What is a mountain canary?

The mountain canary, also known as the yellow-throated warbler (Setophaga dominica), is a small songbird found primarily in mountainous regions of North America. It is recognized for its bright yellow throat and distinctive song, which is often heard during the breeding season. These birds typically inhabit forests and are known for their agile flight and foraging behaviors, often searching for insects and other food in tree canopies. Their presence is an indicator of healthy forest ecosystems.
