Ruby-throated Hummingbirds

Ruby-throated Hummingbirds

Ruby-throated Hummingbirds are able to fly across the Gulf of Mexico, a distance of 500 miles, in one 20-hour non-stop flight. This requires more calories than the bird's weight, so they prepare by doubling their fat mass. They expend the entire caloric reserve during the flight.
