Sterlings are copycats. This bird can baa like a sheep, bark like dogs and scream like children. They can also tweet like a whistle, which confuses sport players. They do not have the best singing voice in the bird world by far, but you can't blame them for trying. They copy other birds as much as they are able to. No two sing the same song, they all aur original.
The best at singing is the best at mating, maybe because they are most likely to protect their hatchling, to scare away predators. Each season the males add more sounds to their songs. They nest everywhere from skyscrapers to woodpecker holes and birdhouses.
