All of the stunning paintings in Svenska Fåglar (Swedish Birds) by the von Wright brothers (1929 folio version) are in the public domain, and free to download and use in any way you wish. This is exquisite artwork, so even if you don’t want to use it, have a wander anyway, your day will be better for it. Also in the public domain are Birds of Australia, Ornithological volume by John Gould (1804-1881), illustrated by Elizabeth Gould (1804–1841), which introduced more than 300 new birds to the world.
