There are 6000 to 7500 gray wolves in the US lower 48 states (and nearly 10000 in Alaska.)

The Eastern Coyote is larger than the western variety and has some wolf DNA. It seems to be evolving to fill the niche the wolf occupied in the eastern US. There may be as many as 4.7 million coyotes in the US. There's a pair in Central Park in New York City; Chicago has ~2000.
