Abstract

This study examined the population biology of two syntopic soricids, Sorex cinereus (masked shrew) and S. fumeus (smoky shrew), in southwestern Pennsylvania. I used dry pitfalls as live-traps; two 1-ha areas were trapped (100 traps each) for three summers. Traps were opened for 6-8 h once a week and checked every 1.5 h. Fifty-six individual shrews were captured, marked, and released. More shrews were caught during the first summer. No individual was recaptured more than four times and only two individuals were recaptured between summers. Low capture rates were due both to inefficiency of the pitfall traps and to a real decline in density.
