Second year male and adult female. Audubon originally called this bird the Stanley Hawk after Lord Stanley (Edward Smith Stanley, 13th Earl of Derby, 1775-c.1852). The bird was named after William Cooper (1798–1864), a conchologist and one of the founders of the New York Lyceum of Natural History, by Charles Lucien Bonaparte in 1828.
