bats are birds because they fly and look like birds. that's how we define things: by looking at them.
ostriches are birds because they look like birds. flight is not necessary, if they are enough similar to a bird.
i wouldn't call penguins birds because they look kinda weird. a little birdish, but not entirely birds. they are waterbirds.
i think it's foolish to say that an animal is a different kind of animal just because it is warmblooded or coldblooded, or if it lays eggs instead of children, because a normal person can't even notice if a creature has warm blood or not, only scientists can do that, so scientists can have their definitions and we normal people have our own
