  <dc:description>Rural mail-carrier sightings of red foxes (Vulpes vulpes) during mid-April, -July, and -September of 1969-73 were compared to spring fox family estimates derived by aerial searches of six townships. The mid-April mail-carrier index reflected annual fox density changes on the six townships (correlation coefficient = 0.958) . Random exclusions of individual mail-carrier reports indicated participation could decline 40 percent without affecting index accuracy.</dc:description>
