I have some doubts on the explanaition on mango
in the key:
By confusion Albin 1731, gave the name "Mango Bird" to a hummingbird, the Jamaican Mango, an error perpetuated by Linnaeus 1758. However, Olson & Levy 2013, have shown that Albin's "Mango Bird" was undoubtedly the Indian Golden Oriole Oriolus kundoo; "60. TROCHILUS. ... Mango. 16. T. rectricibus subęqualibus ferrugineis, corpore testaceo, abdomine atro. Mellivora Mango. Alb. av. 3. p. 45. t. 49. f. 2. Habitat in Jamaica." (Linnaeus 1758) (Anthracothorax).
If I look at Albin Plate 49 see attachement, I cannot identify an Indian Golden Oriole
at all. And one page later we can read in the other attachment.
This Bird I had by the Name of the Mango Bird, which I believe to be an imposed Name: It is one of the Humming Birds, the Head, Black and Wings were a mixtrure of copper Colour, red and gold interchangeably mixt, very beautiful to behold; the Breast, Belly and Thighs were a velvet black intermixt with shining green; the Tail is a little more than an Inch long; The Feathers of a mixt Colour, of blew, red and green; the Bill and Legs are of blewish Colour. In the year 1701, when I was at Jamaica, I took one of these Birds in the dusk of the Evening with her Nest, which was built with Cotton in the Branches of the Phyfick-nut Trees growing in that Island, in which was two finall white round Eggs as big as Peas;
I have no clue how Olson & Levy 2013 came to their conclusion.
Anyway no idea what Mango means. I doubt is the same etymological origin as the fruit Mango
