Life history

How this bird lives

Habitat and nesting

Females weave plant strips around supporting stems to form a secure nest. Outside breeding season, birds often gather in large mixed flocks. [2]

Food and foraging

Insects in summer; seeds and grain in winter. [2]

Watch where the bird searches for food and how it moves. Feeding behavior can be a useful clue alongside plumage.
