SummaryDiets of nesting Red-tailed Hawks (Buteo jamaicensis) and Ferruginous Hawks (Buteo regalis) were sampled before and after a decline in the hawks' principal prey species. Diets of pairs that shared their foraging ranges with interspecifics were contrasted with those of pairs whose home ranges did not overlap with interspecifics. Current theory predicts that diets should diverge during prey shortages and that overlap should be especially reduced in ranges shared with interspecifics… Expand

Tables and Topics from this paper

Dietary shifts, niche relationships and reproductive output of coexisting Kestrels and Long-eared Owls
TLDR
In the breeding season, interspecific competition for food seems to be an important factor that affects the niches of these species, especially in northern areas, where the seasonal low phase of voles in spring and the number of alternative prey are lower than in more southern areas. Expand
Broad-Winged Hawk Nesting Behavior in Forested Landscapes of Pennsylvania
TLDR
The relationship between forest fragmentation and Broad-winged Hawk nesting ecology warrants further investigation, and the absence of adults at the nests during nestling and fledgling periods may leave young vulnerable to predators. Expand
The relationship between intra–guild diet overlap and breeding in owls in Israel
TLDR
In Israel, when these two owl species prey more often on rodents, their diets are more similar and interspecific competition is reduced, unlike sympatric populations in Europe, in years when rodents are less abundant in Israel. Expand
Multi-isotopic assessments of spatio-temporal diet variability: the case of two sympatric gulls in the western Mediterranean
TLDR
The usefulness of 3-dimensional isotope analyses to correctly assess spatio-temporal variability in trophic behaviour of predator species is emphasized, revealing differences that would remain hidden in single population studies or when using only the isotopic ratios of 2 elements. Expand
Potential competition between two top-order predators following a dramatic contraction in the diversity of their prey base
TLDR
To minimise potential competition, longterm feral predator control and improved habitat management is recommended to increase the density and diversity of small terrestrial mammals, as this should result in diversification of the sooty owl diet, reducing dietary overlap with powerful owls. Expand
Competition and patterns of resource use by two sympatric raptors
TLDR
It is concluded that direct competition for food did not take place between these two hawks because such competition was mediated by competition for territories and the subsequent partitioning of space. Expand
PREY USE AND PROVISIONING RATES OF BREEDING FERRUGINOUS AND SWAINSON'S HAWKS ON THE SOUTHERN GREAT PLAINS, USA
TLDR
Diet data at Ferruginous and Swainson's Hawk nests in a short-grass prairie and agricultural community in the panhandle area of northwest Texas and southwest Oklahoma, and in northeastern New Mexico during the 2003–2004 breeding seasons represent the most accurate diet quantification to date. Expand
Adjusted Diets of Bald Eagles (Haliaeetus leucocephalus) Breeding In An Altered Estuary
TLDR
Florida Bay's ecological and prey community changes during this time period influenced Bald Eagle diets, and Mullet, jack, Jack, Double-crested Cormorant, and Red-breasted Merganser were the species that contributed most to the dissimilarities between time periods. Expand
Home Ranges of Gopher Snakes (Pituophis catenifer, Colubridae) in Central California
TLDR
Radio-tracked four adult male Pituophis catenifer (gopher snake) in central California for 14 consecutive months to investigate spatial and seasonal movement patterns and suggest that syntopic gopher snakes occupy exclusive home ranges during at least part of their active season. Expand
Prey use and productivity of ferruginous hawks in rural and exurban New Mexico
Habitat loss from human development affects native wildlife populations, especially in the western United States where the human population is growing 2–3 times faster than any other part of theExpand

Variation in surfperch diets between allopatry and sympatry: circumstantial evidence for competition
TLDR
Allopatric E. jacksoni displayed patterns of selectivity for prey of various sizes that were qualitatively different from those displayed by black surfperch sympatric with E. lateralis, and there was an apparant divergence in prey use by co-occurring Embiotoca species. Expand
Coexistence of three species of hawks (Buteo spp.) in the prairie-parkland ecotone.
TLDR
It was concluded that food was not a resource for which the hawks were competing because the overlap in diets exceeded 80%, and because ferruginous hawks successfully fledged supernumerary broods and Swainson's hawks, broods of at least average size. Expand
POPULATION DYNAMICS OF THE FERRUGINOUS HAWK DURING A PREY DECLINE
— a nesting population of Ferruginous Hawks (Buteo regalis) at the eastern edge of the Great Basin in west-central Utah was studied for three nesting seasons, 1972-1974, during which time aExpand
Niche Relationships Among Six Species of Shorebirds on Their Wintering and Breeding Ranges
TLDR
The dynamics of the organization of a community of six species of migrant predatory shorebirds was appraised by studying foraging behavior and habitat utilization under winter conditions in southern Florida and under summer conditions in the eastern Canadian Arctic. Expand
Diet niche relationships among North American grassland and shrubsteppe birds
TLDR
The findings seem generally most consistent with the suggestion that food is not normally limiting to bird populations in these systems, and individuals and populations are exploiting the food resources in an opportunistic fashion, which leads to considerable individual, between-year, and between-location variation in diet compositions and interspecific overlaps. Expand
Relationships between Jackrabbit Abundance and Ferruginous Hawk Reproduction
TLDR
Regression tests revealed that two of these, the failure to nest and achieve maximum clutch size, are important limiting factors on reproduction and at least partially act to regulate the size of this Ferruginous Hawk population. Expand
Presence and Absence of Habitat Shift in Some Widespread Lizard Species
TLDR
Results imply that animals similar to widespread forms in some niche dimension other than structural habitat are those most likely to cause shift in structural habitat and suggest existence of a competition function with respect to size. Expand
Predatory responses of a raptor guild to changes in prey density
TLDR
The responses of a guild of open-country birds of prey to changes in prey density were studied on a simple island habitat in southern Ontario, finding a basic similarity in the form of response for all species present at any one season and a complementarity of responses of species present through the changing seasons resulted in an overall guild level pattern. Expand
Seasonal dynamics of resource partitioning among foliage-gleaning passerines in northern Finland
TLDR
In these northern forests foliage-gleaners must be versatile generalists to cope with the unpredictable resources, and thus they overlap broadly in their general resource niches which are determined by their genetically fixed cost and benefit relations to each resource type. Expand
Optimal diets in complex environments: feeding strategies of two herbivorous fishes from a temperate rocky intertidal zone

TLDR
It is indicated that optimal diet models cannot be based solely on energy maximization but should also include nutrient constraints in order to more accurately predict the seasonally fluctuating mixed diets of these fishes and other generalist herbivores. Expand
