Predator activity, proactive anti‐predator strategies and nesting phenology produce a dynamic landscape of risk to tundra goose reproduction

open access: yesJournal of Animal Ecology, Volume 94, Issue 11, Page 2282-2294, November 2025.
We show that Arctic and red fox space use significantly affects goose nest habitat selection and nest success in a low‐Arctic tundra ecosystem. However, the impact of fox predation depended on the location and timing of incubation of the nest, demonstrating the importance of incorporating time into the ‘landscape of fear’ concept.

Effects of broadcasting supplemental feed into roadside vegetation on home range and survival of female northern bobwhite

open access: yesWildlife Society Bulletin, 2015
Declines in northern bobwhite (Colinus virginianus) populations have led landowners in Texas, USA, to develop various management strategies to combat waning abundance.

Application of passive acoustic monitoring to compare avian populations in perennial grasslands and croplands in Nebraska

open access: yesEcological Solutions and Evidence, Volume 6, Issue 4, October–December 2025.
Using passive acoustic monitoring, researchers in Nebraska found that perennial grasslands support greater species richness of grassland obligates and at‐risk birds than croplands throughout most of the migration and breeding season. Abstract Perennial grasses, such as switchgrass (Panicum virgatum), have emerged as a promising and reliable feedstock ...

Factors affecting trapping success of northern bobwhites in the rolling plains of Texas

open access: yesWildlife Society Bulletin, 2016
Trapping of northern bobwhites (Colinus virginianus) is commonly conducted for research purposes. We investigated the influence of weather, lunar phase, time of day, and season on bobwhite trapping success in the Rolling Plains ecoregion of Texas, USA ...

Northern bobwhite autumn and winter food habits in restored pine–bluestem habitats

open access: yesWildlife Society Bulletin, 2016
We determined autumn and winter food habits of hunter‐harvested northern bobwhites (Colinus virginianus; n = 388) over 11 years (1998–2009) in a matrix of restored shortleaf pine–bluestem (Pinus echinata–Andropogon–Schizachyrium), and unthinned and ...

Two centuries of human‐mediated gene flow in northern bobwhites

open access: yesWildlife Society Bulletin, 2017
The northern bobwhite (Colinus virginianus; hereafter, bobwhite) population decline has prompted several studies over the past decade investigating bobwhite population genetics and overall connectivity. The zeitgeist of current quail conservation is that

Acute toxicity of gossypol in northern bobwhites

open access: yesJournal of Applied Animal Research, 2019
Gossypol, a secondary metabolite found in cotton (Gossypium spp.), is known to be toxic to a variety of animals, particularly monogastric mammals and commercial poultry (Gallus domesticus).

An evaluation of population indices for northern bobwhite

open access: yesWildlife Society Bulletin, 2019
Northern bobwhite (Colinus virginianus) populations are monitored using 2 general approaches—population indices and abundance estimators. Due to their convenient sampling designs, indices are commonly used by land managers and researchers to predict or ...

Exotic grass alters micro‐climate and mobility for northern bobwhite chicks

open access: yesWildlife Society Bulletin, 2015
Conservation practices are designed to provide habitat conditions that meet the environmental requirements for species of conservation concern. However, exotic invasive grass species may reduce the efficacy of these practices because they disrupt ...

Differences in foraging behavior in wild and pen‐raised northern bobwhites

open access: yesWildlife Society Bulletin, 2016
Increased mortality rates of northern bobwhites (Colinus virginianus) raised in captivity and stocked into the wild compared with wild bobwhites may be due to differences in antipredatory behaviors.
