Influence Of Northern Bobwhite Nest Site Selection On Nest Survival In An Agricultural Landscape, Andy D. Richardson, Christopher E. Moorman, Craig Harper, Mark D. Jones, Benjy M. Strope

National Quail Symposium Proceedings

Working farms provide excellent potential for conserving northern bobwhite (Colinus virginianus) habitat in agricultural landscapes. Managing for areas of early successional vegetation can increase bobwhite abundance with little reduction in crop production on working farms, but the mechanisms behind the increase is not well known. Our objective was to determine nest site characteristics that may predict nest initiation and survival on agricultural lands to inform future management activities. We radio-collared 241 wild bobwhite on 1 farm with and 2 farms without bobwhite habitat management in southeastern North Carolina. Study sites consisted of a 1,740-ha farm with 9% of …


Response Of Grassland Birds To Agricultural Intensity At Different Spatial Scales In Texas, Anna Matthews, M. Clay Green, James Giocomo Nov 2017

Response Of Grassland Birds To Agricultural Intensity At Different Spatial Scales In Texas, Anna Matthews, M. Clay Green, James Giocomo

National Quail Symposium Proceedings

The decline in grassland birds is often associated with habitat loss due to intensity of conversion to agricultural lands and the alterations of natural disturbances. We sought to identify agricultural effects at differing scales that correlate to Texas grassland bird abundance, especially northern bobwhite (Colinus virginianus). Ninety-five roadside routes were surveyed in 20 Texas counties ranging from the Oklahoma border to the coastal plains. We conducted point counts in May and June from 2013 to 2016. To estimate the coarse effects of agriculture on bird abundance at a county level, we used number of cattle and area of …
