Two ruby-throated hummingbirds gracefully hover around a vibrant red feeder, with their delicate wings blurred from rapid movement. Set against a clean, bright background, the focus is on the birds' vibrant feathers and the feeder's striking color!!!
Just sitting in the house a little under the weather so I decided to work on some photos since I am tired of laying in bed. This was from my visit to the coast last May.
Ruby relaxing on my bed, she has had her desexing and hernia op today and I am a nervous wreck till she comes home!

This experiment was an attempt to recreate the fluorescence of chromium activated corundum (aka 'ruby'). Aluminum hydroxide was mixed with 1-4 drops of Cr(III) oxide in a basic solution. This was placed on a small amount of aluminum sulfate in an aluminum foil container and a bit of water was added.
The sample was then heated, first with a propane torch until the water was removed and then with a MAPP gas torch until the aluminum sulfate expanded into foam, trapping the aluminum hydroxide which was calcined into aluminum oxide by the torch's flame. (at least that was the plan)
Shown also is a natural ruby from Mysore, India.

The Ruby Lake National Wildlife Refuge was purchased from Albert Hankins and established in 1938/39 by the U. S. Department of the Interior Fish and Wildlife Service.The refuge covers 37,632 acres in the south end of Ruby Valley. At one time the area was covered by a 200 foot deep, 3000,800-acre lake known as Franklin Lake. Presently 12,000 acres of marshland remain on the refuge grounds. North of the refuge is a 15,000-acre seasonal wetland that is now referred to as Franklin Lake.

RUBY-THROATED HUMMINGBIRD-07215016.jpg
An immature Ruby-throated moving in on one of the feeders at Strawberry Plains Audubon Center in Holly Springs, Mississippi.
So here's the story, I was searching for copperheads locally (to no avail) and had to leave. On the way back home, the road was winding along Deer Creek. I was looking for a parking area along the river to stop and look for some dragonflies. I finally found a pull off on the side of the road and decided to stop. After walking along the river for twenty minutes or so, and I saw a giant insect fly by. As I turned, I saw the giant insect feeding at a cluster of flowers along the river and it turned out to be a female hummingbird. Unfortunately, the patch of flowers was fairly large and it took a few tries to get her in the right area of flowers with a somewhat decent background. So here is the result :)

Ruby-throated hummingbird. I was setting up for some flower shots and this hummingbird came out of nowhere and kindly waited for me to pay attention.

So Ruby and Moose had their playdate this morning. They were together for a couple of hours and it went quite well, I think.
They didn't flat out fight at all, but there were some rocky moments. Moose tried to hump Ruby a few times, and pulled out a mouthful of her fur at one point. Overall, Moose showed more interest in Ruby than Ruby did in Moose. But after an hour or so, Ruby at least tolerated Moose, allowing him to groom her and they sat close together for a good while.
The start of a loving relationship? We'll see. I'm taking Ruby back over to the sitters next week and let her stay there with Moose for a couple of nights.
I spend much-too-much time observing my garden "bee-hotel". Several different bee and wasp species are using it for nesting and others for "roosting". I could see the bluey/green face of this ruby-tailed wasp deep in the hole all day today. When the sun was at its warmest in the afternoon, it finally came to the entrance and gave a brief opportunity for a photograph before flying off.
My Ruby-crowned kinglets are taking full advantage of the suet feeders. This was shot on the 12th, when there was still snow on the ground here. Luckily, my area escaped additional snowfall, though areas just south and farther south of here got some.

Joe Parks and I celebrated this year's Thanksgiving in beautiful, FREEZING cold Olympic National Park. I'd been hoping to visit Olympic for years, and it didn't disappoint! We spent the better part of Thursday driving up from Portland, arriving just in time to catch the sun going down over Ruby Beach.

Ruby Falls is a 145-foot high underground waterfall located within Lookout Mountain, near Rock City and Chattanooga, Tennessee in the United States.
It was such a wonderful place and a wonderful Waterfall that they switched on the lights to capture the falls for only 2 Mins :(
