Human-modified environments, such as cities, are altering species interactions and increasingly leading to human-driven hybridization (Grabenstein and Taylor 2018). This hybridization in human-altered environments highlights the power of habitat disturbances to break well-established species barriers. However, few studies have experimentally assessed how disturbances drive hybridization. Combining genomics and field studies, I investigate how disturbance modifies interactions between chickadees to promote hybridization. My work focuses on establishing a long-term study, the Boulder Chickadee Study, as an experimental framework. I construct hundreds of nest boxes alongside numerous undergraduates and lab mates, affix these boxes to Ponderosas, Spruces, Firs & Aspen throughout Boulder backyards, and then monitor the chickadee families that move in. I enjoy connecting folks to birds in their own backyards by incorporating my chickadee research into as many outreach and mentorship opportunities throughout Boulder County as possible. In that vein, I am dedicated to increasing diversity and inclusion within STEM fields more broadly, as well as within the ornithology community, by actively mentoring fledgling female ornithologists, as well as folks from underrepresented groups.
