Book Description
State reports covering the propagation and trial liberation of foreign game birds are summarized from the period 1960 through 1963. Details are then provided in tabular form. Of the 21 species and subspecies and 6 crosses reported, only the sandgrouse and the Himalayan snowcock have not yet been produced in numbers in captivity. Increasing consideration is being given to the production of well-reared birds conditioned for survival in the wild following release. In all 78,217 individuals, mostly pheasants, are reported to have been raised for trial liberation from breeders provided through the Foreign Game Introduction Program. These releases supplement 16,145 birds wild-trapped and sent to cooperating States for trial release. While, for most species under trial, it is still too early to evaluate results, some are evident. Iranian pheasants, black francolin and gray francolin have demonstrated the ability to survive, reproduce and increase substantially on release areas. Conversely, Indian sandgrouse and two other species have probably failed to adapt themselves and the semi-domestic strain of Reeve's pheasant is barely hanging on. Six other species are maintaining themselves in numbers sufficient to justify guarded optimism.

Book Description
The Density Index of breeding doves declined in each management unit between 1967 and 1968 at the following rate: Eastern, 4 percent ; Central, 2 percent ; Western, 13 percent ; and the entire contiguous United States, 5 percent. Regression analyses suggest that the trend in populations has been downward in all units since 1958. Although biased to an unknown degree, data collected in conjunction with the Annual Waterfowl Mail Questionnaire Survey suggest that the harvest in the United States increased 28.9 percent and that dove hunters (who also purchased duck stamps) increased 31.5 percent during the period 1965-1966 through 1967-1968. The increase in harvest was due chiefly to an increase in hunter numbers.

Book Description
Groups of data are organized by flyways, from Pacific to Atlantic, with appendixes of tables to correspond. Individuals or organizations that submitted a report have been credited. Although many of the narrative statements have been briefed, and a few tables deleted or shortened if they contained data submitted previously or in another form, the essential information from each report has been retained to the greatest extent possible.
