Empidonax traillii
The Willow Flycatcher is one of the infamous Empidonax flycatchers, a group so uniform that even museum specimens cause arguments. Brownish olive above and pale below with a weak eyering, it is best identified the honest way: by voice. Its sneezy FITZ-bew ends the debate instantly.
It migrates through Texas between wintering grounds in the tropics and brushy breeding territories across the northern United States. The endangered southwestern subspecies is a major conservation flagship along desert rivers.
This bird was photographed at Devine Lake Park in Leander during May migration, obligingly giving its sneezy fitz-bew from the willows.
