"A Synopsis of the Birds of North America" by John James Audubon is a catalog of North American birds created in the 1800s. It works as a guide, offering descriptions and classifications for those wanting to learn about the different types of bird species on the continent. Audubon explains why he made this organized list, pointing out that there needs to be a guide for his earlier works. He talks about how he plans to classify the many species from Mexico to the Arctic, and how important it is to have easy nomenclature for readers, and thanks Mr. Macgillivray in the introduction.

Summary
About the AuthorJohn James Audubon was a French-American self-trained artist, naturalist, and ornithologist. His combined interests in art and ornithology turned into a plan to make a complete pictorial record of all the bird species of North America. He was notable for his extensive studies documenting all types of American birds and for his detailed illustrations, which depicted the birds in their natural habitats. His major work, a color-plate book titled The Birds of America (1827–1839), is considered one of the finest ornithological works ever completed. Audubon is also known for identifying 25 new species. He is the eponym of the National Audubon Society, and his name adorns a large number of towns, neighborhoods, and streets across the United States. Dozens of scientific names first published by Audubon are still in use by the scientific community. In recent years his legacy has become controversial for his involvement in slavery and his racist writings as well as allegations of dishonesty.
