Climate Impacts On North American Quail, Shelby M. Perry, Erin Moser, Jeffrey G. Whitt, Kelly S. Reyna
National Quail Symposium Proceedings
North America’s quail population trends are often linked to regional climate. Extreme climate events such as severe drought, hard freezes, or excessive winter precipitation can reduce quail populations by as much as 84%. Above-average spring and summer temperatures coincident with drought can reduce the laying season for quail by ≤60 days. Exposure of quail eggs to high temperatures during preincubation can initiate and alter embryonic development. Here, we review the impacts of extreme climate events and a changing climate on the survival, reproduction, and population trends of 6 North American quail species: California quail (Callipepla californica), Gambel’s quail …
Analysis Of Predator Avoidance Behavior In California Valley Quail, Curt Vandenberg, Jeffrey G. Whitt, Kelly S. Reyna
Analysis Of Predator Avoidance Behavior In California Valley Quail, Curt Vandenberg, Jeffrey G. Whitt, Kelly S. Reyna
National Quail Symposium Proceedings
Quail populations have been in decline across the United States, primarily due to habitat loss and climate. For remedy, landowners and game managers have attempted to restore populations by releasing captive-reared quail. These releases were largely unsuccessful, presumably due to high predation losses. Recently, there has been an increased interest in quail translocations, which tend to have lower mortality rates than captive-reared bird releases. Translocations are expensive and unpredictable, and require many person-hours; releasing captive-reared quail would be more efficient if the practice were successful. We compared predator avoidance behavior between captive-reared and wild-translocated California quail (Callipepla californica) …
Stress And Predation Impacts On North American Quail Translocations, Curt A. Vandenberg, Sarah A. Currier, Jeffrey G. Whitt, Kelly S. Reyna
Stress And Predation Impacts On North American Quail Translocations, Curt A. Vandenberg, Sarah A. Currier, Jeffrey G. Whitt, Kelly S. Reyna
National Quail Symposium Proceedings
Translocations have been used in attempts to bolster or restore native quail populations for >150 years, often with little success. However, with some northeastern United States quail populations undetectable or extirpated, and others across the United States on the extreme decline, translocation as a tool for quail population restoration is becoming increasingly popular. Two factors contributing to translocation failure are physiological stress and predation. Chronic stress associated with translocations can result in weight loss, reduced immune system function, suppressed reproduction, and an altered fight-or-flight response. These stress-induced responses increase vulnerability to predation, the primary cause of quail mortality. Here, we …
Translocating Wild California Valley Quail To Texas: An Evaluation Of Survival, Dispersal, Tracking Efficacy, And Roost Preference, Garrett Rushing, Jordan T. Conley, Jeffrey G. Whitt, Kelly S. Reyna
Translocating Wild California Valley Quail To Texas: An Evaluation Of Survival, Dispersal, Tracking Efficacy, And Roost Preference, Garrett Rushing, Jordan T. Conley, Jeffrey G. Whitt, Kelly S. Reyna
National Quail Symposium Proceedings
Quail translocations are becoming increasingly popular in regions of suitable habitat where local quail populations have declined. In northeastern Texas, USA, northern bobwhite (Colinus virginianus) populations have drastically declined for over a century and have reached undetectable levels in many areas. As a result, the number of quail hunters and quail conservation funding have also declined. California valley quail (Callipepla californica; hereafter, valley quail) have increased across their range and have been translocated to many states and countries. Thus, the goal of this study was to determine whether translocating wild valley quail to Texas was feasible, …
Avian Abundance And Diversity On Knoxville Wildlife Area In California Following The County Fire Of 2018, Katherine S. Miller, Stacy Martinelli, Levi E. Souza
Avian Abundance And Diversity On Knoxville Wildlife Area In California Following The County Fire Of 2018, Katherine S. Miller, Stacy Martinelli, Levi E. Souza
National Quail Symposium Proceedings
Wildfires can have negative impacts on wildlife during and immediately after a burn event, yet these fires are also necessary for plant succession and biodiversity. Knoxville Wildlife Area (KWA) in Napa County, California, USA is a diverse environment that contains oak woodlands, chaparral, grasslands, and riparian corridors. In July 2018, the County Fire burned 36,353 ha in the Northern California Interior Coast Ranges, including 2,429 ha on KWA. California Department of Fish and Wildlife employees used this opportunity to monitor avian abundance and diversity as the burned area revegetates. From 10 June through 14 June 2019, we began a pilot …
Population Trends And A Revised Management Plan For Quail In California, Katherine S. Miller, Matt G. Meshriy, Scott S. Gardner
Population Trends And A Revised Management Plan For Quail In California, Katherine S. Miller, Matt G. Meshriy, Scott S. Gardner
National Quail Symposium Proceedings
California supports a diversity of habitats suitable for mountain quail (Oreortyx pictus), California quail (Callipepla californica), and Gambel’s quail (Callipepla gambelii). These three species require different habitats for foraging, nesting and brood-rearing, and overwinter survival, yet most published information focuses on California quail. Currently the state-wide surveys for quail are limited to the North American Breeding Bird Survey (BBS) and the Audubon Christmas Bird Count. We used BBS data (1970–2013) to create abundance maps for quail throughout California. We developed 5-year averages to account for boom-and-bust cycles, and then established 100 random points for …

