Abstract: Numerous studies of behavior and ecology northern bobwhites ( Colinus virginianus ) have depended on radiotagging telemetry for data collection. Excluding the presumably short‐term effects trapping, handling, attaching radiotransmitters, researchers often assume that little bias is associated with estimating survival behavioral parameters this technique. However, not adequately examined these organisms being investigated thus assumed demographic information obtained from such...

Habitat fragmentation, degradation, and loss have taxed early‐successional species including the Northern Bobwhite ( Colinus virginianus ) numerous grassland obligate birds. Translocation is often applied to counteract consequences of habitat fragmentation through creation, reestablishment, or augmentation wild populations for purposes conservation, biodiversity maintenance. However, implementation these techniques conducted without valid experimental designs therefore lacks robust,...

Habitat quality influences individual survival at widely varying spatial and temporal scales. Understanding interactions between habitat among individuals in declining populations that occupy highly modified landscapes can inform conservation strategies aimed improving population growth. We used radiotelemetry to monitor space use daily of wintering Northern Bobwhites (Colinus virginianus) the northern end their range test for fine spatial- temporal-scale relationships composition around...

ABSTRACT Nest predation is the major cause of nest failure in northern bobwhites ( Colinus virginianus ; i.e., bobwhites). Control mid‐sized mammalian predators (i.e., meso‐mammals) often conducted to increase reproductive success on lands managed for bobwhites. by meso‐mammals, however, only one part a complex predator‐prey trophic system. There limited understanding effect bobwhite demographics, which creates uncertainty about efficacy predator control. We quantified demographic effects...

ABSTRACT Reliable vital rates for all life stages are necessary to identify limiting factors in wildlife populations and inform sound management. The difficulty associated with capturing tagging precocial young, such as northern bobwhite chicks ( Colinus virginianus ), linking variation recruitment ecological conditions has contributed significant knowledge gaps their population ecology. During 1999–2017, we captured patagial‐tagged ≤12‐day‐old n = 3,576) estimated survival from time of...

During 1997 and 1998, we implemented a pilot investigation to compare survival, site fidelity, reproductive characteristics of relocated wild northern bobwhites (Colinus virginianus) with that resident birds. We captured (n = 74) on managed lands in southern Georgia them (>1.6 km from capture sites) sites nearby where density estimates revealed population was low compared surrounding sites. equipped translocated birds radiotransmitters released groups 8–12. also 166) simultaneously monitored...

Long-term studies are imperative to increase our knowledge of northern bobwhite (Colinus virginianus; hereafter bobwhite) demographics. During 1992-2005, we determined survival and cause-specific mortality bobwhites on 10 study areas in southern Georgia eastern Alabama, USA.We radio-tagged 7,105 49 annual (Oct-Sep) 110 seasonal estimates examine spatial temporal variation survival. Annual for all sites years combined averaged 0.196 (SE = 0.011) ranged from 0.08 0.40. Over-winter (Oct - Mar)...

ABSTRACT Animals inhabiting disturbance‐prone systems, such as the northern bobwhites ( Colinus virginianus ) in pine Pinus spp.) savanna, are adapted to certain intensities of disturbance (e.g., frequency, spatial extent, seasonality). Management practices attempt mimic these natural conditions. Even though known firebird, most fire‐related management is currently based on tradition and limited peer‐reviewed literature. We studied habitat selection private property Georgetown County, South...

Perceived changes in predator—prey dynamics along with documented declines of northern bobwhite Colinus virginianus have created a renewed interest from biologists and managers about the role meso‐mammals play shaping population trajectories. Therefore, we evaluated efficacy meso‐mammal trap removal (MMTR) at reducing activity increasing reproductive success; thus testing predation limitation hypothesis. During 1999–2006, monitored reproduction on 11 sites three states across southeastern...

ABSTRACT Prey species must consistently balance the need for resource acquisition with threat of predation. This is particularly true gallinaceous birds, such as northern bobwhite ( Colinus virginianus ), which are ground foragers and often exposed to increased predation risk compared arboreal foragers. We studied how bobwhites might mitigate human hunting pressure by altering their foraging strategy. directly monitored encounters bobwhites, during October 2014–March 2015, collected daily...

ABSTRACT Reliable and unbiased information is needed for informing management decisions relevant to all animal life stages. Radiomarking commonly used adult birds, but this approach more challenging galliform chicks. Following preliminary experimentation of multiple attachment methods, we selected 2 radiotransmitter techniques, gluing suturing, test on 11‐day‐old northern bobwhite ( Colinus virginianus ; hereafter, bobwhite) chicks in an outdoor aviary environment during 1 May 2013 through...

ABSTRACT Relationships between northern bobwhite ( Colinus virginianus ) population dynamics and weather are well‐established managed in the southern western core of their range. Although a qualitative recognition effects winter at edge range exists, quantitative evaluations that examine impacts severe events on declining populations lacking. We used radiotelemetry to evaluate relationships daily survival 2 Maryland Ohio, USA. Ninety‐day (Dec–Feb) varied with total snow accumulation among...

Gamebird translocations have been used for many years to establish or re-establish populations in North America. A long-term severe decline of northern bobwhites (Colinus virginianus) over much their range has brought this issue the forefront species as well. Field studies Georgia last decade documented site fidelity, high survival, reproductive success, and population response from translocated into large blocks well-managed habitat. The Department Natural Resources/ Wildlife Resources...

ABSTRACT The influence of harvest on wild populations has been the focus substantial debate, and widespread implications for management populations. Traditional views are based density‐dependent responses to harvest. However, alternate mechanisms can do induce compensation (e.g., individual heterogeneity). Selective successful females their offspring is thought occur in some grouse blue [ Dendragapus spp.], greater sage‐grouse Centrocercus urophasianus ]), delaying within a season proposed...

The National Bobwhite Conservation Initiative (NBCI 2.0) is a range-wide plan for recovering northern bobwhites (Colinus virginianus; hereafter, bobwhite[s]). Using geospatial analysis informed by expertise from practitioners, the categorizes landscapes into restoration potential weighing biological constraints and opportunities such that targeted habitat management will produce bobwhite population growth. A fundamental assumption of NBCI 2.0 achieving recovery goals source populations...

As a case study, New Jersey Pine Barrens (NJPB) are disturbance driven ecosystem that is experiencing serious ecological implications due to loss traditional forest thinning activities such as harvesting for products or wildfire fuel-load reduction measures coupled with long-standing philosophy fire dormant-season prescribed burning. Dense closed-canopy conditions, dissimilar historic...
