The Black-chinned Hummingbird (Archilochus alexandri) is essentially a species of the western U.S. and Mexico, although vagrants have occurred some winters all the way to the east coast. The female on a nest in the top two shots as well as the same bird feeding young was photographed in May, 2005, in Travis Co., Texas with a Canon EOS 1D Mark II and EF 600mm F/4 L IS lens and 2X extender and fill flash.
