While we have known for some time that hummingbirds cannot survive on a diet of sugar water and/or nectar alone. These tiny birds must also capture and eat insects to maintain a proper balance of proteins and nutrients. That being the case, have you ever wonder how many insects a hummingbird must consume in a day?
Dr. Gregor Yanega of the National Evolutionary Synthesis Center has provided us with the answer. According to Dr. Yanega, “Hummingbirds need the equivalent of 300 fruit flies a day to survive.”
