The Crossley ID Guide: Eastern Birds makes bird identification much easier.  Richard Crossley has used over 10,000 of his own photographs to make composite images for over 660 species found in the USA and Canada.  The plates show the birds in natural surroundings as one is likely to find them in the field, from various angles - perched, flying past, close up and afar. The images include male, females, juvis, adults and show their plumage changes over the seasons.  

This is a new approach to bird identification.  In pages 22-27 Crossley explains how the book should be used. Bird Topography is covered in pages 28 - 31 and the book starts with a visual size guide to help the reader understand the proportions of the birds in relation to each other. 
 

A lover of pictures, the author states he doesn't like text and prefers to use vibrant, colourful images to help train the brain to recognise the different shapes of the birds in their most likely to be seen  scenarios.
