Regulation of Heat Exchange across the Hornbill Beak: Functional Similarities with Toucans?
Beaks are increasingly recognised as important contributors to avian thermoregulation. Several studies supporting Allen's rule demonstrate how beak size is under strong selection related to latitude and/or air temperature (Ta). Moreover, active regulation of heat transfer from the beak has rece...
