From the publisher:
"Each bird species is shown in a large primary photo, with additional photos showing a variety of angles and poses; close-ups of feathers, feet and other details; and the bird in its natural habitat. Key information on habitat, feeding, physical characteristics and other helpful facts are included to help artists create accurate works of art. Four step-by-step demonstrations show how to use reference photos to paint beautiful birds."
