2 - Aerial Acrobatics, Hummingbirds
Not only are hummingbirds among the most beautiful birds on the planet, they are also the most impressive flyers. Within their wings the joint between the upper and lower arm is positioned very close to the body, giving them incredible leverage and flexibility in the air. They also beat their wings extremely fast - some species at 80 times per second, and do so in a figure eight pattern, which adds to their maneuverability. Hummingbirds are the only birds that can fly backwards and upside down. They are also the only bird with the ability to hover in the air, which is both captivating to look at and extremely advantageous for feeding on plant nectar.
