I am a young ornithologist originally from PA but now living in central New York. I am pursuing a master's degree at Penn State University studying grassland birds and their relationships with different agricultural practices. When I am not working feverishly on my thesis, I enjoy adding new birds to my county, state and life lists, digiscoping and getting outdoors. I am active in the Pennsylvania birding community as chairman of the bird records committee, as well as a reviewer for sightings submitted to eBird. Some topics that really interest me are migration, bird distributions and vagrancy. Contact me if you have any questions about birds and birding in PA.
