They enjoy a diet of insects and spiders. The bird is brown-gray in color, which mimics its habitat, and features a pale eye-stripe. It's about 15 cm in size.

House Finch
The house finch is a common bird not just in myriad habitats around Maricopa County, but throughout North America as well. In the Sonoran desert, they can be found on mountain slopes and along washes. They enjoy a diet of seed and consequently often are seen in Phoenix, where they are attracted to bird feeders. However, they are vulnerable to infectious diseases that can be transmitted through bird feeders and bird baths. Bird lovers should make sure their bird baths and feeders are kept well cleaned.
Curved-Bill Thrasher
The curved-bill thrasher is a desert songbird well renowned for its "singing voice." It thrives on a diet of insects, grubs and small lizards, which it catches with its heavy, curved beak. This thrasher also will dine on fruit, including wolfberries and saguaros. It is noted for its distinctive yellow eyes.
Black-throated Sparrow
The little black-throated sparrow also is noted for its beautiful singing. It is common throughout the southwestern United States. Its characteristics are distinguished by a jet-black throat and two contrasting white facial stripes along with a conical beak that is ideal for seed cracking. They are common visitors to bird feeders. However, once it has a nest full of baby birds to feed, it will begin to gather insects.
Verdin

They are pale gray in color with a bit of yellow on the face and dark red on the shoulder, and sport a fine-point bill.
