Blaukehl-Nektarvogel Anthreptes reichenowi

Small, short-billed, warbler-like sunbird. The distinctive male has a blue bib. The female is drab but can be identified by its small pale eyebrow, greenish back, and overall size and shape. Found in forest at low elevation, mostly close to the coast. Often in forest understory; less conspicuous than a typical sunbird. Most distinctive vocalization is a rapidly repeated “tchew”. Shape, size, and olive-green back separate Plain-backed from other sunbirds.
