The Rufous-tailed Hummingbird, Amazilia tzacatl (linked to eBird) is a Central American bird overlapping only into the northern edges of South America and found literally all over Costa Rica as can be seen in my GALLERY, Rufous-tailed Hummingbird. It has long been the dominant hummingbird in my garden, often chasing off other species, though now I am seeing just as many or more of the Blue-vented Hummingbird. Here’s two shots of this species in my garden recently, the first a juvenile or immature adult (smaller) and the second a mature adult . . .
