					 A152 - Birds 
					   This is an especially important poster because it 
					presents the new Sibley-Ahlquist bird classification system. 
					Based on recent DNA studies, it uses cladistics to 
					reconstruct the evolutionary family tree, making the 
					traditional system obsolete. This new system has been widely 
					accepted by North American ornithologists.  
					This is a truly beautiful poster, one that will be greatly 
					appreciated by bird-lovers. It will certainly enhance the 
					decor of their home or office. It uses the same graphic 
					design as Mammals, making the two posters a matched 
					set. It presents information that has even greatest value. 
					It explores all the bird orders, introducing them by the 
					common name of the species, followed by the name of the 
					order. It explains all of the classification changes, 
					order-by-order. Representative species are shown and 
					identified by both common and scientific name. 
					This information has never before been published in such a 
					concise and convenient form, making this poster an essential 
					reference to anyone seriously interested in birds. 
					    
					Great care went into selecting the species that are shown. 
					The primary goal was to show representative species  from 
					each order. Within that context, we have tried to show North 
					American birds and other birds familiar to the reader. 
					Selected species include the American Bald Eagle, the 
					Canadian Goose, pet parakeet and cockatiel, robin, mallard 
					duck, roadrunner, turkey and pigeon.  A few of the 
					illustrations are shown below.  |
