Factors influencing nest-site selection in House Martins

Male Morphology and Nest-site Quality in House Sparrows

-Previous research on House Sparrows (Passer domesticus) in Europe indicated that males with larger bibs are more likely to obtain nest sites with multiple potential nests. To test this observation experimentally, I created nest sites containing either one or two nest boxes. 1 found no morphological differences, including bib size, between males at single-box nest sites (SBNS’s) and those at do...

Nest Site Selection by Sea Turtles

Spotted Owl Roost and Nest Site Selection in Northwestern California

We directly observed roost and nest site selection in a population of northern spotted owls (Strix occidentalis caurina) in northwestern California during 1985-89. Because of potential biases caused by use of radio telemetry in previous studies, we examined habitat use relative to habitat availability at a level not previously reported for spotted owls. Spotted owls selected coniferous forest c...

Comparing Ecological Site Descriptions to Habitat Characteristics Influencing Greater Sage-Grouse Nest Site Occurrence and Success

We used 119 greater sage-grouse (Centrocercus urophasianus) nests located in the Powder River Basin of northeastern Wyoming during 2004–2007 to assess the ability of US Department of Agriculture–Natural Resource Conservation Service (USDA–NRCS) ecological site descriptions (ESDs) to predict nest occurrence and success. We used nesting data from a regional study in the Powder River Basin that do...

Does nest-site selection influence bobwhite nesting success in’south Florida?

Context. Nest-site selection can influence nesting success, and thus population dynamics, of many species of groundnesting birds. Despite the economic importance as a game species, populations of northern bobwhites have been declining throughout the southernUnited States. This paper reports the nesting ecology of northern bobwhites (Colinus virginianus) on Babcock-Webb Wildlife Management Area,...
