| 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. |
