The biggest factor causing changes in the statistics as presented in 
this report and those submitted by the compilers was incorrect addition; 
however, in some instances, certain species reported were not properly 
substantiated. As in past years, all unusual observations were to be 
documented. All documentation forms submitted were acknowledged to 
the compiler. Inexperience was the primary reason for reports of unac- 
cepted species. 
Participants desiring a complete copy of the Third Statewide Spring 
Bird Count Report should request one from the author. This report 
includes the total county results, the relative abundance of every species 
for each of the four AREAS and the complete list of observers. 
Northern [llinoisians, already dominating the count, will definitely 
have the advantage the next few years. Many wished that this count had 
been May 11th this year because an excellent wave of migrants had 
arrived. (They must have missed the wave of three days earlier). Any- 
way, next year the count is scheduled for Saturday May 10, 1975, the 
latest we will ever have it. 
At this time, I wish to thank everyone who helped with the count. 
Without your help, the count would not have been so successful and the 
many records would not have been established. Only with your con- 
tinued personal commitments will we be able to accumulate the data and 
knowledge about our birdlife which can be used for the benefit of pre- 
serving these wild populations. Special gratitude is expressed to the coun- 
ty compilers for their continued support and to Dorothy Bass who pains- 
takingly typed the report. We look forward to your help again in 1975.
