During the final two years of production of The Birds of America, Audubon accelerated his schedule by combining species in certain plates. A case in point is this watercolor model with five warblers—one named after William MacGillivray, editor of Audubon’s Ornithological Biography and his good friend. He also frequently painted western species from specimens obtained from Townsend and Nuttall. Completing the watercolor in Charleston, Audubon instructed Havell to divide the birds between plates 399 (Figure 1) and 414 (Figure 2). Even though he included a number of species in the same vignette he arranged them in such a manner as to convince us that they were interacting and at any moment could fly off the page to perch in some other branch.
