birds and mammal are alike is because birds lay eggs and mammals have a alive birth and also that mammals have teeth and birds have bills
Those are differences.
Both birds and mammals :
- are warm blooded.
- have bones
- have feet / legs
- breathe air - have lungs
- have a nervous system
-some mammals lay eggs - echidna and platypus
Blood ?
Bones?
Lives ?
any of these make an importance to you ? :
Both warmblooded and vertebrates!
they lay eggs.
They are not THAT closely related; bats are mammals, not birds. Both mammals and birds are vertebrate animals.
birds have eggs and mammals have living babies
They are both warm-blooded vertebrates that care for their young.
Apart from both being animals, they are both warm blooded.
mammals,birds,reptiles and amphibians.Any animal with its skeleton inside it.
Both birds and mammals care for their young.
Birds and mammals both evolved from reptiles.
Mammals and birds are both vertebrates descended from an early reptilian ancestor.

No. Birds and mammals are separate classes each containing hundreds of genera. Their closest connection is that both birds and mammals are amniotes, a group that also includes reptiles.
Bats are mammals. Owls are birds.
yes
Mammals have fur, and birds have feathersMost mammals give birth to living young and birds lay eggs
They are not THAT closely related; bats are mammals, not birds. Both mammals and birds are vertebrate animals.
Mammals and birds are both descended from a group of vertebrates known as archosaurs. This group included early reptiles and gave rise to both dinosaurs (which birds evolved from) and the ancestors of mammals.
Adaptations that birds and mammals share include the fact that they are both warm blooded, they are both vertebrates, and they both have four chambered hearts. Unlike mammals, birds are covered in feathers and all birds lay eggs. Unlike birds, mammals are covered in hair, produce milk for their young, and nearly all mammals give birth to live young (except a few species that lay eggs).
Of course not ...no birds are mammals !!!!!!!!!!!No, they are birds.
