Comparison of fluorescence emission spectra of ruby (top) and synthetic phosphor CaAl655 (bottom).
The ruby was excited with 409nm light and the synthetic with 368nm +311nm light.
The images were then digitally filtered with a red filter to remove the blue noise.
Ruby-throated Hummingbirds can be fiercely territorial and this male, with his gorget and the feathers around his bill showing signs that the territorial squabbles sometimes get downright physical, is standing guard over "his" flowers and feeders bathed in the very last rays of the setting sun.

This location was built and opened in 1998.
Here's the thing about getting a good shot of a male ruby-throated humming bird's gorget (throat feathers). There has to be light facing the bird in just the right way for the feathers to iridesce. Otherwise, his neck just looks black. That's where a flash comes in handy.
Before my mother died, every year, she would set out the hummingbird feeders in September, because that's when the little birds make their migratory path through my part of southeast Texas. Mom and I had a deal: she would cook up the hummingbird nectar and fill the feeders and I would then hang them up for her (because it entailed a step-ladder to do that and she was 89 and there was no way I would let her up on the ladder).
The last time I was able to photograph these amazing little ruby-throated hummingbirds was in 2014. I just stood there with my Canon 1DX and 100-400mm lens and handheld the shots because they were so fast, I could barely get them with the camera on the tripod.
Yes, I used a flash because that helped freeze the action and get a good clear image,

Ruby Dew, one of my fellow students, and an absolute natural. It was a challenge to remember to breathe while she was performing. Oh yeah, and I had to follow her in the show.
No pressure. Except for that whole breathing thing.
