Abstract We measured an index of Red-shouldered Hawk (Buteo lineatus) abundance along streams in southern Ohio and related differences in abundance index to landscape-scale habitat characteristics within the surveyed areas. Fifteen study sites, each a 5.8-km reach of a permanent stream, were surveyed four times using broadcasts of Red-shouldered Hawk calls and Red-tailed Hawk (Buteo jamaicensis) calls. We determined the landcover types in a corridor surrounding each surveyed area using a GIS… 

Habitats of Suburban Barred Owls (Strix varia) and Red-Shouldered Hawks (Buteo lineatus) in Southwestern Ohio1

Habitat of suburban Barred Owls differed little from habitat of suburban Red-shouldered Hawks in southwestern Ohio, and values of land-cover percentages and metrics did not differ between the species.

Nest Density, Productivity, and Habitat Selection of Red-Shouldered Hawks in a Contiguous Forest

The low reproductive success in combination with the observed nest density suggests that immigration of Red-shouldered Hawks from outside the study area may be critical to maintaining this breeding population.

HOME RANGE AND HABITAT USE OF SUBURBAN RED-SHOULDERED HAWKS IN SOUTHWESTERN OHIO

Most Red-shouldered Hawks used riparian zones and pond edges more than expected, based on availability of such habitats within their home ranges; residential areas and lawns were used less than expected or in proportion to their availability.

Raptor Presence Along an Urban–Wildland Gradient: Influences of Prey Abundance and Land Cover

Raptor species richness was consistent across the gradient of urbanization and not correlated with land-cover diversity, songbird species richness, or total forest cover and Cooper's Hawks and Barred Owls showed a positive response to human-altered landscapes.

Spatial and Temporal Variation in Reproductive Rates of the Red-Shouldered Hawk in Suburban and Rural Ohio

It is suggested that differences among the nest areas in reproductive rate likely indicate differences in habitat quality of individual nest areas, whereas differences among years likely reflect regional factors that influence nesting birds, such as weather.

BEHAVIOR AND PREY OF NESTING RED-SHOULDERED HAWKS

Direct observations to quantify prey types, prey delivery rate, and adult and nestling behavior at nests of Red-shouldered Hawks in suburban southwestern Ohio may serve as a baseline for assessing prey delivery rates and behavior of populations of REDHawks throughout the lower Midwest.

Journal of Caribbean Ornithology, Vol. 33: Lesser Black-backed Gulls (Larus fuscus) in Saint Vincent and the Grenadines and Grenada

Because raptors usually occur at low densities and occupy large territories, they can be particularly sensitive to habitat degradation and loss. However, the impacts of these environmental changes on

METHODS TO CORRECT FOR DENSITY INFLATION BIASES IN HAWAIIAN HAWK SURVEYS USING ATTRACTANT CALLS

ABSTRACT Point-count surveys with playback recordings have been used to estimate density and abundance for Hawaiian Hawks (‘Io; Buteo solitarius) on Hawaii. Playbacks are necessary for effective

Red-Shouldered Hawks: Adaptable Denizens of the Suburbs

With its beautiful black-and-white wings and tail contrasting with a richly rusty body and its insistent “kee-kee-kee” calls, the red-shouldered hawk (Buteo lineatus) is a welcome neighbor for many

STATUS, NESTING DENSITY, AND MACROHABITAT SELECTION OF RED-SHOULDERED HAWKS IN NORTHERN NEW JERSEY

ABsTRAcr.-Response rates of Red-shouldered Hawks (Buleo lineatus) and Red-tailed Hawks (B. jamaicensis) to broadcast vocalizations in suitable/marginal Red-shouldered Hawk habitat indicated that the

Home range and habitat use of red-shouldered Hawks in Georgia

The objectives of this study were to establish the home range size and habitat requirements of the Red-shouldered Hawk within an intensively-managed pine forest and to provide information useful in formulating a management plan for Red- shouldered Hawks in managed forests of the Southeast.

NEST-SITE SELECTION OF RED-SHOULDERED AND RED-TAILED HAWKS IN A MANAGED FOREST

We compared nest-site macro- and microhabitat selection of Red-shouldered (Buteo lineatus) and Red-tailed hawks (B. jamaicensis) and examined potential relationships between habitat selection and

Nest-site habitat selected by woodland hawks in the central Appalachians

--We quantitatively describe the nest-site habitat selected by Broad-winged Hawks (Buteo platypterus), Red-shouldered Hawks (B. lineatus), Red-tailed Hawks (B. jamaicensis), and Cooper's Hawks

RED-SHOULDERED HAWK NEST SITE SELECTION IN NORTH-CENTRAL MINNESOTA

Abstract We evaluated characteristics at Red-shouldered Hawk (Buteo lineatus) nest sites at two study areas with different topography and forest types in north-central and central Minnesota to

Red-shouldered hawk broadcast surveys: Factors affecting detection of responses and population trends

Forest-nesting raptors are often difficult to detect and monitor because they can be secretive, and their nests can be difficult to locate. Some species, however, respond to broadcasts of taped

NEST SITE SELECTION AND PRODUCTIVITY OF SUBURBAN RED-SHOULDERED HAWKS IN SOUTHERN OHIO

Abstract We measured nest site selection and productivity of suburban-nesting Red-shouldered Hawks (Buteo lineatus) in southwestern Ohio and rural-nesting Red-shouldered Hawks in south-central Ohio.

Surveying woodland hawks with broadcasts of great horned owl vocalization

Pre-recorded vocalizations of great horned owls broadcast into predominantly wooded habitat along roadside survey routes resulted in as many detections of resident red-shouldered hawks and Cooper's hawks as broadcasts of each conspecific calls.

Status, Habitat Use, and Management of Red-Shouldered Hawks in Iowa

In recent years the red-shouldered hawk (Buteo lineatus) has declined in numbers in Iowa (Brown 1964, Koenig 1975) and nationwide (Cohen 1970:14, 36; Brown 1971; Hackman and Henny 1971). In the

NEST-SITES AND HABITAT OF RED-SHOULDERED AND RED-TAILED HAWKS IN IOWA

Numerous studies have addressed the breeding biology of the Red-tailed Hawk (Buteo jam&e&s) (referred to as RTH) but only a few studies have quantified some parameters of nesting habitats of RSH and RTH, and Titus and Mosher (1981) quantitatively examined the nest-sites of four sympatric woodland hawks in the central Appalachians.
