Here are photos of the six common hummers found on Tobago. Going through my images, I realized I failed to get a photo of the female White-tailed Sabrewing. Otherwise I got photos of both the male and the female of the other species. The White-tailed Sabrewing is the rarest hummingbird species on Tobago, so maybe not so strange that I missed the female.