Causes And Consequences Of Mixed-Species Coveys Of California And Gambel’S Quail And Their Hybrids, Jennifer Gee
Causes And Consequences Of Mixed-Species Coveys Of California And Gambel’S Quail And Their Hybrids, Jennifer Gee
National Quail Symposium Proceedings
California (Callipepla californica) and Gambel’s quail (C. gambelii) hybridize where their distributions overlap. Outside of the area of overlap, pairs are known to form within the covey. I observed two mixed-species coveys within the hybrid zone and examined if pairing occurred within the coveys. I compared hatching success and survival of chicks between resident within-covey pairs to immigrant pairs. Isolated coveys could become inbred, given that choice of conspecific mate may be constrained by small population size. I measured relatedness between quail for each individual that paired within the covey, and tested whether it was more or less related to …
Cyclicity In Northern Bobwhites: A Time-Analytic Review Of The Evidence, Wayne E. Thogmartin, John L. Roseberry, Alan Woolf
Cyclicity In Northern Bobwhites: A Time-Analytic Review Of The Evidence, Wayne E. Thogmartin, John L. Roseberry, Alan Woolf
National Quail Symposium Proceedings
Cyclical behavior in wildlife populations, including northern bobwhite (Colinus virginianus), has long fascinated human observers. However, studies examining cyclicity of bobwhite abundance have yielded contradictory results. We reviewed evidence for periodic fluctuation in bobwhite abundance by studying 73 long-term time series. Our aim was to discern with time-series techniques whether cyclicity occurred in bobwhite abundance. We elucidated the frequency of occurrence, geographical distribution, and potential mechanisms responsible for cyclicity. Approximately one-half (n = 37) of the populations examined demonstrated cyclical behavior, with a period varying between 4 and 17 yrs. True cycles, consistent, significant fluctuations in abundance, were rare, occurring …
Bobcat Predation On Quail, Birds, And Mesomammals, Michael E. Tewes, Jennifer M. Mock, John H. Young
Bobcat Predation On Quail, Birds, And Mesomammals, Michael E. Tewes, Jennifer M. Mock, John H. Young
National Quail Symposium Proceedings
We reviewed 54 scientific articles about bobcat (Lynx rufus) food habits to determine the occurrence of quail, birds, and mesopredators including red (Vulpes vulpes) and gray fox (Urocyon cinereoargenteus), raccoon (Procyon lotor), skunk (Mephitis spp.), and opossum (Didelphis virginianus). Quail (Colinus virginianus, Cyrtonyx montezumae, Callipepla squamata, C. gambelii, C. californica, Oreortyx pictus) were found in 9 diet studies and constituted 3% of the bobcat diet in only 2 of 54 studies. Birds occurred in 47 studies, but were also a minor dietary component in most studies. Although mesopredators were represented as bobcat prey in 33 of 47 studies, their percent …
Appendix A: Strategic Plan For Quail Management And Research In The United States: Introduction And Background, Leonard A. Brennan
Appendix A: Strategic Plan For Quail Management And Research In The United States: Introduction And Background, Leonard A. Brennan
National Quail Symposium Proceedings
I assessed the current, broad-scale status of populations, research, and management for 6 species of quail in the U.S., and used this information as an introduction, background, and justification for a national strategic planning effort for quail management and research. Long-term (1960-89) trends determined from Christmas Bird Count data indicate that California quail (Callipepla californica), northern bobwhite (Colinus virginianus), and scaled quail (Callipepla squamata) populations have undergone (P < 0.05) declines. Geographic distribution of mountain quail (Oreortyx pictus) has contracted dramatically in the northeastern portion of this quail's range. Neither Gambel's (C. gambelii) nor Montezuma quail (Cyrtonyx montezumae) showed evidence of long-term increases or decreases. Wildlife professionals have apparently paid scant attention to quail in the U.S. during the past 10 years. A recent survey of Wildlife Review indicated <0.2% of the publications pertained to quail. During 1990, < 1.0% of Federal Aid in Wildlife Restoration funds were allocated to quail-related projects. Habitat management by the private sector is apparently having little broad-scale impact on bobwhite populations. Contemporary quail management efforts in the U.S. are clearly in the doldrums and in dire need of leadership from professionals with a creative vision for solving problems caused by changing land-use practices. These factors point to a critical need for a national strategic planning effort to develop a comprehensive, coordinated program for quail management and research. An outline of the structure of the Strategic Planning Workshop that was held at Quail III is provided. Specific management and research problems and associated strategies for solving them are available in Issues and Strategies, which follows (page 181).
California Quail In Western Oregon: A Review, John A. Crawford
California Quail In Western Oregon: A Review, John A. Crawford
National Quail Symposium Proceedings
Habitat use by California quail (Callipepla californica) was studied at the E. E. Wilson Wildlife Area in northwestern Oregon, a mesic extension of the range of this species, from 1974 to 1992. Abundance of quail on the area was related to plant succession. Dietary studies revealed that legumes-particularly deervetch (Lotus spp.), peavine (Lathyrusspp.), Scot's broom (Cytisusscoparius), and vetch (Viciaspp.)-oomposed 67% of the relative dry mass of the annual diet. California quail typically nested in shrub/grassland and roadside habitats with less grass and shrub cover and more bare ground than at random locations within those cover types. Blackberry (Rubus spp.) stands …
