Notes on Imitator Sparrowhawk Accipiter imitator and Pied Goshawk Accipiter albogularis on Bougainville

Abstract

There is much to learn about these two little-known goshawks and there is a ‘clear need’ to understand the plumage, vocalisations, ecology, biology and field identification of these two species. Here is presented an addition to our knowledge of these species and comments on the Accipiter albogularis/imitator debate based on recent observations of these two species on Isabel and Bougainville.
