° S 123° E off northern Australia. Although seasonal coverage is limited, they have been recorded east of 80° E from April–July and October–December, but not in February–March. Most sightings are from oceanic waters at least 20 km offshore where depths exceed 500 m.
