Willow flycatchers, already an endangered species, also imperiled by climate change

May 15, 2018

The southwestern willow flycatcher is facing serious environmental challenges.

When the migratory songbird was added to the endangered species list in 1995, it was mainly because of habitat loss caused by human development. It also gets bullied by another bird species, the brown-headed cowbird, which destroys its eggs and steals nests.

Now, according to a UCLA-led study, the willow flycatcher is facing another threat: climate change.
