The Rufous Hummingbird is a visitor to the Santa Rita Mountains south of Tucson, and one you might spot either hiking in or visiting Madera Canyon. They are migratory, only visiting the Santa Ritas on their trips to and from Mexico. They have the broadest range, breeding farther north than any other species.
This is one of the most aggressive species of hummingbirds, attacking other hummers and birds at feeders or pushing them away from flowers. They have no problem taking on birds twice their weight. It doesn’t matter that they are just passing through, and fight with hummers that are natives.
The male Rufous Hummingbird is colored in brilliant orange, while the female of the species is green and orange. They not only eat nectar, but enjoy insects and spiders as well. They are known to catch insects in flight.
