Desert Finch

Overview

The Rhodospiza obsoleta, also known as Lichtenstein's desert finch, is a large brown true finch native to southern Eurasia. Despite its classification, genetic research indicates it is more closely related to the greenfinches of the genus Chloris than to other traditional finches.

Identification

• Average wingspan of 26 centimetres.
• Stout black bill with a distinct slash of rosy-pink on each wing.
• Black and white remiges and rectrices.
• Females appear duller in colour than males, though both share the same colour pattern.

Habitat

Found in deserts where water is readily available, as well as in low mountains, foothills, and cultivated valleys. It frequently congregates near human settlements, with well-watered orchards in arid lands serving as ideal habitats.

Diet

Feeds primarily on seeds and the occasional insect, often seen in large flocks of its own species or mixed finch groups. Nesting occurs in trees, particularly fruit trees in orchards, during the spring.

Did you know?

Molecular studies suggest that greenfinches may have evolved from a desert form, or that both lineages diverged from a common ancestor living in semiarid habitats around six million years ago.
