Almost every part of the hummingbird’s life is shaped by their dependence on flowering plants. This includes their size, shape, their ability to hover in flight, their mating habits, and migration. The nectar that is found in flowers that has been pollinated by hummingbirds is very rich in sugars, especially sucrose, which is commonly found in sugar cane and sugar beets.The hummingbirds depend on these sources because of their high metabolic rates which are necessary for them to achieve hovering flight. The small body size of the hummingbird that helps them to achieve optimum flight performance, but it also results in a higher rate of heat loss. The hummingbird must take in an enormous about of calories to help ensure their ability to maintain a normal body temperature.

Probably the easiest way to attract hummingbirds to your yard is by filling your bird feeder with a sugar water hummingbird food. This is a simple and nice gesture towards these extremely agile and pretty little creatures that come into your yard or garden.
Hummingbirds are amazing creatures that expend an astounding amount of energy every day. Hummingbirds are extremely small birds, typically weighing between 3 and 7 grams, but they require an abundance of energy in order to live. This is because their activity level is extremely high, and their biological clock runs incredibly fast. The heartbeat rate of a flying hummingbird may reach up to more than 1200 beats per minute!
It is due to their astonishing level of activity and also their heartbeat rate that hummingbirds must feed so very frequently, flying from flower to flower gathering nectar, which is the main source of their energy. Nectar contains, in addition to water, sucrose, glucose and fructose, all of which are different forms of sugar. So a sugar water hummingbird food is as close to their natural diet as you can get.
Hummingbirds are voracious eaters, and they have to eat between 5 and 14 times every hour. The stomach capacity of a hummingbird is quite small, and therefore it cannot hold too much food at once. That is why they must feed very frequently so as not to starve. At any given moment during the period of activity, they are only a few hours away from death by starvation! The need to be frequently acquiring food is a major survival issue for them. This is especially true in today’s society when concrete jungles are extending and wiping out forests, trees and flowers.
A tipical human being normally eats about 2% to 4% of their own weight every day. The hummingbird must eat,under normal circumstances, more than 500% of its own body weight everyday just in order to survive! Providing a high-energy sugar water hummingbird food in your bird feeder is one of the best gestures of kindness that you can make towards these exquisite creatures of the air.
