Scientific name: Amazilia yucatanensis
The Buff-bellied Hummingbird is really a Mexican species that just reaches southern Texas. With its large size and aggressive nature, it usually dominates other hummingbird species at feeders. Besides feeders, Buff-bellied Hummingbirds can also be attracted by sprinklers, in which they will bathe.
Buff-bellied Hummingbirds are primarily nectar feeders like most hummingbirds, but also feed on arthropods which they may glean from plants, or even fly-catch in midair. Long calls are given when chasing another hummingbird away from a favored food source.
