The eastern bluebird consumes an average of 0.14 ounces (4 grams) of food each day. This amounts to roughly 12 percent of its body weight.

       That may not sound like a lot when you consider a ruby-throated hummingbird can consume up to 50% of its weight daily. However, a two-hundred pound human would have to chow down 24 pounds of food every day to eat the equivalent amount of food as an eastern bluebird.
