Wildlife importation into the United States, 1900-1972
U.S. Dept. of the Interior, Fish and Wildlife Service, 1976 - Nature - 18 pages
Data from Bureau of Biological Survey and U.S. Fish and Wildlife Service reports show an overall increase in the number of birds and mammals imported from 1900 to 1972. The trend ws interrupted by World War I, the economic depression of the 1930's, and World War II. data are lacking for years after World War II until 1968. Until 1942, domesticated canaries and a few species of game birds made up most of the avian imports; the shell parakeet or budgerigar was the most commonly imported parrot. Although the number of birds imported 1968-1972 was not greatly different from the pre-depression years, the proportion of canaries, game species, and parakeets declined greatly and the variety and number cage birds including other parrot species greatly increased.
