Avian nest predation: relationships with landscape characteristics and influences on adult and nestling behavior.
… remain in our understanding of how birds respond behaviorally to information regarding predation risk. My research sought to address the following: (1) is the relationship between predator-specific nest predation and landscape composition dependent on the spatial scale at which it is examined, (2) …

Variation in mass and wing loading of nestling American Kestrels: possible effects of nestling behavior and adult provisioning behavior
… (i.e. aerial insectivores), it is important that nestlings not gain excess weight. Nestlings in some species must attain an efficient wing loading just prior to fledging to facilitate mobility for hunting and evading predators. My objective was to examine the mass of nestling American Kestrels …

Factors influencing pre-fledging mass recession of nestling Tree Swallows
… contributing to pre-fledging mass recession by nestling Tree Swallows (Tachycineta bicolor). My study was conducted during the 2015 breeding season at the Blue Grass Army Depot in Madison County, Kentucky. Nestling Tree Swallows (n = 127) in 29 broods were divided into half-weighted (n = 32), …

Effect of variation in nestling hunger levels on the begging behavior of nestlings and the provisioning behavior of adult American Kestrels
<p>Little is known about how variation in nestling begging intensity influences the behavior of adult raptors and how responses of adult males and females to such variation might differ. My objective was to manipulate the begging intensity of nestling American Kestrels (Falco sparverius) and …

Facultative adjustment of pre-fledging mass recession by nestling Chimney Swifts (Chaetura pelagica)
… mass recession is a crucial aspect of the nestling period, ensuring fledglings will have an appropriate wing loading. My objectives were to determine if mass recession by Chimney Swift <em>(Chaetura pelagica)</em> nestlings is intrinsically controlled or facultatively adjusted by nestlings, …

Perceived Predation Risk And The Responses Of Adult And Nestling Tree Swallows (tachycineta Bicolor)
… are functionally referential and provide their nestlings with information about the level of threat predators may pose. Although several investigators have examined the responses of nestlings of species with open-cup nests to the anti-predator calls of adults, few have conducted such studies …
