Prospective grad student, birder since early childhood, member of the Colorado Bird Records Committee, columnist in the Colorado Birds journal authoring "Field Marks". I am particularly interested in evolution, hybridization, migration, and bioacoustics, and besides birds am relatively well-versed in plants and marine mollusks.

Multilingual including Spanish and French. Feel free to reach out: davidtonnessenx@gmail.com
