![]() ![]() I hope you enjoyed this information about the hummingbird heart. Slowing the hummingbird heart allows them to survive until morning when they can resume feeding. When they’re awakening, their heart rates increase, and they vibrate their wing muscles to generate heat for the perfect blood supply. This ranks the blue whale officially as having the slowest heartbeat in the world. The heart has an excitatory-conduction system that spontaneously and regularly generates electrical impulses (action potentials) and spreads throughout the heart (Fig. However, they take around 20 minutes to return to their normal state. A dog’s heart rate averages around 70-120 bpm, cats rest at around 120-140 bpm, and the blue-throated hummingbird’s heart beats about 1260 times per minute. Heart electrical activity Excitatory and conduction system. Hummingbirds enter a hibernation-like state known as torpor each night, which aids them in conserving their energy. How Do Hummingbirds Return to the Normal State After Torpor Typically, hummingbirds wake from torpor 1 to 2 hours before dawn. Wing Speed and Heart Rate These little creatures fly about 25 miles per hour and zoom even faster when the wind pushes them along. ![]() Heart rate is 250 beats per minute when you’re resting. During the flight, the average heart rate is 1200 beats per minute. They are able to store only enough energy to get them through the night. The heart rate of a hummingbird is incredible. A hummingbirds heart is about 2.5 of its weight, which makes it one of the largest hearts in the animal kingdom. If the hummingbird was not able to slow it’s metabolism down in this way, it would starve to death before morning. This hibernation-like state is called torpor, and allows the hummingbird to get through the night without feeding. During this time when the hummingbird heart beat is slowed, their metabolism is also slowed way down. The heart beat of a Blue-throated hummingbird, was once measured at 1260 beats per minute, which happens to be the fastest hummingbird heart beat ever measured.īecause of the rapid movement of their wings, that is needed to maintain flight, they need a high metabolism and thus a high heart rate to maintain it.ĭuring times when food is not readily available or at night, the hummingbird heart rate will slow to as low as 50 to 180 beats per minute. On the other hand, when the hummingbird is in flight, the hummingbird heart will beat on average, 1200 times per minute. However, their calories come from very different sources. Both species may consume twice their body mass per day in food. Humans, by comparison, have a resting heart rate around 72 beats per minute. The hummingbird heart, will on average, beat about 250 times per minute, if the hummingbird is just at rest. (To support that, they have heart rates up to 1,000 beats per minute) To fuel that high metabolism, shrews and hummingbirds need to feed at high rates. And the hummingbird’s heart beats at astounding rates, typically 500 to 1,200 beats per minute, depending on level of activity. The Hummingbird Heart, beats extremely fast
