Question

PLEASE HELP: Which of the following specialized structures help a bird maintain a constant body temperature?

A. Hard beaks

B. Edoskelteons

C. Watertight eggs

D. Feathers

Answer 1

D. Feathers

Step-by-step explanation:

The feathers help the bird hold and maintain a constant body temperature. When they fluff up their feathers it allows air to get inside and heat them up. (I would know I have a pet parrot myself) I hope this helps.
