collected from agricultural fields and from crops of hens on three areas--good 
pheasant range (Ford and Livingston counties), fair range (northern Coles County), and 
poor range (Neoga release area in Cumberland County)--and chemically analyzed. The 
collections were made during October 1S 66 and January J 367 . Corn from fields was 
collected at 12 locations on each area; corn from crops was removed from 16, 11 , and 
II hens, respectively, from the three areas. The samples were pooled according to 
area and whether they were from fields or from pheasants. The analyses were conducted 
by the same procedures and for the same elements described in the report for June 1967 
(Monthly Wildlife Research Letter 10(6);1-2). 
Surprisingly, more differences were found between corn from fields and corn from 
pheasants (from the same area) than among corn (from either fields or pheasants) from 
the three areas. The percent ash of corn from fields was 1.33, 147, and 1-37, on a 
dry-weight basis, for good, fair, and poor pheasant range, respectively. As a 
comparison, corn from pheasants from the three areas was l.70, 1 . 62 , and 1.85 percent 
ash. Sodium was found to be strikingly more abundant in corn from pheasants (160, 
12 C, and 208 ppm, on a dry-weight basis) than in corn from fields (l, G, and 16 ppm). 
Calcium exhibited similar trends, being 137, 165, and 114 ppm in corn from pheasants 
but only II, 51, and 25 ppm in corn from fields. Ten trace elements (aluminum, 
chromium, cobalt, iron, manganese, nickel, strontium, titanium, vanadium, and 
zirconium) were also consistently more abundant in corn from pheasants than in corn 
from fields. Only one element, molybdenum, was consistently more abundant in corn 
from fields (1.12, 0.27, and 0.45 ppm) than in corn from pheasants (0.05, 0.01, and 
0.09 ppm). These findings tentatively suggest that not only pheasants in good range, 
but pheasants in fair and in poor range, also, are capable of selecting corn contain¬ 
ing greater than average concentrations of minerals. 
4. Responses of Bobwhites to Habitat Manipulation J. A. Ellis, K. P. Thomas 
highlighting on the experimental management zone on the Forbes Area indicated 
significantly higher quail populations in this zone in l 967 than in 1366. Totals of 
23-6 and 11 .S quail were observed per hour of nightlighting in 1967 and 1366 , re¬ 
spectively. This difference was statistically significant (£ 2 =30-9, P <0.005). 
Night-roosting cover in the experimental management zone in I 566 consisted of 
seven scattered, fallow plots of grasses and weeds; the sod age was at least 3 year-- 
In 1967, roosting cover consisted of seven scattered plots containing small-grain 
stubble. Wheat and oat stubble has been recognized as prime quaiI-roosting cover. 
Burning, and reestablishment of small grains, will be used to maintain adequate 
roosting cover in the experimental management zone on Forbes.
