Beck's Petrel

Beck's petrel, a small seabird with the scientific name Pseudobulweria becki, is a creature of the open ocean. It is adorned with dark brown plumage on its upper parts, including the head and throat, while its underwings are similarly dark. A striking white wingbar contrasts against this dusky canvas. The belly and breast of the bird are a pristine white, and it soars with straight wings that gracefully arc back at the tips.

Identification Tips

When observing Beck's petrel, look for its relatively small size compared to similar species. The dark upperparts, combined with the white underparts, are distinctive. The white wingbar is fairly distinct, and the wings are shorter and broader than those of the Tahiti petrel, a similar species. The pale throat is another feature to note for identification.

Habitat

Beck's petrel is believed to favor nesting on small, remote islands that boast tall mountains within the Melanesian region.

Distribution

This elusive petrel was historically known from only two specimens found near New Ireland, Papua New Guinea, and the Solomon Islands. Recent sightings suggest it may still inhabit areas around the Bismarck Archipelago and Solomon Islands.

Behaviour

The petrel is migratory, often traveling far from its breeding grounds once the young have fledged. A disoriented individual was once found on a cruise ship, indicating that these birds can be found at sea, sometimes attracted by artificial lights.

Breeding

The exact location of Beck's petrel's breeding grounds remains a mystery. However, the evidence points towards the southern Bismarck Archipelago. The species is known to be migratory, and it is likely that they breed in Melanesia southeast of New Guinea.

Similar Species

The Tahiti petrel is a similar and more common species that could be confused with Beck's petrel. However, Beck's petrel is smaller, with a pale throat and shorter, broader wings.

Conservation status

Beck's petrel is considered critically endangered by the IUCN. Sightings in the 2000s have confirmed the species' continued existence, but it remains at high risk of extinction.
