Habitat & Range

The Willow Flycatcher breeds in much of the western and northern U.S, and winters along the east and west coasts of Central America. Unique to the Great Basin Willow Flycatcher is their specialized habitat preference. They are commonly found in dense riparian areas with willows and other shrubs in the Great Basin region.

  • Grasslands
  • Upland Forests
  • Warm desert riparian

Threats

  • Drought
  • Habitat Loss
  • Overgrazing

Great Basin Willow Flycatchers are typically monogamous, though there are occasional instances of polygyny, where a male may mate with more than one female. In such cases, polygynous males divide their time between their mates.

The breeding pair lays 3 to 5 creamy white eggs with irregular brownish spots and blotches. The female incubates the eggs for about 12 to 15 days. After hatching, the nestlings remain in the nest for 13 to 16 days, followed by the fledgling stage. By around two weeks of age, fledglings can fly short distances but stay close to the nest for an additional three to four days. Juveniles typically leave their natal territories 14 to 25 days after hatching.

Great Basin Willow Flycatchers feed primarily on insects, which they catch in midair or pick from leaves while hovering. Their diet includes bees, wasps, ants, beetles, damselflies, butterflies, moths, and flies. In the fall, they occasionally consume berries such as blackberries, raspberries, currants, and dogwood berries.

Fun Facts

Unlike many birds that learn their songs from their parents, Willow Flycatchers are born with their songs already programmed. Scientists have found that even when raised in captivity and exposed only to the song of a different species they will still grow up singing their species' distinctive "fitz-bew" song.
