Ornithology writer and naturalist studying ecology & evolutionary biology. My main interests and areas of expertise include birds, plants, and marine mollusks, but I try to let all aspects of the natural world capture my interest. My professional experience includes field work studying genetically and vocally distinct populations of Red Crossbill (Loxia curvirostra) and multiple seasons conducting breeding bird and vegetation surveys in the Rocky Mountains and northern Great Plains. I consider my strongest niche in ornithology to be in bioacoustics, and I record any new or interesting bird vocalizations I encounter in the field, with a special fascination of flight calls.
