Tobago, Robinson Crusoe's Island described in Daniel Defoe's, Robinson Crusoe, novel[a] of 1719, has eight known species of hummingbirds six of which, the rufous-breasted hermit, white-tailed sabrewing—this species is also found in northeastern Venezuela—black-throated mango, ruby-topaz hummingbird, copper-rumped hummingbird and the white-necked jacobin, are routinely seen, and the seventh and eighth, the blue-chinned sapphire and green-throated carib, are occasionally reported. The green-throated carib is an itinerant visitor from the eastern Caribbean; and, except for the white-tailed sabrewing, all of them are shared with the island of Trinidad.
The white-tailed sabrewing stands out in Tobagoˈs culture amongst its hummingbirds as, locally, it has been fondly renamed "Campy"; possibly a contraction of the longer scientific name "Campyloperus ensipennis." The species was thought to be extirpated in 1963 due to the passage of Hurricane Flora, but survived, and was first spotted again in 1974.
These hummingbirds, amongst other bird species, together with an abundant variety of butterflies and picturesque scenery, coves, bays, beaches, rain forest, etc., add charm and enhance the island's ambience of tranquility and natural beauty. The PowerPoint presentation below attempts to exhibit some aspects of that natural scene.
Nearly all these birds and, really, Tobago's wild outdoors can be enjoyed at Cuffie River, Gilpin Trace on Tobago's Main Ridge and Adventure Farm, amongst other birding spots.
