The western yellow-billed cuckoo uses river corridors as routes to travel between its wintering and breeding grounds. Nesting pairs find refuge in willows, cottonwood, and other trees along waterways, and play an important role in the health of river systems throughout their range.
Threats to this rare songbird's habitat include altered hydrology, grazing, non-native vegetation, human disturbance, and climate change.
