Say’s Phoebes live in dry, sparsely vegetated areas including, sagebrush flats, badlands, dry barren foothills, canyons, and borders of deserts up to about 9,300 feet. They often gravitate to buildings like other phoebes, but unlike their cousins, Say's Phoebe's avoid heavily forested areas and watercourses. During the winter Say’s Phoebes also use open, grassy fields with scattered shrubs and agricultural areas. Back to top
This phoebe's diet consists almost entirely of insects such as beetles, grasshoppers, crickets, flies, and bees. They sally from low perches to snatch insects in midair or pounce on insects on the ground.Back to top
The pair investigates potential nest sites together. They look for a protected ledge or pocket in caves, cliff faces, dirt banks, bridges, barns, and other buildings. The most important feature is shelter from above. Nest height is extremely variable and depends on the height of the structure.
Female Say’s Phoebes build cup-shaped nests on natural or human-made ledges that have shelter over them. Females use rocks, plant stems, sage, wood, grasses, and spiderwebs to form the base of the nest. They line the nest with hair, wool, paper, or feathers. Nests are about 6 inches wide and 7 inches long with an inner cup about 4 inches in diameter. Females sometimes reuse nests from the previous season or use nests built by other species. If they reuse a nest they add a fresh lining of feathers and hair to the old nests.

Say’s Phoebes tend to perch on low shrubs or even grasses from which they sally out to grab flying insects. They often wag or pump their tails when perched, although they do this less often than either Eastern or Black phoebes. Their flight is direct, buoyant, and graceful. They form pair bonds early in the spring, although it is unclear if pairs stay together for multiple years. Males escort females around to potential nest sites. He flutters his wings while chattering to the female until she selects a spot to build a nest. One or both phoebes often return to the same territory year after year, sometimes even reusing nests from the previous year, but it’s not clear if it is with the same mate. During the nonbreeding season, phoebes are mostly solitary. Back to top
The Say’s Phoebe is common throughout arid regions of the West. Populations showed a small increase between 1966 and 2015, according to the North American Breeding Bird Survey. Partners in Flight estimates the global breeding population size at 4 million individuals, with 85% spending at least part of the year in the U.S., 62% in Mexico, and 6% breeding in Canada. The species rates a 9 out of 20 on the Continental Concern Score and is not on The State of North America’s Birds 2016 Watch List. Say’s Phoebes may benefit from increases in human-made structures in arid regions, as many of these buildings provide places for them to build their nests.Back to top
Say’s Phoebes don’t come to feeders, but they may use your backyard as a place to catch insects or even build a nest under the eaves of your house or other structure in your yard.
A well-placed shelf attached to a building may attract a pair. Make sure you put it up well before breeding season. Find out more about nest shelves and how to build one at NestWatch. You'll find plans for building nest structures of the appropriate size for a Say's Phoebe on All About Birdhouses.
Create bird friendly habitat in your yard by planting native shrubs. Creating habitat in your yard can provide foraging opportunities for the Say’s Phoebe.Back to top
