I think the person writing the subheadline for this AP story carried by MSNBC either failed his biology or he's a complete buffoon. Penguins are not mammals, you dumbass! They are birds! And it's apparent that he's not too good with his spelling too. Babes? What babes? Babies, you mean.
Update: I guess someone in MSNBC doesn't like me calling their editor a buffoon so they have corrected the error. It's now birds! (Thanks Shy, GeekGod)
