Members of the Taylor lab are busy in the field these days, braving the cold and snow to collect exciting data on black-capped and mountain chickadees. Haley is conducting feeder-based agression experiments in Boulder, Nikki has been getting our nest boxes ready for the 2024 breeding season, and聽Sara, Ajay, Will, 聽Scott, and Haley have been banding chickadees at the Mountain Research Station with PIT tags (see yellow band on mountain chickadee above) for聽upcoming experiments on spatial cognition. Along the way we've enjoyed visits from an American pine marten (a lifer mammal for Will, Sara, Ajay, and Scott) and pine grosbeaks!
