Handling the heat: managing microclimates for nesting desert hornbills
… the impact of high air temperatures on hornbill nest success is mediated mostly (70%) through direct negative effects of high nest temperatures on chick growth. To address this, I tested whether an insulated nest box design could buffer negative effects of high air temperatures and improve …

Understanding Behavior and Nest Box Usage in Three Species of Owl Monkeys: Azara's Owl Monkey (Aotus azarai), Spix's Owl Monkey (A. Vociferans) and Nancy's Owl Monkey (A. Nancymaae)
The use of tree holes and nest building behavior is uncommon among most primate species. In research facilities that house species requiring nesting sites, such as those that use tree holes in the wild, providing nest boxes is crucial to their psychological well-being. The goal of this study was to …

Factors Associated with Space Use and Reproductive Success of American Kestrels in Northern Virginia, USA
… female = 42) in northern Virginia and monitored nesting attempts (n = 48) for reproductive outcomes. Mean range size across stages during the breeding season (incubation, nestling, fledgling, post-breeding, and shifted post-breeding) was 0.51 km² (95% CI: 0.42 – 0.61, range 0.01 km²–4.27 km²), …

Efficacy of Nest Boxes for Wild Bumblebees as a Supplemental Pollination Strategy in Highbush Blueberry
… spp. L) are better suited. Studies on the use of nest boxes to augment wild bumblebee populations are limited and have focused solely on nest box occupation, without determining whether there is any subsequent increase in bumblebee visitation to flowers in the field. This two-year study evaluated …

Natal dispersal and first-year survival in a neotropical migratory songbird
… Warblers (Protonotaria citrea) breeding within a nest box study system covering a large area. Surveys outside the nest box study system (up to 30 km in all directions) supported the legitimacy of the dispersal pattern calculated from the nest box study. By incorporating natal dispersal distance …

Reproductive Success of American Kestrels (<em>Falco sparverius</em>) Nesting in Boxes along an Interstate in Northeastern Tennessee.
<p>Nest box programs provide supplemental nest sites for American Kestrels, <em>Falco sparverius</em>. When the availability of nest sites is a limiting factor, the addition of nest boxes can increase local breeding populations. These programs also facilitate the collection of data on breeding …

Honey Bee (Apis Mellifera) Foraging Preferences are Negatively Correlated with Alfalfa Leafcutting Bee (Megachile Rotundata) Productivity in Virginian Landscapes
… are managed, polylectic, solitary, cavity-nesting bees that are widely naturalized in North America. We selected M. rotundata as a model organism to validate the honey bee foraging data because they share some characteristics with other cavity nesting wild bees, but they are a tractable …

Wood Duck Brood Movements, Habitat Use, and Survival Rates on Two Prairie Rivers in South Dakota
… and survival were studied by radio-marking hens nesting in boxes on the Big Sioux River, 1992-1994, and Maple River, 1993-1994, in South Dakota. The Big Sioux River is a lower perennial stream bordered by a narrow wooded corridor and a fairly wide floodplain. The surrounding area has a well …

Wood Duck Use and Nesting Success in Artificial Nesting Structures in Eastern South Dakota
Wood duck (Aix sponsa) nest boxes in eastern South Dakota were examined for use by wood ducks and competing species in 1991 (n=506) and 1992 (n=669). Nest box composition in 1991 was: 331 plastic double-walled (POW), 11 plastic single-walled (PSW), and 154 wooden nesting structures; in 1992, 382 of …

Reproductive success of a generalist brood parasite predicts the rate of parasitism in the subsequent year
… likelihood of cowbird parasitism, we examined nesting data for a highly suitable host, the prothonotary warbler (Protonotaria citrea). We recorded parasitism status (yes or no), number of cowbird eggs, and the number of host and cowbird fledglings for 3848 warbler nests from 1994-2010 in …

The nest defense and nest-destroying behaviors of house wrens
Presentations of three potential nest intruders were used to investigate house wren nest defense behavior, while regular nest box checks provided information regarding house wren nest-destroying behavior. During nest defense trials, male wrens were typically more active in defense than females in …

Factors impacting the breeding success of African penguins Spheniscus demersus on Robben Island
… onset of breeding and the suitability of various nest types to mitigate changing climatic conditions. Body mass was measured by recording weights using an automated weighing scale set up in front of a nest. Weights were taken at the start of breeding of each penguin in a breeding pair and these …

Behavioral ecology of juvenile brown-headed cowbirds: implications for the evolution and maintenance of avian brood parasitism
… a prothonotary warbler (Protonotaria citrea) nest box dataset, comprising 21 years (1994-2014), to demonstrate that fledgling cowbirds provide reliable information indicating host quality that is used in future egg-laying decisions of adult female cowbirds. Both site-wide cowbird productivity …

Vocal responses of adult Eastern Bluebirds (Sialia sialis) to potential nest predators and the behavioral responses of nestlings
… are functionally referential and may provide nestlings with information about the threat posed by potential predators. However, few investigators have examined the responses of nestlings in cavity nests to the anti-predator vocalizations of adults. Therefore, the objectives of my study of …

Conserving a charismatic grassland species in Illinois: the barn owl
… barn owls both suitable foraging habitat and nest sites. To mitigate this loss and support barn owl populations, many states, including Illinois, have installed nest boxes in or near grassland habitat. Many of these boxes were never monitored to document their success. Adding to the …
