Indirect effects of a competitor on life history and reproductive traits in a cavity nesting bird 2018 496 Research on life history evolution in birds has revealed both direct and indirect effects of predation. Increased levels of nest predation favor reproductive behaviors that reduce the threat of predators on offspring or allow parents to bet hedge for...
Trilled song types are more salient than non-trilled song types in agonistic interactions between male song sparrows (Melospiza Melodia) 2017 800 Most research on song complexity has mainly focused on repertoire size. However, the way various song structures within a repertoire function in male-male interactions is less well understood. In this study, I have explored the functional significanc...
Telomere length as a biomarker for stress in Eastern bluebird nestlings (Sialia sialis) reared in urban habitats 2018 642 Eastern bluebirds (Sialia sialis) are often found in urban areas and have seemingly adapted to the changing conditions, however, an often-overlooked potential threat for urban dwellers is anthropogenic stress or human-induced environmental stressors....
Investigating vocal plasticity in song sparrows (Melospizia melodia) as a mechanism to avoid masking noise in urban environments 2023 17 Animals that successfully colonize urban areas must be tolerant of anthropogenic disturbance including noise. Chronic anthropogenic noise may be difficult for animals that use acoustic signals to overcome if it disrupts communication. Most anthropoge...
The effect of parenting styles and biparental cooperation on reproductive success in the Carolina Chickadee (Poecile carolinensis) 2020 287 Socially monogamous birds use biparental care to off-set the high cost of energy, resources, andtime needed to successfully rear their offspring. To be effective, biparental care requirescooperation between the parents. While parental effort and task...
