Abstract

Research on northern bobwhite calling behavior and roosting ecology during the breeding season has received limited attention. However, variability in calling rate in response to conspecifics and environmental factors may affect avian monitoring strategies. We conducted 10-minute breeding season surveys (April-August) on B. Bryan Farms, Mississippi, from 2021-2022 to evaluate the impact of conspecifics and environmental covariates on male bobwhite calling rate. We observed a positive linear effect of conspecifics and temperature on calling rate. We did not find sufficient evidence to support a relationship between calling rate and cloud cover or barometric pressure. We also analyzed breeding season third-order roost site selection and found selection against bare ground and a quadratic relationship with litter and average vegetation height during roosting activity. It is also important for managers to consider all conditions of the environment and habitat requirements during every season for population persistence, including breeding season roost cover.
