The most famous illustrations of the Cerulean Warbler are those of the French-born ornithologist and painter John James Audubon because of their great beauty, level of detail and accuracy in recreating the movement and habits of birds in their natural habitats; in this he was unsurpassed and was admired by great ornithologists and naturalists of his time.
His greatest work was The Birds of North America (1827), where, inspired by Wilson's work, he illustrates and describes - with his particular style - the birds of the United States.
Audubon describes other aspects of the natural history of the CERW as the shape of the nest and the materials with which it was built, parental care, clutch size, and plumage of the immatures (Audubon, 1841).
