Red-headed Parrotfinch Erythrura cyaneovirens


Taxonomic note
Erythrura cyaneovirens (del Hoyo and Collar 2016) was previously split as E. cyaneovirens and E. regia following Sibley and Monroe (1990, 1993)

Population justification: The global population size of the pre-lump E. regia likely fell in the range 2,500-9,999 mature individuals based on an assessment of range size, known records, and descriptions of abundance, with less than 1,000 mature individuals per sub-population. However, the Samoan populations of the newly defined E. cyaneovirens are widespread, if uncommon (Payne 2016). Based on known records, population density estimates of congeners and closely related species, and assuming only a proportion of its range is occupied, the Samoan sub-population sizes are likely more than 1,000 mature individuals, and the global population of the newly defined species possibly may be greater than 10,000 mature individuals. Therefore, it is placed here in the range of 10,000-19,999 mature individuals.

Trend justification: The population is suspected to be in decline as a result of habitat loss in at least part of its range.
