Hummingbirds are the only birds that can fly in different directions. They can hover forward, backward, sideways, in mid-air, and even upside-down!
Hummingbirds have a very fast metabolism, which is nearly 100 times faster than that of an elephant.
Female hummingbirds only lay two eggs and are responsible to build the nest. The young hummingbirds will stay in the nest for about 3 weeks.
Even though hummingbirds are the smallest birds in the world, their migrations can span hundreds or thousands of miles. While there are more than 300 hummingbird species, only a handful of them regularly migrate.
Don’t judge them by their size as hummingbirds have speed and stamina. They have been clocked in direct flights at about 30 mph and in courtship dives at 45 mph.
When hummingbirds sleep, they go into a hibernation-like state called Torpor (pronounces TOR-per). Their metabolism will lower to one-fifteenth (1/15) of normal. Their body temperature will drop to the point of becoming hypothermic.
Hummingbirds do not fly as a flock but rather individually during migration. They also compete for their food sources. But the mating season is the most interesting as these cute little birds turn into feisty fighters.
