The desert finch (Rhodospiza obsoleta), sometimes called Lichtenstein's desert finch, is a large brown
It has an average wingspan of 26 centimetres (10 in). It has a stout black bill, black and white remiges and rectrices, and a slash of rosy-pink on each wing. The female is more dull in color than the male, but other than that the adult sexes are similar in color pattern.
The bird is indeed a desert resident in areas where water is readily available, but it can also be found in low mountains and foothills, and in cultivated valleys. It feeds on seeds and the occasional insect. Nesting occurs in trees in the spring, often in fruit trees in orchards, and the female lays and incubates 4 to 6 pale green, lightly speckled eggs.
This species does not migrate except locally. The desert finch congregates near rural and remote human settlements, and the well-watered orchard in otherwise arid land is an ideal habitat. It can be found in feeding in large flocks of its own species or mixed finch flocks.
Recent research by Zamora et al. (2006) has revealed that the desert finch is more closely related to the
Two subfossil greenfinches, the slender-billed greenfinch, Carduelis aurelioi, and the Trias greenfinch, Carduelis triasi, are known from the Canary Islands.
