摘要

We present methods to determine the age and sex of Akohekohe (Palmieia dolei), an endangered Hawaiian honeycreeper, developed on the basis of 45 museum specimens and 91 live birds captured on the island of Maui. Akohekohe retainec all juvenal primaries, some juvenal secondaries, and some body feathers after the first prebasic mo they attained full adult plumage after the second prebasic molt. Retention of brown juvenal body feathers, especially on the head, distinguished most birds in the first basic plumage from adults, which have a full complement of distinctive, black lanceolate body feathers with white, gray, or orgnae tips.
