No. Birds and mammals have radically different lung designs. Birds have a far more complex, but more efficient design than mammals do.
Emus are not mammals, and are therefore not the same as other mammals at all. Emus are birds.
No. Peacocks are birds. Giraffes are not birds, they are mammals.
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.
No, Owls are birds, Bats are mammals.

No. Bats are mammals while birds are descended from dinosaurs.
No. Mammals and birds are both vertebrates, particularly amniotes, but beyond this they are not relate to each other. They share a number of characteristics including:Warm bloodednessA high metabolic rateA four-Chambered heartA soft covering over their skincaring for their young.But Mammals and birds developed these traits separately.
The same way birds do.
Think of it as the same thing as land mammals versus water mammals. Marine mammals first evolved to life on land and then adapted to return to the water, but not all mammals did that. Similar thing with birds. All birds evolved from common flying ancestors, whereas flying mammals evolved from land mammals at a much later point in evolutionary history. Hope that helps.
No, they are not the same, but all reptiles are vertebrates. Not all vertebrates are reptiles, they could be fish, mammals or birds.
No, birds belong to the class Aves: warm blooded, bipetal, lay egging, vertebrates. Mammals have mammiliary glands (breast milk), sweat glands, and have hair.
Amphibians are in the same kingdom as mammals, birds, reptiles, fish, and insects, the Animal Kingdom.
