Melanerpes uropygialis
This desert-dwelling woodpecker is plain buffy-brown with black-and-white barring on the back. Adult males have a red crown. No similar species in range. Occurs singly or in pairs, often perched conspicuously atop a cactus. Comfortable in human settlements; frequently visits feeders and backyards in suburban areas. Primarily a Mexican species, occurring extensively across Baja and in the Pacific lowlands south to Jalisco. Limited range in the U.S., mainly in Arizona.

The back and wings of this bird are spotted and barred with a black and white zebra-like pattern. The neck, throat, belly and head are greyish-tan in color. The male has a small red cap on the top of the head. Females and juveniles are similar, but both lack the red cap of the adult male. White wing patches are prominent in flight. The dark tail has white bars on the central tail feathers. The birds range from 8–10 in (20–25 cm) in length.<p>This woodpecker's voice is a rolling churr sound. It also makes a yip yip yip sound and a kee-u, kee-u, kee-u sound. Its drum is long and steady.

行为
They build nests in holes made in saguaro cacti or mesquite trees. Cavities excavated by these woodpeckers in saguaro cacti (known as a "boot") are later used by a variety of other species, including the elf owl. There, they typically lay 3–4 white eggs, although as many as 6 or 7 have been noted. 2–3 broods are laid a year. Both sexes incubate and feed offspring.<p>As a woodpecker, its diet is composed greatly of insects, which it gains from drilling into bark. Gila woodpeckers are omnivorous, and do take fruits, nectar, seeds, as well as lizards, eggs, worms, and even young chicks of small birds. They are even known to hang on human placed hummingbird feeders and sip up the nectar.

其他鸟类
Chestnut-fronted Helmetshrike
Prionops scopifrons
A gregarious mostly dark-gray helmetshrike. Note the piercing orange eye, blue eye wattles, chestnut forehead patch, red legs, and orange bill. Small to medium-sized flocks inhabit coastal forest and lush woodland. Often in mixed flocks, most often with Retz’s Helmetshrike. Vocalizations include tearing notes, croaks, and bill snaps. Similar to Retz’s Helmetshrike, but easily separated by the chestnut forehead and blue rather than red eye wattles.
Greater Sand-Plover
Anarhynchus leschenaultii
Medium-sized plover with a long hefty bill. Breeding adults have a dark mask and orangish chest, neck, and forehead; females duller than males. Non-breeding birds and immatures are sandy brown above and white below, with a white throat and “eyebrows.” Often confused with Lesser Sand-Plover, and best distinguished when both present; look for larger size, heavier and longer bill, paler legs, and larger-headed appearance. Additionally, unlike some Lesser Sand-Plovers, Greater never has a black boundary around the throat. Breeds in high-elevation areas, where it favors arid, open habitats, sometimes near water. Winters on coastal mudflats and estuaries.
Wild Turkey
Meleagris gallopavo
Among the largest birds in North America. The large-bodied, long-legged and small-headed look of a turkey is distinctive. Appears dark from a distance. Often seen in small groups in open fields near woods. Gobbling often audible in the spring and early summer.
