Ruby-throated hummingbirds (Archilochus colubris) must drink loads of nectar and eat many insects to build up fat reserves necessary to fuel their migratory flight first to the Gulf Coast then on to their tropical winter homes in Central America, southern Mexico or on some Caribbean islands. Males leave as much as a month before the females and fledglings who nest in that region follow them on the southern journey.
