A relatively large hummingbird, bigger
than the Blue-tailed Emerald,
the other common hummingbird on Bonaire. 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.
