Foraging habitat niche comparisons and foraging behavior of seven species of flycatchers in southwest Virginia
Foraging habitats and foraging behavior for seven species of Tyrannid flycatchers were measured to examine interspecific habitat resource partitioning, niche breadth and niche overlap. Four of the species inhabited forested areas; Great Crested Flycatcher, Eastern Wood Pewee, Least Flycatcher and …

Foraging Habitat and Reproductive Success of Red-Cockaded Woodpecker (<em>Picoides borealis</em>) Groups in Southeastern Georgia
<p>The maintenance of adequate, high-quality foraging habitat is crucial to the recovery of populations of the federally endangered Red-cockaded Woodpecker (.Picoides borealis). The Technical/Agency Draft Revised Recovery Plan for the Redcockaded Woodpecker (Picoides borealis) (USFWS 2000) sets the …

The influence of foraging habitat on acoustic signal source levels in two bat species, Neoromicia capensis (Vespertilionidae) and Tadarida aegyptiaca (Molossidae)
… range is likely to vary with body size and foraging habitat because these determine the operational range needed by the bat. This study thus attempted to answer the following questions; (1) is the source levels of animal acoustic signals different in different situations? (2) Does body size …

Piping plover breeding biology and reproductive success on Assateague Island
… determined by the distribution of three types of foraging habitats: bayside mud and sand flats, saltwater pools formed by storm tides, and a drawn down waterfowl impoundment. Reproductive rates were lower than two recent estimates of the level necessary to maintain a stable population. The primary …

Target strength of bat prey in relation to pulse frequency and vegetation density in bat species, Rhinolophus fumigatus (Rüppell's horseshoe bat)
… predicted by its body size (12.7 ± 0.9 g). The foraging habitat hypothesis states that a deviation from the allometric relationship between pulse frequency and body size is related to the foraging habitat and foraging style of the species and predicts a negative relationship between peak …

Seabird foraging in dynamic oceanographic features
… eddies, and upwellings, provide important foraging areas for marine predators. These areas serve as important "hotspots" of marine life, by aggregating weakly swimming lower and mid-trophic level species which, in turn, attract foraging predators. Despite the importance of these dynamic …

Bats and trees in a managed forest
… species rely heavily on forests for roosting and foraging habitat. Especially in the face of drastic population declines, understanding how forests can be managed to support local bat assemblages is crucial for bat conservation. We worked in two managed hardwood state forests in southern Indiana …

The conservation ecology of the European nightjar (Caprimulgus europaeus) in a complex heathland-plantation landscape.
… song territories, highlighting the importance of foraging habitat in the broader landscape. Compositional analysis showed that foraging nightjars selected open canopy plantation forest (aged 5-10 years) and newly planted coupes (aged 0-4 years), with grazed grass-heath also used when available …

The influence of woodlot size and location in suburban and rural matrices on bird species richness and individual abundance
… larger woodlots. Tufted Titmouse may exploit the habitat structure of smaller woodlots in fragmented landscapes to increase access to foraging habitat. Conservation strategies that reduce fragmentation and promote greater habitat diversity may lead to greater bird species diversity and …

Bats of the Monongahela National Forest
… years. Insight into their distributions and habitat associations, as well as understanding population trends, will aid in conservation efforts. In this study, the geographic distributions of the 10 species of bats found in the Monongahela National Forest of West Virginia were analyzed, using …

Spatial ecology informs reintroduction tactics for warabin (Burhinus grallarius;bush stone-curlew)

Molecular phylogenetics and the evolution of high-frequency echolocation in horseshoe bats (Genus Rhinolophus)
… Hypothesis - selection pressures linked to habitat structure have shaped the evolution of high-frequency echolocation calls; (4) The Foraging Habitat Hypothesis - foraging style and habitat of a bat should correspond to echolocation call frequency and wing design; and (5) The Acoustic …

Re-Establishing Bald Eagle and Osprey Breeding Populations in South Dakota Through Hacking: A Feasibility Study

Migrant Shorebird, Breeding Waterfowl, and Invertebrate Reponse to Conditions in Temporary Wetlands in Easter Central South Dakota During Spring

These results suggest that habitat conditions rather than tillage or grazing practice determine whether shorebirds or waterfowl use temporary wetlands. Using sweep and core samples, numerous and …

Nest-site selection by Sharp-shinned Hawks in Kentucky
