last year but not this year. JoDaviess County was the only AREA 4 
county without participants. 
A total of 31 counties reported 100 or more species this year with 
Cook again producing the high total, 163. TABLE 1 shows the record 
number of 19 counties with 20 or more observers; however, in some in- 
stances several counties were represented by members of single organi- 
zations—which was more beneficial. In 13 counties there were only one 
or two observers. 
At least 33 species were reported from 69 (90%) of more of the 
counties participating (TABLE 2). Only 11 species were found in all 
77 counties; however, several more species would have been included 
from all county reports if the criteria of 8 hours minimum observation 
time was adopted. In contrast, 18 species were acknowledged for a single 
county and 12 for only two counties. FIGURE 1 indicates the total 
number of species for each participating county, with the number of 
observers and party-hours in parentheses. Counties shown by cross- 
hatching were those without participants in 1974; the greatest voids 
continue to occur in the counties just below Springfield and in south- 
eastern Illinois. 
TABLE 3 shows the species observed, the number of counties re- 
porting each species, the total number of individuals of each species re- 
ported, and the county reporting the highest number of individuals of 
each species (with that highest total in parenthesis). At least 56 of the 
77 counties were responsible for reporting the high individual total for 
one or more species; TABLE 4 shows the 16 counties which reported the 
high totals for five or more species. 
The five most common species were again the same as the past two 
years. All three of the unprotected species (Rock Dove, Starling and 
House Sparrow) were in the top twelve. Our state bird ranked tenth 
both this year and last year. The order of reported abundance of the 20
