Another painter of colorful birds, tho I am not sure he ever made it to the Hawaiian Islands, was STARK (WINTHROPSTARK) DAVIS.
Born in Boston in 1885, he later moved to Chicago, finally ending in California, where he worked for Disney Animations Studios in Los Angeles and Burbank. (One of our neighbors when I was a child also worked in these studios).
Stark Davis was known for vivid, precise and imaginative works (one could not have worked at Disney in those early years without imagination) of birds, and some feel because of his work as a commercial artist and illustrator, he was not recognized as the fine, imaginative and original painter he was.
He is considered an impressionist as well as modernist (Art Deco). In later years he moved north to Morro Bay, dying in 1950.
