	Willow Flycatcher (Empidonax traillii)
		Willow Flycatchers forage by either aerially gleaning (capturing an insect from a substrate while hovering) from trees, shrubs, and herbaceous vegetation or hawking larger insects by waiting on exposed forage perches and capturing insects in flight (Ettinger and King 1980, Sanders and Flett 1989).
		Willow Flycatchers have also been found in other riparian environments of various types and sizes ranging from small willow-surrounded lakes or ponds with a fringe of meadow or grassland to various willow-lined streams, grasslands, or boggy areas.
		Willow Flycatchers are known to breed at elevations from near sea level to 2440 m (8,000 feet) (Grinnell and Miller 1944, Zeiner et al.

		The southwestern willow flycatcher is restricted to riparian woodlands along streams and rivers with mature, dense stands of willows (Salix spp.), cottonwoods (Populus spp.) or smaller spring fed or boggy areas with willows or alders (Alnus spp.).
		Habitat interpretations for willow flycatchers are a function of the gender specific behavior of the birds observed and the scale of vegetation measurement (Sedgwick and Knopf 1992).
		The willow flycatcher population increases coincide with a dramatic decrease in cattle on the refuge and the elimination of willow cutting and spraying.

	PMA - The Willow Flycatcher in Alberta
		Grazing in willow or brushy habitat often removes the vegetation at the level which the Willow Flycatcher nests (Taylor and Littlefield 1986).
		Willow Flycatcher habitat in Alberta is usually too moist and the willows too dense to be accessible for grazing.
		The "cleaning" of willows and shrubs from lake edges could reduce available habitat but the greatest risk is lack of knowledge about the importance of the otherwise insignificant "waste" areas to this species.

	BFL: Species Account: (Southwest) Willow Flycatcher
		Overall, the Willow Flycatcher is a common and widespread species, with populations stable or increasing in the East, but declining in most western regions.
		Roughly the size of a small sparrow, the Willow Flycatcher is overall greenish or brownish gray above, with a white throat that contrasts with a pale olive breast.
		Note: As the Empidonax flycatchers are renowned as one of the most difficult groups of birds to distinguish by sight alone, the most reliable way to distinguish the Willow Flycatchers from other similar flycatcher species is not to rely upon its appearance, but rather through its distinct song.

	Southwestern Willow Flycatcher
		The southwestern willow flycatcher (Empidonax traillii extimus) is a small neotropical migratory bird that breeds in riparian habitats in the Southwestern U.S. and spends the non-breeding season in southern Mexico, Central America, and northern South America.
		While 55% of extant flycatcher sites are still dominated by native broadleaf plants, 33% of all flycatcher sites are comprised of mixtures of native broadleaf and exotic species, and 12% are comprised of pure stands of saltcedar.
		The ultimate need to ensure survival and recovery is to reduce habitat fragmentation so that dispersal patterns and capabilities of this subspecies result in a positive growth rate and population expansion, rather than the negative growth rates that characterize most of the small breeding groups that have been monitored.

	Southwestern Willow Flycatcher Recovery Involves the Public
		Each spring, the Southwestern willow flycatcher journeys thousands of perilous miles from Central and South America to breed in the few remaining dense riparian thickets bordering the Rio Grande, the Gila, the Colorado, and other rivers and streams in the arid Southwest.
		Because the issues associated with the Southwestern willow flycatcher’s endangered status are complex and were anticipated to be contentious, the Service appointed a team in 1998 to study the threats to the bird and to provide unbiased guidance for recovery of the species.
		The problem of riparian habitat loss— which adversely affects many species— is widespread throughout the Southwest as a result of urban and agricultural development, hydraulic modification such as dams, diversions and groundwater overdraft, fires, invasive plants, increased human population, and overgrazing by domestic livestock.
