Papuan Swiftlet Collocalia papuensis

Justification
This species is known from only a handful of specimens and may be unidentifiable in the field. Although it may be locally common, there is no information on its likely distribution extent, population size, trends or threats. For these reasons, it is classified as Data Deficient.

Distribution and population
Collocalia papuensis is known from a handful of specimens from New Guinea (Papua, formerly Irian Jaya, Indonesia and Papua New Guinea). Specimens are known from the Idenburg River (where flocks of up to 30 birds were recorded), northern Snow Mountains, around Jayapura and one taken in 1993 from a cave in the Hindenburg Range. There are unconfirmed sight records across northern Papua New Guinea to the Huon Peninsula but this species may be unidentifiable in the field (Coates 1985, Beehler et al. 1986, Rowland 1994).

Population justification
The global population size has not been quantified, but the species is described as locally common (del Hoyo et al. 1999).

Trend justification
The population is suspected to be stable in the absence of evidence for any declines or substantial threats.

Ecology
Its ecological requirements are unknown and it has been recorded from sea-level to 2,400 m.

Threats
The population, status and threats to this species cannot be assessed on present knowledge.

Conservation Actions Underway
None is known. Conservation Actions Proposed
Survey historical locations and potentially suitable habitats for the species. Study its ecological requirements and threats. Clarify field identification criteria.
