Potential effects of neonicotinoid insecticides on northern bobwhites

Wildlife Society Bulletin, 2018
Northern bobwhite (Colinus virginianus) populations have been declining in Texas, USA, for nearly 3 decades. Reasons for the decline are unclear; however, a variety of factors have been considered, including pesticides and other environmental ...

Environmental factors influencing detection of ring‐necked pheasant broods during August roadside surveys

The Journal of Wildlife Management, Volume 90, Issue 3, April 2026.
We evaluated the influence of environmental factors on detection probability of ring‐necked pheasant broods surveyed during roadside surveys across 11 states. Wind speed, cloud cover, morning dew conditions, and soil moisture influenced detection probabilities and should be the focus of methodological or statistical control in future landscape‐scale ...

Egg-Laying Cycle Characteristics of the Bobwhite (Colinus virginianus)

Poultry Science, 1973
Abstract Egg sequence length, egg production rate, time of oviposition, lag-time and rate of ovum growth were determined for the Bobwhite hen. Hen-housed egg production was 38.9% with an average sequence length of 4.6 eggs when measured over an eight-month production period. The peak period of oviposition was from 11 a.m. to 2 p.m. (EST).

Finding the (small) cores: Spatial covariance tracks grassland bird community occupancy in fragmented grasslands

Ecosphere, Volume 17, Issue 3, March 2026.
Abstract Grasslands are an imperiled ecosystem, and grassland bird abundance is declining across North America. One of the strongest drivers for these declines is woody plant encroachment of grasslands. In the Great Plains and Sagebrush biomes of North America, spatial covariance—a remote‐sensing metric for tracking boundaries between vegetation types ...

Neutral effects of low‐intensity dog training on northern bobwhite vital rates

Wildlife Biology, Volume 2026, Issue 2, March 2026.
Indirect effects of hunting can lead to changes in population dynamics, which can be caused by trait‐mediated effects such as, but not limited to, changes in behavior, reproduction, and physiological responses. Our understanding of the effects of activities associated with hunting such as dog training may incur trait‐mediated effects, and ultimately ...

Biology, Detection, and Management of Lecanosticta acicola: Emerging Challenges for the Management of Brown Spot Needle Blight in Pine Forests

Forest Pathology, Volume 56, Issue 1, February 2026.
ABSTRACT Brown spot needle blight (BSNB), caused by the fungus Lecanosticta acicola, is a widely distributed foliar disease of pines that causes needle necrosis, premature defoliation, and growth loss in both natural forests and commercial plantations. Although L.

Raptor abundance and northern bobwhite survival and habitat use

Wildlife Society Bulletin, 2014
Predation risk has a profound influence on prey behavior and habitat use. The Rio Grande Plains ecoregion of Texas, USA, provides a unique opportunity to investigate changes in prey behavior because the ecoregion experiences a high influx of raptors ...

Northern bobwhite chick survival, growth, and movement in relation to broadcast supplemental feed and drought

Wildlife Biology, Volume 2026, Issue 1, January 2026.
The northern bobwhite is an economically important species across its geographic range that has experienced declining population numbers. There is ample research dedicated to evaluating management practices for the adult life stage. However, effects of management on bobwhite chicks remain understudied, despite this being the most vulnerable age class ...

Helminths and the northern bobwhite population decline: A review

Wildlife Society Bulletin, 2016
Long‐term data from the Breeding Bird Survey and Christmas Bird Count indicate that northern bobwhite (Colinus virginianus; hereafter, bobwhite) populations have declined since 1961 in all but 1 of the 31 states they occupy within the United States. This
