Just before they answer the call to travel south, hummingbirds eat in excess to build a layer of rich fatty fuel just under their skin. You can notice the extra fat along the belly, back, and throat. A hummingbird actually gains 25 – 40% extra body-weight to have enough fuel to migrate thousands of miles south. You will notice them getting fatter and fatter and then one day they fly to their wintering grounds.
