LOL.. Obviously this is your first Terrier...
j.k, but seriously a lot of Terriers tend to do this! Our Airedale would stalk birds, squirrels, chipmunks, neighbourhood cats, and anything that resembled prey. It was more prevalent in our one female, who's prey drive was through the roof, but all of them did it to some extent.
I'm sure that some of the pointing/setter breeds may do this behavior as would the herding breeds and the sighthounds. Just Terriers seem to still have such a strong prey drive.
