20 ILLINOIS AUDUBON BULLETIN 
As could be expected, those counts reporting Bald Eagles all include 
large rivers or lakes within their count areas. Adams, Alexander, Carroll 
& Whiteside, Jersey—Elsah, Mercer—West, Rock Island, Rock Island & 
Mercer, Rock Island & Whiteside and Union all border the Mississippi 
River; Bureau & Putnam, Cass & Mason, Fulton & Mason and Marshall 
all include the Illinois River; Jersey & Calhoun includes both the 
Mississippi and the Illinois; and Williamson includes Crab Orchard 
Lake. Fifteen counts reported eagles, compared with twelve last year. 
More significantly, 596 Bald Eagles were reported this year, compared 
with 256 last year. (Last year the Jersey and Calhoun count wasn't 
reported to I.A.S.. American Birds reports 76 on that count last year, 
giving a total of 332 for Llinois for 1974.) Of this year’s 596, there were 
304 adults, 182 immatures, and 110 unspecified, as shown below:
