Sir Frederick John Jackson was an English administrator, explorer and ornithologist. Jackson joined the British Ornithologists' Union in 1888. That year a paper by Jackson and Captain Shelley was published describing birds collected during his 1884-1886 trip to Africa. He collected many specimens in an 1898-1891 expedition to Uganda, and descriptions of this collection were published in a five-part paper in the Ibis in 1891-1892. Other papers described new species appeared in the Ibis and other journals between 1890 and 1917. Jackson was elected President of the East Africa and Uganda Natural History Society in 1910. He wrote nine of the nineteen chapters of Big Game Shooting, published in 1894. After retiring he worked on a complete history of the Birds of East Africa and Uganda, which was unpublished when he died in 1929, following pneumonia. The Birds of Kenya Colony and the Uganda Protectorate was completed by William Lutley Sclater
