A toco toucan at @theomahazoo. This toucan’s beak is the largest of any bird’s relative to body size and contributes to 30-50% of the toucan’s entire length. This bird’s beak serves many functions including peeling and picking fruit, territorial displays of defense, sexual selection and even body temperature regulation. Research has shown that instead of sweating when they get hot, toucans send a rush of blood into their beaks and allow the heat produced there to radiate out of their bodies and into the air. When these birds get chilly, they can restrict the amount of blood sent to their beaks and retain that heat to stay warm. #tocotoucan #photoark #savetogether #birdsofinstagram
