DIRECTIVE MARKS OF HAWKS AND OWLS 



L3 



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

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

 be a Marsh Hawk. 



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

 help in its recoji;nition, but the most useful all-around label -marks are 

 those of color -pattern or uniform.
