Although he never had had any formal scientific training in zoology, Ramsay had a keen interest in natural history and published many papers. In 1863 he was treasurer of the Entomological Society of New South Wales, he contributed a paper on the "Oology of Australia" to the Philosophical Society in July 1865, and when this society was merged into the Royal Society of New South Wales, he was made a life member in recognition of the work he had done for the Philosophical Society.
In 1868 Ramsay joined with his brothers in a sugar-growing plantation in Queensland which, however, was not successful. Ramsay was one of the foundation members of the Linnean Society of New South Wales when it was formed in 1874, and a member of its council from the beginning until 1892. He became the first Australian-born Curator of the Australian Museum,[2] and built up a large variety of native weapons, dresses, utensils and ornaments illustrating the ethnology of Polynesia and Australia. From 1876 until 1894, when he had to resign due to his declining health, he published a Catalogue of the Australian Birds in the Australian Museum at Sydney in four parts.
In 1883 Ramsay traveled to London to attend the International Fisheries Exhibition. At that time he met Military Surgeon Francis Day who had collected fishes over several decades in India, Burma, Malaysia and other areas in southern Asia. Ramsay negotiated purchase a portion of Day's collection, including about 150 of Day's type specimens.
After his resignation as Curator, Ramsay served the Australian Museum as "consulting ornithologist" until 1909. He died on 16 December 1916 because of carcinoma.
