A complex mimic: rattles, whistles, clicks, and squeaks mixed with imitations of other birds. Song is a continuous medley. Also gives harsh 'scheer' alarm and chattering.
Southern Cassowary
Produces very deep, booming rumbles and low-frequency calls below 20 Hz (infrasound), felt more than heard. Also gives loud bellowing grunts audible up to 1 km away.

About These Birds
Common Starling
Estorninho-malhado (Sturnus vulgaris) — 19-22 cm. Distribuído pela Europa e Ásia, introduzido na América do Norte, Austrália e África do Sul. Plumagem negra com reflexo metálico verde e roxo, com pontas brancas no inverno. Voo em bandos enormes (murmuração) é espetáculo notável. Excelente imitador. Omnívoro adaptável a ambientes urbanos e agrícolas.
Southern Cassowary
The southern cassowary is often called the most dangerous bird in the world due to its powerful legs and dagger-like inner claw that can reach 12 cm in length. Despite this reputation, cassowaries are vital rainforest keystone species, dispersing seeds of plants that no other animal can. The purpose of their distinctive casque remains debated.
