It seems as though that as you look at smaller birds, their heart rate is higher than larger birds. This would lead you to believe that birds' hearts beat so fast because their small size. To keep up with it's surroundings, as well as simply to fly, the bird has to put out an immense amount of energy and oxygen. These is made up by the heart, which has to beat super fast to compensate.
