Range Description

Hemignathus flavus is endemic to O`ahu in the Hawaiian Islands (USA). It originally occurred throughout the island, but is now restricted to the two mountain ranges. In the Wai`anae Mountains, it is uncommon and sparsely distributed, mostly above 500 m elevation. In the southern and central Ko`olau Mountains, it is locally common, occurring from the summits occasionally down to 30 m in valleys, but it becomes increasingly rare northwards and is practically absent from the northern tip of the range (Lindsey et al. 1998). The population is estimated at 20,000-60,000 birds (Jacobi and Atkinson 1995, Lindsey et al. 1998), but surveys on O`ahu, unlike those on other Hawaiian islands, have not been systematic and these estimates may be too high (R. Shallenberger in litt. 1999). Christmas bird counts indicate a population decline over the period 1958-1985 (Lindsey et al. 1998), but more recent information indicates that the population may be stable and even increasing in some areas (Jacobi and Atkinson 1995, Lindsey et al. 1998).
