habitat selection

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...

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...

Reclaimed surface mines present an opportunity to provide large tracts of habitat for northern bobwhite (Colinus virginianus). Reclaimed surface mine sites are commonly planted to non-native species, including sericea lespedeza (Lespedeza cuneata) and tall fescue (Schedonorus arundinaceus), which can inhibit growth of more desirable plant species and limit favorable structure for bobwhite. There have been no studies documenting how bobwhites use various vegetation types common to reclaimed surface mine land. Habitat use studies can provide information on selected vegetation types on these...

Mottled ducks (Anas fulvigula) are endemic to Gulf Coastal United States, Florida, and Mexico. Birds from Florida, Louisiana, and Texas were released in coastal South Carolina from 1975 - 1983, and subsequent banding data suggest a dispersing and increasing population in the state. Because autecology of mottled ducks is little known in South Carolina, we radio-marked 116 females in August 2010 - 2011 in the Ashepoo, Combahee, and Edisto Rivers Basin to assess habitat use throughout the annual cycle. We monitored habitat use by aircraft during fall-winter and via ground reconnaissance...
