Birds are endothermic and maintain a constant body temperature through many of the same mechanisms that mammals use - restricting blood flow to extremities, rapidly twitching or contracting large muscle groups (shivering), puffing up their feathers and getting out of the wind/rain/snow.
They act like insulation just as any form of fur or covering does on animals (or like clothing for humans). Heat radiating out from the body hits the feathers and some of it is reflected back.
Some feathers (like ducks) also deflect moisture, keeping the inner body dry when in contact with water.
Warmth and water protection are done mostly by the small downy feathers tucked in close to the body. The longer more obvious feathers are more for flight stabilization and do little for warmth.
well they put there feathers around there head
40 to 44 oC
water proof feathers
They fluff up their feathers trapping air which is heated by body temperature. Sort of like a wetsuit it traps water and it warms up by the body temperature. Hope this helps
Birds are endothermic. Reptiles are ectothermic and are referred to as "cold-blooded."
they maintain body temperature by sleeping during the day and hunt at night
How do are body's maintain a constant temperature?
All mammals and Birds are warm blooded for example humans dogs seals etc
A black bear is endothermic, able to maintain its own body temperature. It is a mammal, and mammals and birds are endothermic. The term 'endothermic' is the biological term for an animal that is warm-blooded.
Sweat helps maintain your body temperature, Whenever your sweat evaporates, it cools you down.
by sleeping during the day and hunt at nightnoMajority of the cold-blooded animals maintain their body temperature by exposing their body to the sun
Maintain a normal value of certain body temperature.
No. A spider has no mechanism to maintain its body temperature.
