Taxonomy & Nomenclature
Synonym/s: Acrocephalus atyphus astrolabii Holyoak & Thibault, 1978; Acrocephalus luscinia astrolabii Holyoak & Thibault, 1978
Conservation Status
Extinct
Last record: c.1835
IUCN RedList status: Extinct
Distribution
Unknown (Yap Island, Caroline Islands, Micronesia?)
Apparently only known from 2 specimens collected during the early 19th century. The type locality is not known for certain, however the broad geographic area is believed to be the Marianas Islands. However, the Gambier Islands have been recently proposed as the type locality (Cibois et al. 2011).
Biology & Ecology
Hypodigm
Two specimens may exist.
