Volcano Hummingbird: Feathers Garden, Savegre Mountain Hotel and Spa, San Geraldo de Dota, Costa Rica, December 2023 — There at two very small hummingbirds, both endemic to the mountains of Southern Costa Rica and Northern Panama, and so similar that they are always a challenge to separate where they overlap…as they do at Savegre. Generally the Scintillant is found at lower elevations and is replaced by the Volcano at higher elevations…however there appears to be a broad area of overlap in the Talamancas. Males have different colored gorgets…orange for the Scintillant and violet for the Volcano, but I have seen far fewer males than females, and, indeed, saw no males this past December. I am pretty sure both of these shots are the female Volcano. I have shots taken only a few moments later from the same chair at Feathers Garden, of what is clearly the Scintillant (with I will post another day). Compared, the Scintillant has an obviously rufous tail and more rufous under the wings and is very slightly smaller (but we are talking really small hummingbirds already). OM System OM-1 with M.
