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.
Amazing! We have five fledglings in one nest now. They have to consume a lot to in order to rear their young, I guess.
What great news! My bluebirds have not hatched any eggs yet.
