April: Full Speed Ahead: Peak Migration
In April people on the Gulf Coast start watching for hummingbirds to arrive. Males arrive first and establish a territory. They look for a place with many flowers and high perches. They show off with flight displays, diving, dipping and looping to attract a female to their territory. If she likes his display, she will mate with him. If not, she moves on to another territory. Breeding begins in the southern states where flowers are in full bloom, and where the first egg can be laid as early as the second week in April. Hummingbirds don't mate for life; they don't even stay together to raise the babies.
