Nest-site selection by Sharp-shinned Hawks in Kentucky
… breeding biology, including their preferred nesting habitat. In 2009 and 2010, I searched 248 forest stands in Kentucky and found 11 nests, all located in pines (Pinus spp.). Nests were at a mean height of 18.6 ± 1.4 m in trees with a mean height of 23.7 m and mean dbh of 38.2 cm. Nests were …

Burrowing Owl Distribution and Nest Site Selection in Western South Dakota
… west of the Missouri River, where it usually nests in black-tailed prairie dog (Cynomys ludovicianus) colonies. Information about the burrowing owl’s current range and habitat needs in South Dakota is necessary to maintain the species as a relatively common component of the state’s avifauna. …

Behavior, Nest Site Selection and Success of Black Terns (Chlidonias niger)
… of which are still largely unknown. I monitored nest success and wetland use by Black Terns in three colony sites in northern Michigan throughout 2017 and 2018 and used traditional survey methods coupled with nest cameras to document Black Tern nest success and mortality events. Colony sites …

Nest site selection by common eiders : relationships with habitat features, microclimate and incubation success
… failed to look for evidence of processes shaping nest site selection patterns. Furthermore, little is known about adaptive nest site selection in northern environments where habitats often have little vegetation and time and climatic constraints may be pronounced. Therefore, I investigated …

Factors affecting piping plover (Charadrius melodus) nest site selection following landscape and predator community changes
… and human interventions significantly impact nesting habitat use by species like the piping plover (Charadrius melodus) along Atlantic coastlines. Our study focused on Fire Island, New York, assessing changes in vegetation succession, plover nesting habitat selection, and suitable nesting …

Nest-site resources for cavity-nesting birds in the southern Allegheny Mountain forests of West Virginia
Cavity-nesting birds may be negatively impacted by a lack of proper nesting sites. Southern Allegheny Mountain forests of West Virginia are unique due to the juxtaposition and diversity of forest cover types. Management must focus on monitoring wildlife population levels as well as habitat …

Four-Toed Salamander (hemidactylium Scutatum) Nest Site Characteristics In Natural And Constructed Wetlands In Eastern Kentucky
… salamander (<em>Hemidactylium scutatum</em>) nesting ecology and nest-site characteristics and to determine if these differ between natural and constructed wetlands. Another objective was to add to our knowledge of the natural history of the species in Kentucky. Six natural and six constructed …

Gopher tortoise nest-site selection at burrows and the influence of nest environment on hatching success
Nesting and early life is a period of high mortality for many turtle species, so understanding how turtles select nest sites, and how those nest sites impact hatching success, may be important for successful species conservation. In this research, my objective was to 1) understand how the …

On the nest site characteristics of the 'dusky' orange-crowned warbler (Vermivora celata sordida) endemic to Santa Catalina Island
This study focuses on the nest site of a poorly known endemic subspecies of orange-crowned warbler (Vermivora celata sordida). The research took place during 2006 on Santa Catalina Island, part of the Channel Island archipelago in Southern California. As one of the first detailed descriptions of …

Nest-site selection, nocturnal nest desertion, and productivity in a common tern (<i>sterna hirundo</i>) colony at Detroit River, Michigan
… that of eastern North America. On an artificial site, I studied the substrate and vegetation preference and productivity of nesting terns at two scales: general habitat and nest-site. Terns nested later and less successfully in large river rock (13 to 25-cm diameter) compared to more diverse …

Northern pintail nest site selection, nest success, renesting ecology and survival in the intensively farmed prairies of southern Saskatchewan: an evaluation of the ecological trap hypothesis
Unlike most prairie nesting ducks (Anas spp.), the North American population of northern pintails (A. acuta, hereafter pintails) has failed to respond as expected to improved wetland conditions on the U.S. and Canadian prairies during the mid to late 1990s. My primary objectives were to test the …
