Do you suddenly have a lot more hummingbirds at your feeders? If so, you’re witnessing the start of their fall migration southward toward Mexico, Central America and the Caribbean. In addition to the adults that traveled here to breed in the spring, the young that hatched out this year are heading out, too.

With the breeding season passed and "refueling" on their minds, hummingbirds seem to tolerate each other at feeders more during late summer than in the spring. The males are the first ones to migrate south in July and August. Females typically stay around until September.
