Abstract Supplemental feeding is a widely used management practice in areas managed for northern bobwhite (Colinus virginianus; hereafter quail). Although food provisioning is intended to benefit quail directly, it may also indirectly affect predators by allowing them to focus on the increased concentration of prey. We studied the effects of food supplementation for northern bobwhite on red-tailed hawk (Buteo jamaicensis) space use in a longleaf pine (Pinus palustris) ecosystem in southwestern… Expand
Effects of broadcasting supplemental feed into roadside vegetation on home range and survival of female northern bobwhite
TLDR
It is suggested that distributing supplemental feed into roadside vegetation positively influences bobwhite survival with no reduction in home range size. Expand
Species visitation at free-choice quail feeders in west texas†
TLDR
It is concluded that the vast majority of the feed in this study was consumed by non-target species and most notably raccoons, suggesting supplemental feeding programs for quail could facilitate targeted removal of a common feed competitor (and potential predator of quail nests) and perhaps improve efficacy of feeding efforts.

An evaluation of supplemental food to increase winter survival of cottontail rabbits
The New England cottontail is currently endangered throughout much of its range. The cause of this decline has been habitat loss that has facilitated intense predation. Cottontails living on smallExpand
Can supplemental food increase winter survival of a threatened cottontail rabbit
TLDR
It is concluded that supplemental feeding may improve survival of remaining New England cottontails as efforts to increase habitat availability continue to develop. Expand
USE OF SUPPLEMENTAL NORTHERN BOBWHITE ( Colinus virginianus ) FOOD BY NON-TARGET SPECIES
— Several studies have investigated the use of supplemental feeders by Northern Bobwhites ( Colinus virginianus ) and non-target species, but none have previously examined the use of food spreadExpand
Feeding Ecology of the Snake Community of the Red Hills Region Relative to Management for Northern Bobwhite: Assessing the Diet of Snakes Using Stable Isotopes
TLDR
Using milo to reflect dietary patterns, it was determined that Coachwhip, Cottonmouth, and Eastern Rat Snake were dietary generalists, revealed by larger isotopic range and lack of correspondence between isotopic values and those of distinct prey groups. Expand
Predator abundance in relation to small game management in southern Portugal: conservation implications
TLDR
There was little evidence that game management reduced local predator abundances, except in the most intensively managed estates, and whether high prey densities may attract predators to game estates with increased mortality risk, which may thus become population sinks for protected species. Expand
Effects of Mesopredators and Prescribed Fire on Hispid Cotton Rat Survival and Cause-Specific Mortality
TLDR
It is suggested that managing mesopredators may result in a temporary increase in cotton rat survival, but dormant season prescribed fire removes this effect until well into the following growing season. Expand
Supplementing non-target taxa: bird feeding alters the local distribution of mammals.

TLDR
Because many mammals depredate bird nests, the local increases in mammal richness and activity near bird feeders may create an ecological trap for avian species nesting in close proximity to supplemental feeding stations. Expand
Abundance of wild prey modulates consumption of supplementary food in the Iberian lynx
TLDR
Understanding how the abundance of natural food modulates consumption of supplemental food may help to adjust supplementation schedules to food availability and to the needs of the target populations. Expand

SPACE-USE PATTERNS OF BOBCATS RELATIVE TO SUPPLEMENTAL FEEDING OF NORTHERN BOBWHITES
TLDR
The data suggest that supplemental feeding of prey can result in a spatial response by predators, and further research is needed to determine whether supplementalfeeding of prey attracts other top predators and whether supplemental feeding results in decreased prey survival by attracting predators. Expand
Using supplemental food and its influence on survival of northern bobwhite (Colinus virginianus)
TLDR
Results suggested that bobwhites can gain nutritional benefits from suppiemental feeders during times of severe winter stress. Expand
Ecology of Red‐Tailed Hawk Predation in Alberta
TLDR
The Red—tailed Hawk population on a 60—mile2 (156—km2) area in central Alberta was studied, and Richardson's ground squirrels were significantly more vulnerable than adult females and there was no consistent relationship between snowshoe hare and Ruffed Grouse densities and their utilization by red—tails. Expand
EFFECTS OF SUPPLEMENTAL FOOD ON PARENTAL-CARE STRATEGIES AND JUVENILE SURVIVAL OF NORTHERN GOSHAWKS
TLDR
Overall patterns of mass and nest-attendance for adult female goshawks supports the hypothesis that female condition and behavior are adjusted in response to food supplies, and the apparent flexibility in female nest attendance behavior suggests that such plasticity may be an adaptation to lower the risk of predation. Expand
Red-shouldered hawk home-range and habitat use in southern California
TLDR
Red-shouldered hawks used 4 woodland habitats more than expected due to chance, and 4 nonwoodland habitats less than expected; the overall pattern of habitat use was the same for both sexes. Expand
ECOLOGY of GREAT HORNED OWLS and RED-TAILED HAWKS in SOUTHEASTERN WISCONSIN
During 1911-75, a study of great horned owls and redtailed hawks was undertaken on a 8373-ha acre in southern Wisconsin (43° lO'N, 88° 50'W). The objectives of the study were: (1) to determineExpand
Effects of supplemental food on population dynamics of cotton rats, Sigmodon hispidus
TLDR
The data support a scenario of territorial females and wandering males in the reproductive season, with females maximizing resource acquisition for production of off- spring during winter, and both sexes may restrict foraging time to the minimum required for survival during winter. Expand
FOOD LIMITATION ON BROOD SIZE: EXPERIMENTAL EVIDENCE IN THE EURASIAN KESTREL
TLDR
While females adjusted parental effort to male provisioning and offspring requirements, males did not change parental- effort within a season, suggesting that male parental effort is fixed at a level where male survival is not jeopardized. Expand
EFFECTS OF SUPPLEMENTAL FOOD ON SIZE AND SURVIVAL OF JUVENILE NORTHERN GOSHAWKS
TLDR
Because most control nestlings died from predation, higher nestling survival is attributed to increased time spent in nest stands by adult females, whose presence probably deterred predators. Expand
Effects of supplemental prey, vegetation, and time on success of artificial nests
TLDR
Prey supplementation may be useful when used in conjunction with habitat management for dense nesting cover or in areas that already have dense vegetation, and dense vegetation increased artificial nest survival. Expand
