How Often Do Hummingbirds Eat

Are you wondering how often do hummingbirds eat? These tiny little creatures require an enormous amount of food for their size, which makes their eating habits an area of fascination for many bird enthusiasts. Frequency of feedings is critical to a hummingbird’s survival.

How Often Do Hummingbirds Eat – Typical Patterns

Hummingbirds spend approximately 10 – 15% of their time eating, and the rest of their time conserving their energy until the next feeding. According to research reported on Hummingbirds.net, hummingbirds break their eating down into several meals throughout the day, where they consume enough calories to allow them to rest for a period before going out to find the next meal.

Just how often a hummingbird eats a meal depends partly on what they are eating. Hummingbirds get protein by dining on small insects, but the bulk of their food comes from nectar in flowers. The sugar content of the nectar they eat determines how many meals they have to eat in a day. The higher the sugar content of the nectar they are eating, the fewer meals a hummingbird has to have. Hummingbirds are able to determine if a flower’s nectar has a sugar content of less than 10%, and it will avoid those nectar and move on to something with more sugar. However, sugar contents can still vary widely between the nectars that they do eat, which can have a large impact on how often they must eat.

For instance, in a study reported on Hummingbirds.net, researchers provided a hummingbird with a sugar and water solution as a food source. The bird initially ate five meals of approximately 1/100 fluid ounces each in one hour. The researchers then diluted the solution by half. The size of meals did not change, but the hummingbird ate 14 meals in one hour, thanks to the reduced caloric content of each meal. Scientists believe that this pattern of eating more frequently, rather than eating larger meals to compensate for lower calories, plays out in nature as well as in the lab. At this rate, hummingbirds may eat a few hundred meals in a day.

The need for hummingbirds to eat often is why they tend to stick close to a good food source once they find one. They will usually feed and then rest nearby wherever they have eaten so their next meal is close and so they can drive off any other birds that may come looking for food. If you have a hummingbird feeder in your garden, you may notice the same bird feeding there and spending their days in your yard for this reason.

How Often Do Hummingbirds Eat – Nighttime Habits

During their active times, hummingbirds can die of starvation within the space of a few hours. However, hummingbirds cannot keep up this constant schedule of mealtimes around the clock. Though they store some food during the day to keep them going through the night, the most important part of their overnight survival is energy conservation. This reduced energy state is called torpor. Torpor is a kind of mini-hibernation period in which body temperature and metabolism are slowed by as much as 50%. Hummingbirds also rely on torpor to conserve energy consumption and reduce their body temperature in cold temperatures. It can take a hummingbird up to an hour to come out of their torpor state after they have slept.

Why so Hungry?

Just why do hummingbirds eat so often? Their appetite is a byproduct of their incredibly high rate of metabolism. Hummingbirds have faster metabolisms than any other animal. Their metabolisms are approximately 100 times faster than an elephant’s metabolism. They have to eat meals frequently to keep up with the demands of their bodies. During an average day a hummingbird may eat several times its weight in food.

Their fast metabolisms are the result of their physical activity. Hummingbirds beat their wings anywhere from 12 to 90 times per second. They can also fly at speeds of up to 60 miles per hour. Their frequent meals help them keep up this rate of activity.
