slightly under 500 people were involved. The area from Lock and Dam 12 
at Bellevue, Iowa, to Keokuk was covered by both plane and cars. A 
careful comparison was made. Dr. De Decker flew the plane with Pete 
Petersen, Jr. doing the counting. Dr. L. H. Princen handled the data for 
the Illinois River. Sergei Postupalsky covered part of the Wisconsin 
River, included with totals for the Mississippi. Many groups participated— 
Fish and Wildlife people, game management, lockmasters, and plain bird 
watchers. Thanks to all of them!

This completes 12 years of study. The first two were somewhat limited 
in scope and did not cover as much of the southern section where more 
immatures are found. The percentages for those two years were adults 86 
and immatures 14. The average number of eagles seen was 286. For the 
period 1962 thru 1966 an average of 601 eagles were found—percentages, 
80 adults, 20 immatures. For the period 1967 thru 1971 an average of 745 
eagles were found—percentages, 72 adults, 28 immatures. Golden Eagles 
as follows: 1 immature at Davenport; one in Union County and one at St. 
Louis; 2 adults in Kentucky.
