This little jewel of a bird was in a garden at the Arenal Observatory Lodge, in Costa Rica.
Rufous-tailed Hummingbirds were all over and easy to see, as they are bold and territorial.
The food of this species is nectar, taken from a variety of flowers, including Heliconias and bananas. Like other hummingbirds, it also takes small insects as an essential source of protein. Rufous-tailed hummingbirds are very aggressive, and defend flowers and shrubs in their feeding territories. They are dominant over most other hummingbirds.
