Straw-necked Ibis

Threskiornis spinicollis

Also known as: Australian Straw-necked Ibis

The Straw-necked Ibis (*Threskiornis spinicollis*) is a large Australian wading bird recognised by its dark glossy body, long downcurved bill, and the pale straw-like feathers that appear around the neck during the breeding season. It frequents wetlands, flooded grasslands, and agricultural areas, where it feeds on insects, frogs, crustaceans, and other small prey while probing in mud or short vegetation.

Did you know?
Straw-necked Ibises often gather in large flocks after rain, taking advantage of newly flooded ground rich in insects and other prey.
