A long- tailed Hawk, too far away to make certain of, I supposed 

 was a Cooper's, but he alighted on the ground and then I knew it must

Each species has its own habits and sounds as well as colors, that 

 help in its recognition, but the most useful all-around label-marks are 

 those of color -pattern or uniform.
