Range Description

Vestiaria coccinea formerly occurred on all the main islands in the Hawaiian Archipelago (USA) but it is now extinct on Lana'i and relict populations (probably fewer than 50 individuals [J. Lepson in litt. 2000]) remain on O`ahu and Moloka`i (Scott et al. 1986, P. Donaldson in litt. 1999). Recent population estimates are: c.385,000 individuals, excluding birds on O`ahu, during 1976-1983 (Scott et al. 1986) and more than 350,000 individuals in the early 1990s following recent declines in several populations (Jacobi and Atikinson 1995). There is now evidence from monitoring (much of it unpublished) that the species has declined throughout the Hawaiian islands, except on windward Mau`i and at Hakalau, Hawai`i, where the populations appear to be stable (D. Pratt in litt. 2007). The numbers of individuals detected during monitoring have fallen at both mid and low elevations (D. Pratt in litt. 2007). The apparent decline appears to have been most pronounced in western Hawai`i, although there is little quantitative data for this area (D. Pratt in litt. 2007).
