Lifelong naturalist and prospective graduate student, I am mostly active in the North American birding community as a records reviewer and columnist. I am particularly interested in evolution, hybridization, migration, and bioacoustics, and besides birds am relatively well-versed in plants and marine mollusks. I currently live in San Cristóbal de las Casas, Chiapas MX.
