Willow Flycatcher

Empidonax traillii

Formerly lumped with the Alder Flycatcher as the Traill’s Flycatcher, the Willow Flycatcher has been given full species status. The split occurred in 1973. While the Alder Flycatcher breeds mostly in Canada, the Willow chooses more southern latitudes. The northern limit to their range is south-western Canada. Except for the south-eastern USA, this bird will breed throughout most of the USA. Winter will find these birds in Central America and Colombia. They may live as long as eleven years.

The “Southwest Willow Flycatcher” (Empidonax traillii extimus) was listed as endangered in 1995. Habitat loss and cowbird parasitism are listed as root causes of their decline.
