The Birds Of Colorado Classic Reprint . Excerpt from The Birds of Colorado The following paper is designed to set forth our present knowledge of the distribution and migration of Colorado birds. There is also included a bibliography of the subject and an historical review of the progress of ornithological investigation in this State. The total number of species and varieties of birds known to occur in Colorado is 360, of which 328 are known to breed. This is a larger number of species than has been taken in any state east of the Mississippi and is exceeded by only one state of the Union, that is by Nebraska with nearly four hundred species. The reason for this great variety of bird life is found in the geographical position of the State and the physical characteristics of its surface. From the Atlantic Ocean to western Iowa but slight changes occur in the avi-fauna. But with the decreased rainfall and the increase in altitude from there westward, a great number of new forms appear. The greatest change is at the eastern foothills of the Rocky Mountains, which is the natural dividing line between the eastern and middle provinces of the United States. But while many of the western forms extend as stragglers eastward into Kansas and Nebraska and especially into the Black Hills of South Dakota and northwestern Nebraska, a large number of eastern forms do not pass west of the semi-arid region of twenty inches of annual rainfall and are not found in Colorado. It is due to this fact that Nebraska exceeds Colorado in the number of species taken in the State. All of the eastern species reach Nebraska and nearly all the western forms extend into northwestern Nebraska. This is strikingly shown in the case of the Warblers. Nebraska has more than twenty Warblers that do not occur in Colorado, while Colorado has less than five that are not found in Nebraska. The avi-fauna of Colorado is reinforced by species that belong more properly to the regions on all sides of it.

The Birds Of America. This groundbreaking work consists of hand-colored, life-size prints, made from engraved plates measuring around 39 by 26 inches (99 by 66 cm). This is the first of seven volumes. Audubon identified 25 new species over his career and is known for portraying animals in their real-life habitats. In contrast to other wildlife artists of his day, Audubon painted animals as if caught in motion—particularly feeding, hunting or escaping predators. The seven-volume Birds of America includes images of six now-extinct birds: the Carolina parakeet, passenger pigeon, Labrador duck, great auk, Esquimaux curlew and pinnated grouse. Nearly all later ornithological works were inspired by Audubon's artistry and high standards, and Birds of America is considered one of the greatest examples of book art. Numerous parks, towns and other places are named in his honor.
