A relatively large hummingbird, bigger than the Blue-tailed Emerald, the other common hummingbird on Aruba. Both male and female Ruby-topaz Hummingbirds have reddish, rounded tails unlike the blue, forked tail of the Blue-tailed Emerald. Male Ruby-topaz Hummingbirds have a beautiful orange throat and reddish head, though in poor light it can look dark. We rarely see this species at the flowering shrubs around hotels in contrast to the Blue-tailed Emerald that often occurs there. Spanish Lagoon often has good numbers of both hummingbirds.
