The John James Audubon Center at Mill Grove : [...] "The Viviparous Quadrupeds of North America" [is] Audubon's second monumental project. With the publication of “The Birds of America” earning John James Audubon worldwide fame he became interested in his next large-scale project. In the early 1840’s he began working on “The Viviparous Quadrupeds Of North America” with the help of his son John Woodhouse Audubon. They would produce 150 folio drawings, measuring approximately 22x28 inches, hand-printed and hand colored by J.T. Bowen of Philadelphia. Each print is dated with many later plates being credited to John Woodhouse Audubon as his father’s health declined. The prints are dated 1845 – 1848.

The mountain goat or Rocky Mountain goat (Oreamnos americanus) is a hoofed mammal endemic to mountainous areas of western North America. A subalpine to alpine species, it is a sure-footed climber commonly seen on cliffs and ice. The mountain goat is an even-toed ungulate of the family Bovidae (along with antelopes, gazelles, and cattle) and the subfamily Caprinae (along with true goats, wild sheep, the chamois, the muskox and other species). Oreamnos americanus is closely allied with the takins (Budorcas) and chamois (Rupicapra).
