What Relationships Do Similar Tamarin Species Have With Each Other?: Alarm Call Anti-Predator Responses

Methods

Summary

This study will use behavioral data collection to identify the similarities in anti-predator response based on different species' calls. The behavioral distinctions will be determined using an ethogram during behavioral study research (below). The study will use playbacks of alarm calls from Emperor and Saddleback tamarins in an attempt to elicit a reaction. Determining the reaction of tamarins to each playback call will show the relationship to the caller. 

Challenges

One of the challenges I will face is due to the fact that I will be studying wild primates. Wild primates are free-range and able to move as they wish. The ability to collect data on them depends on easily locating them and keeping with them for the research days. An extended time in the jungle should give me enough time to collect data. 

Pre Analysis Plan

 The hypothesis I will test is whether tamarins respond to heterospecific calls similarly to conspecific call reactions. Predictions stemming from the hypothesis include (1) monkeys’ vigilance behavior will increase in response to both conspecific and heterospecific alarm calls, (2) monkeys will respond to both heterospecific and conspecific alarm calls with alarm calls, and (3) monkeys will move away from the location of both conspecific and heterospecific monkeys’ alarm calls, presumably to reduce the possibility of predation.
