Playbacks as a Tool for Management and Understanding Relationship Dynamics
Playbacks as a Tool for Management and Understanding Relationship Dynamics
I completed a post-bac position with Dr. Elizabeth Hobson in 2021 where I led a vocalization and playback project within her monk parakeet system. I'm primarily interested in (1) how we can use playbacks to assist in the management of their populations, (2) understanding how their global distribution has influenced their vocalizations, and (3) exploring how we can use playbacks to learn more about an individual's social connections and memory.
Other publications from the monk parakeet system can be viewed on the Hobson Lab website.

Species Management
Utilizing animal behavior for conservation and wildlife management is becoming more popular due it's low cost, low risk, and high effectiveness. Vocalizations are a popular form of communication and is a conspicuous behavior that can result in an array of behaviors. We are interested in learning what vocalizations work best for controlling the monk parakeet populations.
This work was published in Animal Behavior & Cognition, read it here: Estien et al. (2022) Temporary behavioral responses to playbacks by pest parrots and implications for management. https://doi.org/10.26451/abc.09.04.01.2022 |
Understanding Vocal Variation
Much like humans, animals can form variations in their vocalizations. These variations can be tied to geographic locations and/or environmental pressures and can vary within and across land masses. We are interested in doing a direct comparison across multiple populations to further our understanding of the pressures that select for and maintain these variations in vocalization.

Social Affiliation and Competency
Social relationships with conspecifics can provide many benefits, but the strength of relationships can fluctuate over time in response to previous interactions and current group dynamics. Being able to categorize these affiliative relationships by strength or importance could help individuals better prioritize social investments that affect the formation or persistence of social connections. However, we still do not have a general understanding of when these shifts in the salience of dyadic relationships occur or how to detect these across species. We are interested in combining field methods and observational data to better understand relationship salience, memory, and plasticity.
The preliminary results of this work was presented at ABS 2022 as a lightning talk! The title of the talk was: "Playback Responses as a Tool to Understand Relationship Dynamics" and you can view the slides here. |
