Abstract Our understanding of the frequency of brood amalgamation in the Northern Bobwhite (Colinus virginianus) is largely anecdotal. Information on it is important in understanding survival and reproduction. We captured entire bobwhite broods at 3–4 and 10–12 d of age and individually marked each bobwhite chick within a brood. Broods were considered amalgamated if novel unmarked or marked individuals or significant differences in body mass or flight ability among chicks were observed. During…

Evaluating the Efficacy of Brood Flush Counts: A Case Study in Two Quail Species

Radio-tagged Northern Bobwhite and Scaled Quail chicks and juveniles were used to estimate and compare brood survival using 2 analysis methodologies, and flush counts provided a more accurate estimate of brood survival for Scaled quail than for bobwhites.

Brood success of northern bobwhite is biased by incomplete detectability during flush-counts

This work sought to estimate detection probability of chicks during flush-counts as a function of vegetation height and adult brooding behavior, and evaluated compromises in detection by comparing estimates of brood survival derived from flush- Counts and radiotelemetry.

Achieving Better Estimates of Greater Sage-Grouse Chick Survival in Utah

It is found that survival may be higher among chicks that switch broods compared to those that stayed with their natal mother until fledging, which is the highest level ever documented for this long-lived species.

Survival and Reproduction of Parent-Reared Northern Bobwhites

A parent-rearing technique is developed that facilitates preand post-hatch imprinting using parent- reared wild strain northern bobwhite chicks in outdoor pens and may useful for restoring or enhancing bobwhites populations at the local scale.

Demographic Sensitivity of Population Change in Northern Bobwhite

Simulation results indicate that management practices that improve seasonal survival rates will have the greatest potential benefit for recovery of declining populations of bobwhites.

Factors influencing reproductive performance of northern bobwhite in South Florida

The reproductive output in the study population was lower than that reported for most other bobwhite populations, indicating that low reproductive performance may have contributed to bobwhite population declines in the authors' study site, and suggest that current management practices, particularly those related to habitat and harvest management, need careful evaluation.

Temporal and scalar variations affect resource use of northern bobwhite broods

Evaluated resource use of northern bobwhite at two spatial scales and across three age classes, from hatching through a period of the postjuvenile molt, finding broods may alter resource use with changes in vulnerabilities to threats such as thermal risks and predation.

Nest success and brood habitat selection of the northern bobwhite in Southeast Iowa

Compared nest success of rad~otagged bobwhite in 2 landscapes in southeastern Iowa, it is suggested that bobwhite may in fact make nest site selection choices on the landscape scale, even though this may not ultimately affect success.

Population genetic structure among bobwhite in an agriculturally modified landscape

The low amount of genetic structure detected in bobwhite collected by hunters in southern and central counties of Illinois may be an early indication of genetic drift occurring due to recent landscape changes that may be isolating bobwhite subpopulations.

Gang-brooding in Northern Bobwhites in West Texas

The occurrence of gang-brooding (i.e., communal brood-rearing) in a population of Northern Bobwhites (Colinus virginianus) in western Texas is reported.

Facultative Communal Brood Rearing in California Quail

Parents of communal brooding in California Quail Callipepla californica lived significantly longer than parents of single broods and hatched significantly more young during their lifetimes and those that raised their first surviving brood communally were significantly more likely to hatch a brood the following year.

Pre-hatch and post-hatch brood amalgamation in North American Anatidae: a review of hypotheses

The frequency of occurrence of brood amalgamation in North American anatids is analyzed and the hypotheses that have been proposed to explain these behaviours are reviewed to erect a theoretical framework which applies to these behaviours.

A technique for capturing northern bobwhite chicks

A technique for capturing northern bobwhite chicks 3 directions was developed, independent of chick age, up to 12 days of age, and may have utility for researchers studying brood ecology of northern bob white or other precocial birds.

Northern bobwhite chick mortality caused by red imported fire ants

Results indicate northern bob white chicks can suffer high levels of mortality due to red imported fire ants, which could explain declines in some northern bobwhite populations following infestations by red importedFire ants.

The reproductive system of northern bobwhite enables recovery from low annual survival or periodic catastrophic declines and may be an adaptation to fluctuating resources in ephemeral, dynamic habitats.

Estimating prefledging survival: allowing for brood mixing and dependence among brood mates

A model for estimating survival of young waterfowl from hatch to fledging is developed that enables interchange of individuals among broods and relaxes the assumption that individuals within broods have independent survival probabilities.
