Justification
This rare and little-known species, endemic to New Guinea, is known only from a handful of records. There is no information on its likely distribution extent, population size or trends, although there are unlikely to be intense threats within its distribution. For these reasons, it is classified as Data Deficient.

Distribution and populationErythrotriorchis buergersi is a rare and little-known species, endemic to New Guinea (Papua, formerly Irian Jaya,
Indonesia and
Papua New Guinea). It is known only from a handful of records, none in the last ten years, all from eastern New Guinea except for a single record from the Foya Mountains in Papua (Pratt 1982, Coates 1985,
Diamond 1985,
Beehler
et al. 1986, K. D. Bishop
in litt. 1999, P. Gregory
in litt. 1999). Although it is likely to be overlooked, it does soar (Diamond 1985,
I. Burrows
in litt. 1994)
and appears to occur at very low population densities.
Population justificationThe global population size has not been quantified, but the species is described as rare (Ferguson-Lees and Christie 2001).
Trend justificationThe population is suspected to be stable in the absence of evidence for any declines or substantial threats.
EcologyHill and lower mountain forest, probably generally lower than
Accipiter meyerianus, at 450-1,580 m.
ThreatsMost of its habitat is unsuitable for logging and it is unlikely to be hunted (B. Finch
in litt. 1994)
, however its status cannot be assessed from the present few records.
Conservation actions underwayCITES Appendix II.
Conservation actions proposedSearch for the species in potentially suitable mountain forest in New Guinea. Study its ecological requirements and threats.
