Hays Eagles Mom-Tongue study 2021 03 10 9:20AM

Eagles pant for several reasons, but most usually because they are hot. Birds do not sweat, so panting is a primary way of dissipating heat
The hole in the tongue is the “glottis” which is the entrance to the larynx and trachea which is known as the windpipe. The glottis closes during swallowing. The barbs are called “rear-directed papillae” and aid in the swallowing of food
