Ruby throated hummingbird.

I dont think the emerald has a yellow throat- there are umpteen species of emerald hummingbirds that do. The ruby throated is called that because it is just that!!- it has a ruby throat. You might like to google a Crimson Topaz Hummingbird- largest hummingbird in Brazil- that fits all the criteria.
