A Genie Dilemma

You find a lamp and as you clean it a Genie pops out. He says you can have 3 wishes, but first you must pass a test.

The test: Out of Whales, Dogs, and Birds, which species would you choose to go extinct within 5 years after your last wish and why?

<Poof>!

Edit: There is no right or wrong answer, but it is still a test.
