Emus and cassowaries are two of the very few birds that can't actually fly at all. They are related to a group of birds called ratites. Other ratites include the ostrich from Africa and the rhea from South America. Ratites have wings but the bones in their chests do not have the capacity for flight muscles, which is what a bird needs to fly. Although the emu does not actually weigh as much as it appears (30-45kg), its wings are also too small by comparison to lift it. The cassowary is heavier than the emu, and its wings are also too small to enable it to fly.
Maybe it's because there wings are to small for there body.
Kangaroos cant fly because they have no wings, which are the most parts of any flying creature that helps them to fly. So because they have no prerequisite like wings they can not fly.
No, a penguin is not a mammal. A penguin is a bird. However, it is one of the few birds (like the ostrich) that does not fly.

Hare. A hare is much like a large rabbit. The rest are fouls (edible birds)
Ostrich
Yes, a penguin is flightless. Similar to other flightless birds like the ostrich, they lack proper flying anatomy. They have flippers that allow them to swim instead.
yes, a ostrich is because it is a non-flying bird and it's fat just like the dodo birds, but the dodo birds were killed by men not ostrich's.

The ostrich is a bird. It lays eggs, like all birds. It is not a member of the mammal family.
