Abstract
We studied eastern towhees at the Savannah River Site, a species of concern and in decline. Breeding season survival rates, nest success rates, breeding densities and daily movements were compared between mature longleaf savanna areas and recently harvested and regenerated areas. Survival rates did not vary by sex or stand type. Predation levels were very high. Abundances were lower in mature longleaf than recently regenerated areas.
