My library job seldom requires me to visit those sections of the building where science books live, but there is no part of the library that I don't end up poking through occasionally in the course of resolving some puzzle or other. That is how I chanced upon Baby Bird Portraits, published in 1998 by the University of Oklahoma Press (and still in print).
George Miksch Sutton (1898-1982) was a professor of ornithology with a special talent for painting the birds he studied. He worked in the American Midwest for most of his long career. The reproductions shown here are samples from a collection of his watercolors in the library of the Field Museum in Chicago. They depict "a variety of downy nonpasserine chicks and nestlings."
