“…The Northern Bobwhite (Colinus virginianus) is both a declining species of concern and a managed game species. Bobwhite decline has progressed for decades and is linked to habitat loss and population fragmentation due to urbanization and changes in agricultural practices (Brennan 1991, Church et al 1993, Guthery et al 2000, McKenzie 2009, Hernández et al 2013. A range-wide adaptive management approach, including research, monitoring, education, and habitat management, is needed to increase populations (Brennan 1991, Palmer et al 2011, Hernández et al 2013.…”

We examined the use of autonomous recording units for monitoring Northern Bobwhite (Colinus virginianus) in South Carolina and compared results with those of traditional point count surveys conducted simultaneously at overlapping points. We assessed seasonal patterns and quail encounter rates for traditional and recorded surveys and used random forest modeling to determine which location and survey-based variables are most important. We found both survey methods have similar encounter rates, but seasonal occupancy rates are significantly higher when the more extensive automated recording data are used. Both survey methods indicate that location-based variables are most important to encounter rate, and both adequately account for survey detectability, but the use of recordings reduces survey bias. The autonomous recording method also permits an increase in survey and season length without increasing the labor necessary for monitoring. Both survey methods indicate a peak encounter rate in June consistent with the current protocols and with similar studies in nearby regions. The use of recordings, however, allows for extensive tracking of seasonal patterns and would be beneficial for long-term monitoring. Overall, traditional methods are more conducive to abundance surveys, whereas recordings are more appropriate for occupancy or encounter rate studies. We suggest a combination of both point count and autonomous recording methods as a feasible way to expand and improve monitoring of bobwhite populations.RESUMEN. Examinamos el uso de unidades de registro autónomas para monitorear a la especie Colinus virginianus en Carolina del Sur y comparamos los resultados con los monitoreos tradicionales de puntos de conteo realizados simultáneamente en puntos que se sobreponen. Evaluamos los patrones estacionales y las tasas de encuentro de codornices para censos tradicionales y muestreos grabados y utilizamos modelos forestales aleatorios para determinar cuáles ubicaciones y variables basadas en los muestreos son más importantes. Descubrimos que ambos métodos de muestreo tienen tasas de encuentro similares, pero las tasas de ocupación estacional son significativamente más altas cuando se utilizan datos de registros automatizados más extensos. Ambos métodos de muestreo indican que las variables basadas en la ubicación son las más importantes para las tasas de encuentro, y ambos explican adecuadamente la detectabilidad durante los muestreos, pero el uso de grabaciones reduce el sesgo de la encuesta. El método de registro automático también permite aumentar el muestreo y de la duración de la temporada sin aumentar la mano de obra necesaria para el seguimiento. Ambos métodos de muestreo indican una tasa máxima de encuentro en junio consistente con los protocolos actuales y con estudios similares en regiones cercanas. Sin embargo, el uso de grabaciones permite un seguimiento exhaustivo de los patrones estacionales y sería beneficioso para el seguimiento a largo plazo. En general, los métodos tradicionales son más propicios para los ...

The northern bobwhite (Colinus virginianus) decline has become a cause ce´le´bre of wildlife conservation during the past 2 decades. With few exceptions, current broad-scale population trends show ongoing erosion in bobwhite numbers across most of the species' range. The causes of these declines are ultimate factors exacerbated by certain proximate factors. Ultimate factors are centered on the loss and fragmentation of habitat. Proximate factors such as predation and disease also may be present. The impacts of some factors, such as climate change, remain unknown but may influence bobwhite population trajectories over the long term. Progress has occurred in bobwhite conservation efforts since 1990 and has culminated in the formation of the National Bobwhite Technical Committee and the publication of the Northern Bobwhite Conservation Initiative. The vast majority of prevailing agricultural, forestry, and to some extent rangeland land uses in the United States continue as threats to bobwhite population persistence in the foreseeable future. Land-use patterns that once sustained widespread abundance of northern bobwhite during the early 20th century clearly are past and likely never to return. Landscape features that sustain and elevate northern bobwhite populations will only be maintained as a function of purposeful management actions directed at saving and creating usable space. ß 2012 The Wildlife Society.KEY WORDS adaptive management, bobwhite, Colinus virginianus, conservation planning, northern bobwhite, Northern Bobwhite Conservation Initiative, quail.Two decades ago, Brennan (1991) published an article titled, ''How can we reverse the northern bobwhite population decline?'' The publication outlined a series of observations and issues related to factors that were responsible for the nearly range-wide decline of the northern bobwhite (Colinus virginianus). Northern bobwhites had been declining at a considerable rate across their geographic range prior to 1991, but very few conservationists had taken notice. The publication of Brennan (1991) seemed to awaken a complacent quail profession that did not appreciate the general status of northern bobwhite in the United States at the time.Since the publication of Brennan (1991), considerable effort has been directed at the conservation of northern bobwhite and its habitat. When cast in a broader context of the past 2 decades, it is clear that bobwhite conservation efforts have gained traction, and perhaps even an element of critical mass, that will provide a basis for further achievement. We examine what has happened to the northern bobwhite over the past 20 years in the context of ultimate and proximate factors that influence their mostly declining populations. We identify ongoing and emerging threats to bobwhite conservation and discuss the initiatives that wildlife professionals, landowners, quail hunters, and conservationists have developed in an effort to stop the decline. Lastly, we use this paper as a forum to clarify some misunderstandings that were ...
