Hi, Stephen! 
I've just seen this great list of Hummingbirds you've got! 
I've never seen the Black Jacobin or a male Black-crested Coquette but Snowcap, Purple-crowned Fairy and Fiery-throated Hummingbird are certainly among my top-five ones seen. Which are the other two? I don't know... probably the Violet Sabrewing (what a stunning bird it is!!!) and the Stripe-tailed Hummingbird. Well, and the tiny Coppery-headed Emerald is not bad either! 
Thank a lot for sharing your list! 
Cheers!
Thanyou Marian !
Yes it is very difficult coming up with a top-5 , they are all so amazing . The Coppery-headed Emerald is such a fantasic bird !
Black Jacabin is one I saw in Brazil but never photographed , actually it was a miserable rainy day but I saw several in the rain, I wish I had more time viewing them in better conditions. I liked Brown Violetear from Costa Rica alot too !!
..and oh yes Violet Saberwing ! and the Green Hermit was neat too !!!
