Today is a tribute to the hummingbird. I made a mini hummingbird...it's about the size of a nickel.
I found a bunch of neat facts about hummingbirds. Our new show features a hummingbird, so we wanted to know as much as possible.
- Hummingbirds are the tiniest birds in the world, but their brain weight (4.2% of its body weight) makes it the biggest birdbrain!
- A hummingbird's brain is 4.2% of its body weight, the largest proportion in the bird kingdom.
- Hummingbirds are can remember every flower they have been to, and they know how long it will take each flower to refill.
- Hummingbirds can hear better and see farther than humans -- they can even see ultraviolet light! They do not have a sense of smell.
- A hummingbird's tongue is grooved like the shape of a "W" with tiny hairs on the tip to help lap up nectar.
- A hummingbird's heart beats up to 1,260 times per minute; the heart beats 250 times per minute at rest.
- A hummingbird's metabolism is roughly 100 times that of an elephant.
- An average sized hummingbird will have about 940 feathers.
- Females will lay a clutch of two eggs; the babies are about the size of a penny.
- Hummingbirds can fly both forward and backwards; they can hover, fly sideways and even upside-down! A hummingbird wings will beat about 70 times per second. Hummingbird's wings will beat up to 200 times per second when diving.
- Ruby-throated hummingbirds have been known to travel 500 miles over the Gulf of Mexico to breeding grounds. This trip takes about twenty hours.
- Hummingbirds need to eat on average 7 times per hour for about 30-60 seconds; they will visit an average of one thousand flowers per day for nectar. Many plants depend on hummingbirds for pollination.
