Wildfire shapes diversity of hermit warbler songs in California

New research shows that fire history seems to be shaping the diversity of bird songs throughout the state. The new paper, published in leading bird journal The Auk: Ornithological Advances, addresses the diversity of song dialects sung by hermit warblers – birds which get their name because they are rarely seen and spend much of their time in forest canopy. They are, however, very vocal and easily heard.
