LC
Apapane Himatione sanguinea



Justification

Justification of Red List Category
Although this species may have a restricted range, it is not believed to approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Population justification
The global population size has not been quantified, but the species is described as the most abundant Hawaiian honeycreeper (Douglas Pratt 2005).

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

Distribution and population

Himatione sanguinea is endemic to the Hawaiian Islands (Kauai, Oahu, Lanai, Molokai, Maui) U.S.A. (del Hoyo et al. 2010). The subspecies freethii was endemic to Laysan, but became extinct in 1923 (E. VanderWerf in litt. 2011).
