Buteo solitarius breeds on Hawai`i in the Hawaiian Islands (
USA), with vagrants recorded on Maui, O'ahu and Kaua'i. The population is thought to be fairly stable (J. Nelson
in litt. 2007)
, and estimates range from 1,457 (Klavitter
et al. 2003)
and 1,600 (1,120 adults) to 2,700 birds (Hall
et al 1997, Griffin
et al. 1998)
. The lack of information on historical numbers makes an assessment of this species difficult, and the underlying trend may be of gradual decline as nesting habitat disappears (J. Klavitter
in litt. 1999). The rapid occupation of abandoned breeding territories suggests that the species may now be at or near the carrying capacity of remaining habitat (J. Nelson
in litt. 2007)
