In the Northeast, our only breeding hummingbird is the Ruby-throated Hummingbird. Their nest is hard to find (it's a little bigger than a quarter), but is a sight to behold, made entirely of spiderweb encrusted with flakes of lichen -- a masterpiece of engineering and design! For safety from predators, they seem to favor building their nests on branches overhanging water.

A Kinglet pauses on a wire between trips to the suet feeder. This tiny bird hovers like a hummingbird at times while looking for a perch, perhaps.

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.

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.
Our beautiful world, pass it on.
MOC: Ruby Roadster. The profile is long (maybe a bit too long for the scale) and sleek - I think this is my favourite angle.
