The smallest living bird, the Bee Hummingbird, weighs a mere 2 grams.
The male hummingbird is more colorful than the female. But the female birds are larger in size.
The heart rate of a hummingbird can vary from 250 to 1,200 beats per minute. But at night, during torpor, it can lower this from 50 to 180 beats per minute.
The maximum flight speed of a hummingbird is 30 miles per hour. But it can reach speeds up to 60 miles per hour during a dive.
Interestingly, the hummingbird flies upright, unlike other birds who fly flat.
The hummingbird can see and hear better than humans, but their sense of smell is non existent. Their taste buds are not that great either. They can only make out what is sweet and what is not.
They are able to see ultraviolet lights.
To satisfy its tremendous hunger, the hummingbird may visit up to a thousand flowers every day.
While it is feeding, this bird can lick up to 15 times per second.
These little birds are very territorial by nature. They can be quite aggressive with other males, or even insects if need be.
Although the hummingbird is the smallest in size, its brain is 4.2% of its body weight, making it the largest proportion among all birds.
The metabolism of this small bird is around a hundred times that of an elephant.
These birds are quite lonesome. They live or migrate alone. In fact, the only time they bond is while reproduction.
The hummingbird has a good memory. They remember all the flowers and places that they have visited, so much so that they return to it the next year too.
Most hummingbirds die in the first year of birth, but overall their average lifespan is 5 years, with the maximum being 12 years.
The hummingbird is probably the only bird whose predator is an insect. Praying mantis feed on them.
