THE 1942 STATUS OF WILD TURKEYS IN MISSOURI 429
the initial inventory showed 23 flocks totaling
142 birds, the much more careful second survey
disclosed 26 flocks totaling 165 birds. This indicates an accuracy of 86 per cent in the first coverage, and is probably typical of the whole inventory. Since the figures which follow are based on the actual field data, they are undoubtedly conservative.
PRESENT TURKEY POPULATION
Table 1 compares the turkey population by counties in 1942 with that estimated by Bennitt and Nagel (I) in the winter of 1934-35. The
present total of 4,340 birds shows approximately a 20 per cent increase over the 1935 figure of 3,585 birds. In terms of density, Leopold in 1931 (7) estimated an average density of 1.4 square miles per turkey, Bennitt and Nagel 2.8 square miles per bird over 9,907 square miles, and the present inventory 1.6 square miles per bird over approximately 7,000 square miles.
Originally the turkey range covered the entire state. Turkeys were apparently still abundant in parts of the northern counties until long after their settlement, as indicated by the report of Bogardus (3) that he and two others killed over 50 in three weeks on Shoal Creek in Clinton County, northwestern Missouri, in 1866. In northeastern Missouri there were turkeys in a few favored localities until 1895 and in one locality in Macon County until 1908. The last deer, on the other hand, disappeared from north-eastern Missouri by 1882, 25 years before the last turkey. By about 1910, the turkey range had been reduced to the Ozark region and the southeastern lowlands, and in 1935 turkeys were found in only 45 of the 114 counties of the state. Today only 31 counties are known to contain turkeys, and of these only 17 contain more than 6 flocks each, although the total number of birds has increased slightly. It has taken a little less than 100 years to eliminate the turkey over 83 per cent of its original range in Missouri.
The present occupied range amounts to approximately 7,000 square miles in the Ozark region. Only one small remnant can now be found in the southeastern lowlands, and the encroachment of settlement and agriculture may ultimately eliminate the species from that region, thus further reducing the range.
Figure 1 shows the present locations of all flocks and their relative sizes. The 596 flocks recorded show the following distribution by size classes:
