The answer to that question is no, and a cockatoo is not bigger than a macaw. Cockatoos are a parrot species, and most look pretty similar. Macaws, on the other hand, belong to a different family entirely. Hence, they're large parrots native to South America. The average cockatoo weighs around 800 grams (1.7 pounds), while macaws reach almost 2 kilos (4 pounds). So, when it comes to mass and size, they're very different creatures. Additionally, there's another distinction between these two bird families: their plumage! Above all, they are also on our list of the biggest parrots.
