Nesting Activity and Nest Site Characteristics of a Translocated Eastern Wild Turkey Population in East Texas

SEAFWA Journal Volume 7, March 2020

Sustainability of eastern wild turkey (Meleagris gallopavo silvestris, hereafter turkey) populations following translocation is dependent on reproductive success. Extensive efforts to restore turkeys to east Texas using translocation have yielded mixed results, leading to low-density, fragmented populations. Dynamics of a translocated turkey population are dependent on the outcome of nesting activity and nest success which can be influenced by vegetative characteristics selected by females when nesting. Because translocated turkeys transition from natal to new habitats, understanding...

Evaluating Reproductive Parameters of Rio Grande Wild Turkeys to Guide Policy Decisions in Texas

SEAFWA Journal Volume 7, March 2020

Historically, Rio Grande wild turkeys (Meleagris gallopavo intermedia) in south central Texas have been at lower densities than in other por-tions of the state. Within the Oak-Prairie Wildlife District of Texas, Rio Grande wild turkey regulatory restrictions are different for counties in the east- ern and western portions of the region. Due to perceived increases in turkey density in the eastern portion of the ecoregion, Texas Parks and Wildlife Department (TPWD) considered increasing the bag limit in the Rio Grande wild turkey spring-only 1-bird zone counties to increase hunting oppor-...

Eastern Wild Turkey Response to Hunting Feral Hogs with Dogs

SEAFWA Journal Volume 7, March 2020

Impacts of feral hogs (Sus scrofa) on native plant and animal communities have increased as feral hogs have expanded in geographic range. Wildlife managers use a host of tactics to manage population growth of feral hogs, including recreational hunting with dogs. However, hunting with dogs can cause disturbance and behavioral changes to non-target species. We monitored 161 eastern wild turkeys (Meleagris gallopavo silvestris) over 147 days during 2014-2018 in South Carolina to evaluate turkey movement behaviors and range sizes before, during, and after spring feral hog-dog hunts. The...

Behavioral Responses of Female White-tailed Deer to Small Game Hunting Activities

SEAFWA Journal Volume 7, March 2020

Environmental and anthropogenic stimuli can impact a variety of species' behavioral ecology. White-tailed deer (Odocoileus virginianus) re- spond both spatially and temporally to various types of disturbance; however, our understanding of how disturbance impacts deer behavior is typically regulated to studies where white-tailed deer are the targeted species. We used GPS data collected from female white-tailed deer (n=10) to evaluate space use in response to small game hunting activities based on whether an individual was within the hunted area (actively disturbed) or outside (passively...

Survival and Distribution of Black-bellied Whistling-duck (Dendrocygna autumnalis) in the Southeastern United States

SEAFWA Journal Volume 6, March 2019

Black-bellied whistling-duck (Dendrocygna autumnalis; BBWD) is a neo-tropical species distributed in coastal areas of northern South Amer- ica, Central America, and southern North America. Despite their pervasiveness, the population distribution, survival, and harvest-mortality of BBWD in the southeastern United States remains unclear. We used BBWD sightings reported to eBird to delineate range expansion from 2006–2016 in Ala- bama, Florida, Georgia, Louisiana, Mississippi, South Carolina, and Texas. Concurrently, we used band-recovery data from 759 BBWD captured in five states (Georgia,...

Impact of Supplemental Feeding for Northern Bobwhite on Movement Ecology of Eastern Wild Turkeys in South Carolina

SEAFWA Journal Volume 5, March 2018

Management techniques to improve wildlife populations often can affect non-target species indirectly. Supplemental feeding for northern bobwhite (Colinus virginianus) has become a popular management technique to improve bobwhite recruitment and survival, but potential impacts on non-target species such as eastern wild turkey (Meleagris gallopavo silvestris) are unknown. We deployed 111 global positioning systems on wild turkeys on the South Carolina Department of Natural Resources Webb Wildlife Management Area Complex during 2014-2016 to evaluate if supplemental feeding for quail impacted...

Apparent Survival of White-tailed Deer in the Mississippi River Delta of Louisiana

SEAFWA Journal Volume 5, March 2018

White-tailed deer (Odocoileus virginianus) populations located at the mouth of the Mississippi River are of historical significance as they have been a major source for restocking in Louisiana since the 1960s. Apparent population declines of these deer since the 1990s led the Louisiana Department of Wildlife and Fisheries to initiate a study to gather demographic data on white-tailed deer on the 46,540-ha Pass-a-Loutre Wildlife Management Area (PALWMA). We captured and individually marked 57 deer on PALWMA from 2007 to 2012. We monitored travel corridors using un-baited trail cameras and...

Movements and Habitat Selection of Male Rio Grande Wild Turkeys during Drought in South Texas

SEAFWA Journal Volume 4, March 2017

Wildlife managers rely on accurate information regarding wild turkey habitat selection and use to appropriately structure management activities. We used integrated VHF-GPS transmitters to evaluate fine scale movements and habitat selection of male Rio Grande wild turkeys (Meleagris gal- lapavo intermedia) in south Texas. As our study coincided with the regions second worst recorded drought, we evaluated the influence of supplemental resources (supplemental feeding and managed surface water) on turkey distribution and movements. We deployed eight GPS units on adult male Rio Grande wild...

Hunting Activity and Male Wild Turkey Movements in South Carolina

SEAFWA Journal Volume 4, March 2017

Anthropogenic pressure can have significant impacts on how wildlife move and how they use habitats. During 2014-2016, we deployed 41 GPS transmitters on male wild turkeys on the South Carolina Department of Natural Resources Webb Wildlife Management Area (WMA) Complex to evaluate effects of hunting intensity on male wild turkey movement ecology. Daily mean movement distance was 3,254 m day-1, but there was significant variation in our mean estimate (SD = 1,478) with movements ranging from 137 to 14,599 m on any given day. Male wild turkeys slightly decreased their movements in response to...

Assessment of GPS Transmitters for Use on Northern Bobwhite Quail

SEAFWA Journal Volume 4, March 2017

Technological advances allow researchers to increase the quality and quantity of spatial information gathered for movement ecology and range estimation. We conducted a field experiment to assess accuracy of PinPoint GPS transmitters for use on small avian species using northern bobwhite quail (Colinus virginianus) as our test species. We conducted a series of static tests to evaluate relative impacts of canopy cover across a suite of data collection schedules. We also evaluated GPS units on 6 wild northern bobwhite quail trapped in north-central Texas. Radial error estimates from static...
