Title: Advances in chickadee hybridization: birds and methods on the move
Description: Hybridization between Black-capped and Carolina Chickadees has been a research focus in several laboratories for more than a decade. Our field studies in southeastern Pennsylvania, along with new Breeding Bird Atlas results, have documented rapid northward movement of the hybrid zone. Our current work considers whether differences in personality between and within the species influence hybrid zone dynamics. This research incorporates powerful new field methods to investigate behavioral variation on multiple levels.
Regards,
Phil Witmer
