Gilliland, J. Richard. 1969. Summer Bird Watching At Wind Cave National Park. South Dakota Bird Notes, Official Publication of the South Dakota Ornithologists' Union (Organized 1949) XII. pp. 53-60.
This is a short article on bird watching at Wind Cave National Park followed by a list of 93 species of birds observed by the author during the summers of 1967 and 1968 as a seasonal naturalist at the Park. About 45 bird hikes were taken; each hike averaged and hour and a half in duration. All three avifaunal habitats were visited at least 10 times during the two-summer period. Pettingill's and Whitney's Birds of the Black Hills served as a general reference and is the source of subspecies where they are listed (Pettingill and Whitney, 1965). The listings and nomenclature are those used in the American Ornithologists' Union Check-list of North American Birds, Fifth Edition, 1957.
