Willow Flycatcher (Empidonax traillii) at San Jose - August 2022

Featured Subspecies: Unknown

 NO UK STATUS IUCN Red List: Least Concern

The willow flycatcher is a widely distributed member of the infamous Empidonax genus, and is found throughout much of the continental USA. In the field, it is only clearly distinguishable from the Alder flycatcher by song, but that species isn't found regularly in California and most of it's breeding range is in Canada. This individual was seen when caught in mist nets by authorised handlers in San Jose, and was the only individual of the species we saw during the week.
