ILLUSTRATIONS. 
The illustrations in this volume are designed to aid the student in 
identifying birds in their haunts by giving, in color, those markings 
whick most quickly catch the eye. They do not pretend to be perfect 
reproductions of every shade and tint of the plumage of the species 
they figure, but aim to present a bird’s characteristic colors as they 
appear when seen at a distance. It was impracticable to draw all the 
birds to the same scale but all those on the same page are so figured. 
Reference should always be made, however, to the measurements given 
at the beginning of each description. The figures are based on the 
male bird.
