NEW YORK (AP) -- Artist and naturalist Roger Tory Peterson has been called "the Audubon of the 20th century" for his Field Guides to birding.
Next month, bird lovers will have the chance to buy original paintings and photographs that were used to illustrate his system of bird identification.
His estate is offering hundreds of items on Sept. 8 through Guernsey's Auctioneers in New York City.
Peterson died in 1996. The naturalist spent a lifetime watching, painting and photographing birds in the wild, drawing comparisons to the 19th century ornithologist John James Audubon.
Peterson's Field Guide series set the standard for the modern nature guide.
The Roger Tory Peterson Institute of Natural History in Jamestown, N.Y., created in 1986 to house his body of work, hopes some buyers will donate their purchases.
