Chick-A-Dee Case
1. Why do black-capped chickadees produce longer “chick-a-dee” alarm call for more threatening predators? Do more intense D notes signaling caught more attention from the predators? How can this be explained by natural selection (Templeton, Greene, & Davis, 2005)?
Evidently, chickadees produce more intense “chick-a-dee” alarm call for smaller predators than larger predators. We could explore why natural selection favor this signaling behavior because producing longer D notes tend to caught more attention from the predators as well as increase the level of exposure under threat. In this way, we can understand how chickadees balance benefit and risk ratio between recruiting other birds for help while increasing their conspicuousness and exposure
