I just "know" this was not the usual ruby throated hummingbird that is so common in this area.
"Different sound, different look, different behavior".
Just happened to have my aim-and-shoot camera handy.
Did not see a brilliant color, either purple or red, beneath the chin, just black. Hummingbird's back was an obvious metallic green.
It was drinking sugar-water from the feeder.
