The Black-throated Mango is common at Luck's feeders starting in about September and the rest of the year. It competes with the Sombres for numbers and feeder slots and is very close in size. This is the male and it is the only Mango in the area. Note that the entire throat and belly appear black. The beak is slightly curved but about the same proportions as the Sombre. The wings come to the tail tip and are just slightly longer than the Sombres proportionally. You can see a male Violet-capped Woodnymph to the left side of the feeder. Note the long tail and the gap in the middle. Both birds appear shining green on the back whereas the Sombre is dull. Luck's shot showing full colors of male.

This shows the fan of the male tail, though we can get a better shot I hope. Male tail has dark red over most of the tail except the central feathers. No white tips. The lateral feathers can be dark tipped but the more mature males have some red all the way out. Sombre is perched to the right showing the close sizes. Tail flared on the Mango never shows the individual pointed feathers like a Sombre tail. See Luck's much better male tail here.

This shot was taken by me, susu and Marcia at what must have been exactly the same moment, or the screen froze, I don't know which. But they were exact. That is the female Mango to the right with the distinctive black belly stripe. This shot was taken in September so they are all adult females with that stripe for now. Later the juveniles of both sexes have the same striping. No other hummer has that look. The stripe is generally heavy and irregular and females can be separated from each other by the stripe shape. The tail of the adult female is distinctive. She has some red at the lateral bases and then a darkened section and then white lateral tail tips. We don't have a flared shot of it yet. Juvenile males when they appear will have male tails and female throats and bellies. That is a male Mango on the left side of the feeder in feeding flight. 

Another female Mango in September. The black lines can determine females like fingerprints. And what a strong black band this girl has.

This shows the closed Mango female tail and back. Note the white tips with the darker line above this. And it is pretty squared when closed. The back will never be this green on a Sombre back and the Sombre will never show this white. Note the red areas on the female tail are covered in this position. Bananaquits are often present for size. They are 10 cm birds. You can see this Femango is larger than that here. Mangos range 12.5 to 14 cm.

The female Mango to the right has the tail fanned for us here by a slight miracle. Note the red bases laterally and then the black band and terminal white tips. You can almost always see the female tips in any position and her large size overall. Females being even larger than males in the Mango. That is a Glittering-throated Emerald on the left side. 

Really, who can see too many mama Mango bellies? Marcia Braga again.

Triple males in the ring around the feeder. If I was really fast I could catch five or six in frame in the busy September feed times.

And a quick spin off to the right to threaten whoever was up there and back. Male on the far side was not the one threatened. But surely, he was impressed?

Three Mangos and, well, you know the other bird now. Susu's shot.

And really what can you say about that? Mango female flip up maximum. What male Mango's see in their dreams I guess? Marcia's shot.
