Collection of 190 pictures of birds in watercolor, pen, and pencil, by several artists, as well as 2 title pages, board, and spine. Includes birds found in Australia, India, and New Guinea.

Preparatory manuscript artwork and separate lithographic prints for the bird books created by John Gould and the artists employed in his publication workshop in London, England, in the 19th century. Birds found in these books exist around the world, including in North and South America, Asia, Australia, the United Kingdom and continental Europe, the Himalayan mountains, New Guinea, and Papua.

This collection consists of two watercolor paintings of birds, signed and dated 1952 and 1954 by Robert M. Mengel (1921-1990). The 1952 painting has a label identifying it as a ”Black-and-white warbler at nest," and the other watercolor is of an owl.
