| Abstract: | 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 was interrupted by World War I, the economic depression of the 1930‘s, and World War II. Data are lacking for the 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 total number ofbirds imported 1968-72 was-not greatly different from the pre-depression years, the proportion of canaries, game species, and parakeets declined greatly and the variety and number of cage birds including other parrot species greatly increased. Until 1930 most mammals imported were for laboratory use or fur farming. After 1930 the number of imported mammals increased with the growing importance of primates, especially rhesus macaques, in research. Since 1968 the number of mammals irnported annually has been at least 5 times greater than the previous peak of 1938, and primates have made up 87% of mammalian imports. Information on reptiles and amphibians imported into the United States is available only for 1970 and 1971. Turtles were the most commonly imported reptiles, frogs and toads the most commonly imported amphibians. |
