Hummingbirds have uniquely high metabolisms that keep them busy searching for and eating food for the most part of their days. Most people would be surprised to know that a hummingbird’s diet consists of insects like ants, mosquitoes, gnats, and small spiders. These bugs help fill their stomach and provide them with protein. But it is most commonly known that these small, fluttering birds consistently seek out and need nectar to supplement their diet and overall well-being.
