This is a long named bird and long named plant! The Powdery Alligator-flag doesn’t look like it would have much to feed a Hummingbird but this one spent several minutes investigating this single stalk.

After circling a few times she perched for a short rest.

I was able to move to a slightly closer spot, then a cloud covered the sun. And as is the way with Hummingbirds, zip and she was gone.

Lovely shots, especially the first one!
Thank you, David. This was a most cooperative hummingbird, for a minute or so!
