Hummingbirds is typically high-strung. Their movements are unpredictable as they dodge from left to right without warning. They tend to stutter because of the fact that they think faster than they can talk. Them and chipmunks tend to not get along since the hummingbirds are convinced that they just hoard food. This notion is one of the reasons the Berry Battle started. But the chipmunks and hummingbirds are now on good terms.
