One of the most important characteristics that birds share with mammals are that both are warm-blooded, which means that they regulate their own body temperature. Both birds and mammals also typically care for their young until the young can care for themselves.
They are all vertebrates: Females have two lateral vaginas, which lead to separate uteruses. A third canal, the median vagina, is used for birth. Males have a two-pronged penis, which corresponds to the females' two vaginas. The penis is used only for discharging semen into females, and is separate from the urinary tract. Birds have unique modified immune system that fights off bacteria found in seeds and plants.

Analogous Features.
Birds are grouped based on the shape of two features. These features are their beaks or bills, and their feet. Feathers are sometimes taken in to account as well.
Similar features in organisms that do not share ancestry means both organisms adapted to their environment. They developed the features to survive.
Feathers
Penguins have feathers, wings and a beak. Penguins lay eggs and feed their babies.
Marsupials are mammals, so share all features with other mammals. As well, they are vertebrates, so share the characteristic of having a backbone with birds, fish, reptiles and amphibians. Like birds and reptiles, mammals breathe via lungs (rather than gills), and like birds, they are warm-blooded.
