Differential seasonal avoidance of anthropogenic features and woody vegetation by Lesser Prairie-chickens

The influence of seasonal variation in animal behavior and the corresponding response in habitat selection is a critical component of habitat selection analyses. To examine this relationship, we conducted multi-scale analyses of Lesser Prairie-chicken (Tympanuchus pallidicinctus) habitat selection in relation to anthropogenic infrastructure associated with oil and gas development, mesquite, and trees during the spring and summer at home range and lek area scales. We tracked 159 Lesser Prairie-chickens using VHF radiotelemetry or PTT-GPS transmitters in the sand shinnery oak prairie region of eastern New Mexico, USA. We used discrete choice models and logistic regression to assess seasonal patterns of habitat selection at home range and lek area scales, respectively. The static habitat features we examined allowed us to observe differential patterns of habitat selection between the two seasons, revealing an overall increase in the degree of avoidance following the spring season.
