Kinglets are tiny insectivores that actively forage for insect and spider eggs on the undersides of foliage. They weigh less than an ounce and are among the smallest of songbirds. They often hover in front of a branch, gleaning food from its tips and undersides. Kinglets often flick their wings as they move about.

Hummingbirds enjoying the rain at San Pablo's Retreat and Guest House, Valencia, Trinidad and Tobago.
A Ruby-throated Hummingbird photographed in my backyard over the weekend, seen here feeding from a Petunia. First time this summer I have took to my backyard for these guys. Figures when I went out side all the clouds rolled in and chocked out all my light. Other then that, I was fairly happy with my first attempt of the summer.

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.

Ruby resides on my refrigerator. She is a magnet.....for attention!
She came with a bikini, and some type of pajama/summer outfit.
She loves her new golfing clothes. I told her not to accept any text messages from a man named Tiger!
Merry - Merry Happy - Happy!

A male Ruby-topaz Hummingbird feeds in the garden near the veranda at Asa Wright Nature Center in Arima, Trinidad. Recorded on 03/07/2016.
MOC: Ruby Roadster. The profile is long (maybe a bit too long for the scale) and sleek - I think this is my favourite angle.
Ruby Beach is the northernmost of the southern beaches in the coastal section of Olympic National Park in the U.S. state of Washington. It is located on Highway 101, in Jefferson County, 27 miles (43 km) south of the town of Forks.
A male ruby-throated hummingbird comes in for a landing on a feeder.
It's always eventful around the hummingbird feeders. Ruby-throated hummingbirds are working on bulking up for their long journey to overwintering grounds in Central America.

This bird has been hanging around and utilizing a sapsucker's drillings. Central Oklahoma Cross Timbers. Hyper-active teeny little birds that drive a photographer crazy.
