Douglas Dewar, Birds of the Plains
“ As it rests on its perch its bright eyes are always on the look out for passing insects. When one comes into view, the bird sallies forth. Very beautiful is it as it sails on outstretched wings. The under surface of these is reddish bronze, so that their possessor seems to become alternately green and gold as the sun’s rays fall on the upper or lower surface of its pinions. Its long mandibles close upon its prey with a snap sufficiently loud to be audible from a distance of five or six yards. ”
