Recent discoveries suggest that the earliest birds descended from a small dinosaur known as Archaeopteryx, which developed feathers. Possibly to keep warm.
Birds all have feathers, and their young (as the dinosaurs before them) hatch from eggs. The flying birds have hollow bones to reduce weight, but most ground -dwelling Flightless Birds have more conventional bones. Birds mostly care for their hatchlings, apart from exceptions such as the Cuckoo family.
In general the flightless birds such as Kiwi, Ostrich Emu, etc lack a keel bone in their chest to which flight muscles would otherwise attach. This family probably never had flight, but that is subject of dispute.
