Common Yellowthroat Warbler in Quaking Aspen
The Common Yellowthroat (Geothlypis trichas) is one of the most widespread and numerous warblers in North America. It is known for its distinctive call, and the black ‘outlaw’ mask of adult males that is so visible here. These birds prefer habitat full of dense vegetation, and are often found in wetland thickets where they are well protected as they glean for insects on the ground. This yellowthroat is perched on quaking aspen (Populus tremuloides), a tree with a vast native range in North America— from Alaska to mountaintops of the west, and throughout the northeast. It is a fast-growing, early succession tree that prefers a cool climate and thrives after disturbances like wildfires. It is also an ecological powerhouse, supporting the larvae of nearly 100 species of moths.
