📖 1. Overview
The Satin Bowerbird is a medium-sized bird living along the eastern and southeastern coast of Australia, famous for males building courtship 'bowers' of twigs and decorating them with blue objects.
🦴 2. Anatomy & Morphology
Adult males have glossy blue-black satin plumage, a bluish-white bill, and violet-blue eyes. Young males and females have olive upperparts with scaly underparts and are called 'green birds'; males do not acquire full adult plumage until about 7 years of age.
🔍 3. Ecology & Behavior
It feeds mainly on fruit all year round, taking insects during the summer breeding season and leaves in winter. Males build a two-walled avenue bower of twigs on the ground, decorate it with blue objects, and dance before females, while the female builds the nest alone and incubates 2–3 eggs for about 21 days.
