According to Storrs Olson the Atlantic Lesser Frigatebird should be treated as full species.
The Atlantic Lesser Frigatebird (Fregata trinitatis) is elevated to a separate species from Fregata ariel of the Indo-Pacific based on plumage differences and greater robustness of the rostrum and wing bones. The species now occurs only on the remote South Atlantic island of Trindade (South Trinidad) over 1,100 km east of mainland Brazil, although fossils establish that it once also occurred at St. Helena. Fregata trinitatis no longer breeds on the main island of Trindade and is only known to nest with certainty on a small rocky islet on the southern coast, where there may be fewer than 20 breeding pairs.

Atlantic Lesser Frigatebird: a species on the verge of extinction?
19 Jan 2018 - 12:12 -- Chris Sharpe
Lesser Frigatebird Fregata ariel comprises two subspecies found in the Indo-Pacific, and a third, trinitatis, breeding on the Atlantic island of Trindade, 1100 km off the coast of Brazil. Plumage and structural differences suggest that trinitatis may merit recognition as a species, Atlantic Lesser Frigatebird, making it one of the world’s rarest and most threatened seabirds. Fewer than 20 breeding pairs were found on a small islet alongside Trindade in 1975/76, with just six birds recorded over 60 days of surveys in 2013. The decline of trinitatis may have been caused by a combination of factors, from direct consumption of eggs and overfishing, to the effects of introduced mammals: feral pigs, goats and cats have been extirpated, but house mice remain abundant and are likely to prevent recolonisation of the main island. Taxon trinitatis would be a Brazilian breeding endemic that is already considered Critically Endangered at the national level.

Or vice versa, the thread is there (only more recently started, same topic, parallel threads).
In my mind Melanie posted in the proper (original) one.
I assume Kovalik, who started both, simply forgot that he started this one, back in 2014 ...

missing the neotropics
Retaining Magnificent Frigatebird as an english name for the LESS widespread of the children species of a split is very unlikely. Generally if it's a true parent-child split, it's desired that neither child species retain the common name unless one child is far more widespread and more frequently encountered, in which case name stability outweighs the desire to avoid confusion by having two definitions of a species operating under one common name.
Pamela Rasmussen's proposal to SACC includes this comment:
"Obviously, Magnificent Frigatebird could be retained for the vastly more widespread rothschildi but it would no doubt cause confusion, given the retention of magnificens by the Galapagos form. (Consider though that we have all learned to live with Great Frigatebird being Fregata minor, while Lesser is F. ariel.) Another option might be American Frigatebird, but of course Galapagos are part of the Americas, and in fact American Man-O-War Bird was used by Hellmayr and Conover (1948) for their monotypic, widespread F. magnificens (including the Galapagos population). I recommend retention of Magnificent though as being the least disruptive option."

Could always change the spelling a bit, how about Magnicifent Frigatebird? Or perhaps just Frigginbird?

we always used to call it Fragnificent Maggotbird - but that's just silly.

Frigatebirds are already a mess, what with Fregata minor being Great Frigatebird. A little more wont hurt.

Of names already suggested, why not Galapagos Frigatebird & Rothschild's Frigatebird? That would avoid the bother of having to know when something was written to be sure which 'Magnificent' Frigatebird concept was being discussed.

Now Rothschild's is a truly useless name... A geographic description is the best you can do with most species of this overly uniform group, so American Frigatebird has my preference!
It does not really matter that "American" was used for the monotypic magnificens in 1948 – the fact that the Galápagos Islands are "American" as well is not a very convincing argument to reject it.

Well, it would give us the opportunity to see how many ways there are to misspell it. But yeah, we should be trying to avoid eponyms at this point in time.
