Transcript of Birds
All birds have feathers and wings
They don't have teeth
Can maintain a high energy level because they are endotherms- animals that can maintain a constant body temperature not depending on the outside temperature
Have clawed tows and protein scales on their feet
All birds have beaks and/or bills
Can live in all environments Long wings for soaring on updrafts
Short wings for short quick flights
Beaks depend on the environment they live in
Feathers keep them cool and give them camouflage abilities
Feat adapted to swimming, perching, walking or catching prey Most birds do not have external sex organs. The transfer of sperm from male to female usually takes place while the male bird is standing or treading on the female’s back. The male twists his tail under that of the female so that the opening of the male bird’s cloaca, or waste storage chamber, is close to that of the female’s.
