How Many Types of Birds are out There?

There are a lot of types of birds! There are about 9,700 types of birds! I'll list all of the types I can recall: cockatiels, green cheek conures (my favorite type of bird), conures, flamingos, penguins, parakeets (I have two of them as pets at home, they're really fun to play with!), pigeons, robins, red robins, blue jays, parrots, seagulls, ducks, and crows
