Rufous Hummingbird

The Rufous Hummingbird is the northernmost Trochilidae breeder. Oregon, Idaho, British Columbia, and southern Alaska are its nesting grounds.

Rufous Hummingbirds migrate up to 3,000 miles to western Mexican pine/oak and oak environments alongside Western Tanagers and Townsend's Warblers.  

The Rufous Hummingbird, long a rare vagrant in the southeast U.S., has become more common in winter. Along the Gulf Coast, sightings have increased. This trend is likely caused by a warming climate and more suburban gardens and hummingbird feeders.  

A Wonderful Memory The hippocampus, which controls learning and spatial memory, is the largest avian brain region investigated, occupying up to five times more "brain volume" than songbirds.  

The Rufous and other hummingbirds use their superior spatial memory to locate ideal nectar sources and visit just when the flower has the most nectar.  

Interestingly, hummingbirds can remember feeder locations from prior years in their home territories and migratory paths.  

Dashing Shows Rufous Hummingbird males like the Ruby-throated court females with elaborate flight displays, including high, U-shaped dives. These flights make buzzy, chattering noises from air flowing through the wings and tail, improving performance.
