Ruby Throated Hummingbirds have arrived, coming from as far south as southern Mexico and northern Panama. Since hummingbirds lead solitary lives and neither live nor migrate in flocks, an individual bird may spend the winter anywhere in this range where the habitat is favorable, but probably returns to the same location each winter.

Some will skirt the Gulf of Mexico and follow the Texas coast north, while most apparently cross the Gulf, typically leaving at dusk for a nonstop flight of up to 500 miles, which takes 18-22 hours depending on the weather.

Hummingbirds are carnivores, nectar is just the fuel to power their flycatching activity. Ruby-throats begin moving north as early as January, and by the end of February they are at the northern coast of Yucatan, gorging on insects and spiders to add a thick layer of fat in preparation for flying to the U.S. 

The initial urge to migrate is by the shortening length of sunlight and has nothing to do with temperature or the availability of food; amazing that nature follows the Light. The sun, moon and stars, they have a purpose. Amazing how it all comes together as designed.
