Wood engraving continued to be used for bird book illustration late into the 19th
century. Even after lithography took the place of metal engraving for bird art, wood
engravings proved most effective for clear reproduction of anatomical detail. Many books
which were chiefly illustrated by lithographic plates also contained wood engravings as
additional descriptive material, some colored, and some not.
The colorful engraving shown here is believed to be the work of Edwin Sheppard.
