We analyzed a three-year consolidated sample of Louisiana hunters’ responses to the Louisiana Game Harvest Surveys (LAGHS) distributed via email and mail in May following the 2016–2017, 2017–2018, and 2018–2019 hunting seasons. To determine whether the distribution modes pro- duced different results, both modes asked identical questions about hunting effort, harvest, and age. We used generalized linear mixed models to test hypotheses about hunters’ days hunted, harvest, representation of age classes, and effect of age-weighting (i.e., weighting responses based on the differ- ence in...

Wild pig (Sus scrofa) populations have exploded across much of the southeastern United States. In order to combat increasing wild pig num- bers in an effort to reduce both ecological and economic damage caused by wild pigs, toxicant baits are being investigated as a possible method to reduce wild pig numbers at the local scale. In fall 2017, we tested the HogStopper? feeder to ascertain if this feeder design would deliver bait to wild pigs while preventing non-target species from accessing bait. We examined visitation rates at feeders for wild pigs and non-target species using both digital...

Concentrating hunters on dove fields could place mourning doves (Zenaida macroura) and other ground foraging birds at risk of lead poisoning. We collected soil samples during three time periods (pre-soil disturbance [i.e., disking], post-soil disturbance [disking, roller harrow, planting], and post-hunting / field preparation [i.e., mowing, raking, burning]) to determine if soil disturbance reduced the amount of lead shot potentially available to ground foraging birds in managed dove fields. We also collected soil samples in the woods adjacent to these fields. Disking and site preparation...

Long-term declines in American woodcock (Scolopax minor) populations may be partially the result of low survival rates on wintering grounds especially in nocturnal habitats. We compared microhabitat characteristics of woodcock nocturnal roost sites to random sites in eastern Texas. We located woodcock roost points by nightlighting in winters of 2000-01 (45 points) and 2001-02 (74 points). Percentage bare soil, sapling-size tree canopy cover above 0.5 m, and sapling density were greater at roost than random sites. Conversely, shrub ground cover (i.e., below 0.5 m) was lower at roost than...
