143hzexcel.jpgThese tiny birds beat their wings an average of 25 times per second, so it is obvious that they use a lot of energy just flying. Even though the nectar they eat is high calorie, they need to eat as many as 2,000 times a day! Even when resting, the hummingbird uses a lot of energy. This is because it needs to keep its flying muscles at a high temperature to be ready for instant take-off. Our hummingbird feeders offer some simple fuel for these fascinating birds and are even more useful if they have perches for the hummers to land on and rest a little. During the day, a hummer’s heart beats 500-1200 times a second, but during the night, a hummingbird ruffles its feathers and allows it’s body to cool. It’s heartbeat slows down so much that it is almost undetectable. The bird is basically hibernating at this point, but it does it every night! The more I learn about these amazing birds, the more I enjoy watching them at our hummingbird feeders.
