We monitored breeding bird populations in a woodland plot in Hamilton County, OH. By comparing historical data (1991-1998) with 2003 populations, we observed a decrease in the populations of more species than expected by chance. In contrast, few species showed a population increase. Overall, the total number of territorial males in 2003 was 12% below the average number from 1991 to 1998.
