They usually hang upside-down the tree during this phase. Heart rate slows down, temperature drops and their metabolic rate decreases to 1/15 of the normal rate. When resting, heart rate reaches 250 beats per minute.Įach night hummingbirds enter hibernation-like state called torpor which helps them preserve the energy. Average heart rate during the flight is 1200 beats per minute. Hummingbird has incredible high heart rate. Hummingbirds also eat insects, which provide them with enough proteins. Hummingbird usually visits 1000 flowers per day. Nectar from flowers is the best source of sugar and hummingbirds drink it 5 to 8 times each hour. Hummingbirds use carbohydrates (sugars) as the main source of energy for flight. This type of flying requires a lot of energy and that is the reason why hummingbirds eat a lot of food each day.

They have larger brain size (compared to the rest of the body) than other birds. Hummingbirds are very intelligent animals.

This unique characteristic is the result of the iridescence coloring of the feathers and the influence of light, moisture and other factors. Hummingbirds have lower number of feathers compared to other birds (less than 1000), but they are known as "the flying jewels" because they are able to change the color of their feathers when they fly. Most hummingbirds reach 3.3 inches in length and weigh between 0.07 and 0.7 ounces. Global warming (climate changes) affects their migratory patterns and changes the normal behavior of hummingbirds. Destruction and loss of habitat affect the number of hummingbirds in the wild. There are 343 different hummingbird species that can be found in the North and South America.
