Blue Jays are especially good at mimicking a specific group of birds. Which birds do they imitate most?
While Blue Jays mimic many sounds, the birds they imitate the most are hawks. They have been observed making "hawk calls" as a warning that hawks are nearby, but they have also been observed using "hawk calls" to scare other birds from a food source, letting the Blue Jay get the food instead. The Blue Jays in our yard seem to do it to see how many times I will grab the camera, hoping to photograph a hawk.
