Hummingbirds are the only birds in the world that can fly backward.
To balance out their average diet the hummingbird generally involves both nectar and small insects.
Most hummingbirds don’t like the cold weather.
That's why Most hummingbirds migrate to the tropics during winter, with those species found in the north heading south and those normally living south of the tropics heading north.
Hummingbird eggs can weigh as much as 10% of their mother’s body weight!
Hummingbirds have speedy metabolisms, which means that any food they eat gets processed and used up so quickly that they almost constantly need to eat.
That's why Hummingbirds hibernate at night, so they don’t starve.
