📖 1. Overview
The Budgerigar is a small parrot native to the dry interior of Australia and the most widely known pet bird in the world. Wild individuals have green bodies and yellow heads.
🦴 2. Anatomy & Morphology
It is small and streamlined with pointed wings and tail. Wild individuals have a yellow forehead and throat, yellow-and-black striping on the head, purple and black cheek markings, and an upper mandible whose tip extends over the lower mandible.
🔍 3. Ecology & Behavior
It picks grass seeds and crop grains off the ground and dehulls them before eating, and stays near water holes because it drinks about 5.5% of its body weight in water daily. It lives in large flocks and breeds after rains when food becomes abundant.
