Grade and Sieving (2016) investigated the inter-species impacts of eavesdropping on other species calls when exposed to noise pollution, and used alarm calls of tufted titmice, which are similar to chickadees in mobbing behavior. They found that there was a high correlation between noise pollution and inability to detect alarm calls of titmice, suggesting that highways have significant impacts on cardinal, and possibly other passerine survival. Interestingly enough, titmice “Z calls” used to deter predation are similar in frequency and sonographic structure to that of black-capped chickadee mobbing calls, which could provide insights on impacts of similar alarm calls on noise. Our study unwraps this question to explore the intra-species impacts of noise on mobbing behavior. We chose to focus on the black-capped chickadee, since this species is easily identifiable, common, and is incredibly responsive to mobbing behavior. We created a traditional playback experiment to test for the impacts of intra-species communication through mobbing calls in sites with high and low background noise.
