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.
