An interesting fact for kids is that hummingbirds have evolved tiny feet to improve their flying abilities. Because of this, they are not able to hop or walk. Instead, they move from side to side when perched. Roughly one-third of the hummingbird's weight comes from muscles that are used for flying.
Depending on various factors, including wind and direction of travel, hummingbirds can flap their wings between 50 and 200 times in just one second. Their hearts beat more than 1,200 times every minute. When they are not flying ,hummingbirds take approximately 250 breaths every minute.
Because they must ingest around 50 percent of their body weight every day, hummingbirds feed on nectar between five and eight times every hour. They are capable of using their forked tongues to take between 10 and 15 licks of nectar in one second. Hummingbirds have excellent vision, but they do not have a sense of smell at all.
Out of all of the birds in the world, hummingbirds have the least amount of feathers, usually between 1,000 and 1,500. Mother hummingbirds lay eggs that are around 0.5 inches long, making them the smallest bird eggs in existence. Depending on factors such as location, predators and species, hummingbirds usually live to be between 3 and 12 years old.
