John Yerger has been birding since he was 8 years old.  His interest in birds developed into more of an obsession by high school, and led him to pursue a degree in Wildlife and Fisheries Science at Penn State University.  Along the way he participated in many research projects, on topics ranging from Painted Redstart foraging ecology in the Chiricahua Mountains to Tree Swallow behavior at Cornell University.  While John enjoys every bird from the drabbest common sparrow to the brightest rare warbler, he is equally engaged by many other aspects of natural history.  John has led trips from the boreal forests of Canada to the subtropics of Mexico, but primarily enjoys living and birding in southeastern Arizona with his wife Morgan and their dog Madison (an Australian shepherd mix).

John is a full-time tour leader for the Adventure Birding Company based from his home in Portal, AZ.  He also serves as a Board Member for the Arizona Field Ornithologists and the Friends of Cave Creek Canyon, is a member of the Arizona Bird Committee, and volunteers with the Tucson Audubon Society.

Most recent adventure: traveling the full length of Argentina for 2.5 months with fellow guide Jake Mohlmann, tallying more than half of the country's roughly 1000 species (and polishing his Spanish language skills).

Upcoming trips with John:
