Congrats to Kathryn and her co-authors for their recent pulbication in Ecology and Evolution . Kathryn reports an interesting pattern of reduced body condition in black-capped and mountain chickadees that co-occur and discusses potential drivers (e.g., crytpic hybridization, range edge effects,聽competition). Stay tuned for more from Kathryn in the coming months as her other thesis chapters are published. Congrats Kathryn!
