During the fall migration, the birds fly across Texas moving between 25 to 30 miles per hour. Some migrants fly non-stop across the Gulf of Mexico while some move inland down the Texas coast. According to the Texas Ornithological Society, of the 320 species of hummingbirds in the New World, eighteen hummingbird species live at some time in Texas. Hummingbirds have evolved a delicate relationship with flowering plants. It has been estimated that one hummingbird requires 5,000 flowers a day to supply its daily energy requirements.
Plants benefit from the relationship by receiving pollinating services from the feeding hummers.
Some hummers also hunt and eat insects. In Rockport Texas, which is north of Corpus Christi, there is an annual celebration for the south-bound hummers. In early September, many hummingbirds converge on this small town, building strength for their trip across the Gulf of Mexico, towards their over-wintering habitats in Mexico.
