Table 1 Parameter estimates (β; logit scale) for models examining how fire characteristics affect female eastern wild turkeys (Meleagris gallopavo silvestris) distribution of use and behaviors (i.e., foraging, loafing, and walking) within recently burned (i.e., ≤250 days post burn) areas. Standard errors (SE), Z values, and probabilities that a coefficient differs from 0 are also presented. Data were collected from GPS-tagged wild turkeys at Silver Lake Wildlife Management Area in Georgia, Webb Center Complex in South Carolina, and Kisatchie National Forest in Louisiana, USA, between 1 March and 31 July, from 2014 to 2017

  1. aVariables are scaled to aid model convergence. Distance to unburned stand was divided by 100, time-since-fire (days) was divided by 50, and burn heterogeneity was multiplied by 100. Parameter estimate on logit scale
  2. bTurkey ID was considered to be a random effect in the model. Thus, it is an estimate of standard deviation of the random effect term
