SHORT COMMUNICATIONS

the effects of urbanization on avian parasites may 
identify mechanisms by which urbanization affects 
survival and demographics of some raptor species. 
ACKNOWLEDGMENTS 
We thank Sara Johnson Miller and Sandra Stone for 
assistance with fieldwork, and T. L. Whitworth and Greg 
Dahlcra for assistance with identification of blow flies. We 
also thank the many landowners of the Cincinnati and 
Hocking Hills regions who allowed us access to their 
private property to conduct this research. This work was 
supported by grants from RAPTOR Inc. and Marilyn Arn. 
T. L. Whitworth and two anonymous referees kindly 
reviewed an earlier version of this manuscript.
