Graduate Student Theses, Dissertations, & Professional Papers
To avoid predation, many animals have evolved complex systems of anti-predator communication. Alarm calls are a key component of anti-predator behavior in many birds, and can provide detailed information about predators. Additionally, many birds and mammals produce and respond to each other’s alarm calls, creating a complex communication network. Furthermore, individuals may give alarm calls in response to the alarm calls of others nearby, without actually seeing a predator. This makes possible the spatial spread of alarm information, which can result in complex communication networks extending over a large area. However, this requires suitable habitat in which birds will be …
Vocal Responses Of Adult Eastern Bluebirds (Sialia Sialis) To Potential Nest Predators And The Behavioral Responses Of Nestlings, Erin E. Grabarczyk
Vocal Responses Of Adult Eastern Bluebirds (Sialia Sialis) To Potential Nest Predators And The Behavioral Responses Of Nestlings, Erin E. Grabarczyk
Online Theses and Dissertations
The alarm calls of some birds 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 cavity-nesting Eastern Bluebirds (Sialia sialis) were to examine (1) the vocal responses of adult Eastern Bluebirds to different predators, and (2) the behavioral responses of nestlings to those adult vocalizations. My study was conducted from April - July 2013 at the Blue Grass Army Depot in Madison County, Kentucky. Pairs of Eastern Bluebirds …
