During these flights, air rushing through the wings and tail produces a variety of buzzy, chattering noises that enhance the performance.įemale Rufous Hummingbird feeding young. Like other hummingbirds, including the Ruby-throated, male Rufous Hummingbirds court females with elaborate flight displays, including steep, U-shaped dives. They get this nutritional mainstay from tiny insects and spiders that they capture in the air and on foliage and flowers. But in addition to nectar, Rufous and other hummingbirds also need protein, both for themselves and for their fast-growing young. To keep its “tank” full, it must feed almost continuously throughout the day in short spurts of less than a minute at a time, often visiting more than 1,000 flowers in a day. Like all in its family, from the Esmeraldas Woodstar to the Blue-throated Hillstar, the Rufous Hummingbird needs a lot of fuel to sustain its nonstop daily activity. Remarkably, hummingbirds can also remember feeder locations from previous years, both on their home territories and along their migratory pathways. With enhanced spatial memory, the Rufous and other hummingbirds pinpoint prime locations of nectar, their main food source, and keep track of which blooms are at peak, visiting only when the flower provides its richest nectar supply. Research has revealed that the area of a hummingbird's brain related to learning and spatial memory - the hippocampus - is proportionately the largest of any bird group studied to date, occupying a percentage of “brain volume” up to five times larger than that found in songbirds, for example. This change is likely due to a warming climate, combined with an increase in suburban garden habitats and hummingbird feeders. Sightings have piled up particularly along the Gulf Coast. In recent years, the Rufous Hummingbird has been seen more regularly in winter in the southeast U.S., where it was once a rare stray. Traveling up to 3,000 miles to wintering grounds in western Mexican pine/oak and oak habitats, Rufous Hummingbirds can be found with other migrants such as the Western Tanager and Townsend's Warbler. It nests from Oregon and Idaho north through much of British Columbia and into southern Alaska. The Rufous Hummingbird is the most northerly breeding member of the family Trochilidae. It's also known for its stunning migration, one of the longest of any bird its size. The Rufous Hummingbird is a standout in a family of already incredible American birds, and not only because of its moxie. It dominates feeders and choice flower patches, chasing away other hummingbird species such as the Calliope Hummingbird.
