Willow Flycatcher Nesting �The Willow Flycatcher breeds in "moist brushy thickets, open second-growth, and riparian woodland, especially with willow and buttonbush.
Willow Flycatcher Nesting �Two newly discovered populations documented in the Cascades during the past two years almost double the known population of this subspecies in California.
Willow Flycatcher Feeding �Willow Flycatchers forage by either aerially gleaning from trees, shrubs, and herbaceous vegetation or hawking larger insects by waiting on exposed forage perches and capturing insects in flight.
Willow Flycatcher Feeding �A local, concentrated source of nutrients in the form of flying insects is required to meet the nutritional needs of territorial establishment and defense, mating, nest building, egg laying, brooding, and nestling rearing.
Willow Flycatcher Endangerment �This species has declined because of removing, thinning, or destroying riparian vegetation; water diversions and groundwater pumping which alter riparian vegetation; overstocking or other mismanagement of livestock; and recreational development.
Willow Flycatcher Endangerment �One of the first imperiled animals the Center championed, the southwestern willow flycatcher has suffered more than a century of steady decline.
Willow Flycatcher Endangered �Simultaneously, we’re defending flycatcher habitat along Arizona’s San Pedro River from unsustainable groundwater pumping, offroad vehicle destruction and other ecosystem threats.
Juvenile Willow Flycatcher �The Little Willow Flycatcher, or Pacific slope subspecies of the willow flycatcher, breeds in California from Tulare County north, along the western side of the Sierra Nevada and Cascades, extending to the coast in northern California. �
What can we do to help them recover? �Recovery Plans delineate reasonable actions that are believed to be required to recover and/or protect listed species. � Plans are published by the U. S.
Willow Flycatcher Recovery �They represent the official position of the U. S. Fish and �Wildlife Service only after they have been signed by the Regional Director or Director as approved.
Fun facts about the Willow Flycatcher �Length: 5. 75 inches Weight: 0. 42 oz Wingspan: 8. 5 inches �This subspecies has a grayish-green back and wings, whitish throat, light gray-olive breast, and pale yellowish belly
Fun facts about the Willow Flycatcher �Between August and September, the southwestern willow flycatcher migrates to wintering grounds in Mexico, Central America, and possibly northern South America. �The southwestern willow flycatcher breeds in relatively dense riparian tree and shrub communities associated with rivers, swamps, and other wetlands including lakes and reservoirs.
