The Rufous-tailed is abundant in most humid areas of Costa Rica. Like most other hummingbird species, they love to come out in the rain. Males are difficult to differentiate visually from females, but only the males chirp. Their incessant squeaks sound like rusty gears.
Although only 4 inches long and 2/10 of an ounce, it is very aggressive, often chasing other hummingbirds, even larger ones. The nest is a compact cup of plant fibers, down, dead leaves and cobwebs. An outside decoration of lichens and moss helps to camouflage it so well that even knowing the location of a nest, we have had to wait for the female to come feed her young in order to be able to see it.
