Birds and Trees of North America is Rex Brasher's seminal work, comprised of 874 watercolor paintings bound in an encyclopedic set. Between 1929 and 1932, he created 100 twelve-volume sets—1,200 individual books—and sent them to patrons across North America. Volume 4 contains 76 birds, including rails, gallinules, coots, phalaropes, snipes, plovers, turnstones, oystercatchers, and jacanas.
