Grenada Hummingbirds (1 Viewer)

In Grenada a few years back, in June, I saw four types of hummingbirds -

Purple-throated Carib
Green-throated Carib
Antillean Crested Hummingbird
and one which I understood at the time (although my bird book was basic and didn't cover it) to be a Rufous Hummingbird. It was much harder to find than the other three.

I believe there are no other hummingbirds commonly seen in Grenada.

But now I understand that the rufous hummingbird is a summer visitor to NW USA and Canada and winters in Central America, so that would make this ID seem unlikely. Can anyone confirm what this was?

Grenada is supposed to have four species of hummingbirds according to Raffaele et al. You correctly name the first three, and the fourth one is Rufous-breasted Hermit, which could become "rufous hummer" if someone is a little sloppy. Local names are reported to include Brown Hummingbird and other variations of brown.
