Are Penguins a bird or mammal?

George S asks:

I’m having an argument with this noob at work – his name’s Tom L. He thinks that penguins are birds. Just wanted to confirm before I call him out on it.

Penguins are birds for the following reasons:

Some penguins have fur – but only those who can afford it.I don’t know the answer but that Tom does sound like a noob.
