Spencer Baird and John Cassin were contemporaries and friends, Baird at the Smithsonian and Cassis at the Academy of Natural Sciences.

Cassin, in particular, classified the birds collected on U.S. expeditions to many parts of the world. A thoroughly interesting work with a unique selection of maps and plates.
