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 There is now evidence from monitoring (much of it unpublished) that the species has declined throughout the Hawaiian islands, except on windward Mau`i and at Hakalau, Hawai`i, where the populations appear to be stable (D.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)
