Black-capped and Carolina Chickadees
What we study:
Black-capped and Carolina chickadees hybridize in a long and narrow zone of contact that extends from New Jersey to Kansas. Our research on this hybrid zone has used genomic and community science data to document the speed at which it is moving northwards and found that this movement is tightly linked to warming minimum winter temperatures. We’re continuing our work on this hybrid zone by investigating what causes hybrids between these two species to have poorer spatial cognition and problem solving abilities than either parent species (NSF IOS ) and by studying the genomic basis of physiological adaptations and their breakdown in hybrid chickadees (NSF DEB ).
