Jamaica (ˈdʒəˈmeɪkə} is an Island nation of the Greater Antilles, in length and as much as in width situated in the Caribbean Sea. Incidentally, the bird known to scientists as Trochilus polytmus, is the name-bearer of the whole hummingbird family, the Trochilidae. Hummingbirds are Birds in the family Trochilidae, and are endemic to the Americas. Formerly believed to be conspecific with the Black-billed Streamertail of extreme eastern Jamaica, the latter is now considered a distinct species (Trochilus scitulus). Conspecificity is a concept in Biology. Two or more individual Organisms Populations or Taxa are termed conspecific if they belong UserPolbot. -->The Black-Billed Streamertail ( Trochilus scitulus) is a species of Hummingbird in the Thus, T. polytmus occurs west of a line from Morant Bay following the Morant River, and via Ginger House and the middle Rio Grande to Port Antonio (Gill et al.
