Monarch butterflies migrate every winter by flying more than 2500 miles, from Canada's side of Lake Huron, all the way down to Mexico. How they navigate is still an unsolved mystery.
The Bee Hummingbird (Mellisuga helenae) weighs approximately 1.8 grams, less than a U.S. penny. It is the smallest bird in the world, measuring just 2.2 inches long.
The largest bird nest in North America is built by the American Bald Eagle. Their nests can be up to 14 feet deep and 8 feet wide.
The highest flying bird in the world is the Ruppell's Griffon vulture. It has been spotted flying at 37,000 feet, an altitude that only the most sophisticated jet planes can reach.
The Arctic's Woolly Bear Caterpillar freezes solid every winter for 14 years, until it has consumed enough food to form a cocoon and turn into a moth. It has the longest life of all butterflies and moths.
Hummingbirds do everything fast. In just one minute they can flap their wings 50 times, have their heart beat 1200 times, and take 250 breaths of air.
