The Meaning Of Song Type: Exploring Behavioral Responses Of Field Sparrows To Three Simple Song Types, Eliza Foli
Honors Theses
The frequency, rate, and overall quality of a male’s song may indicate the singer’s physical quality, either as a threat or as a potential mate, and are used for species recognition. However, the degree to which a song must differ acoustically to communicate different information about the singer remains unclear. Analysis of male field sparrow simple song recorded in southwest Michigan revealed three structurally distinct clusters of simple song that differ in frequency characteristics. We hypothesize that songs in each cluster convey information about the singer and that receivers respond more strongly to songs more similar to their own song. …

Seabirds are marine top predators, and as such are often studied as bioindicators of climate shifts (Oswald and Arnold 2012). Though many studies have analyzed the effect of macroclimatic variation on marine prey species availability and thus seabirds, few have analyzed effects of microclimate - fine spatial patterns of climate (Mantua and Hare 2002; Hatch 2013; Kim and Monaghan 2005a). I tested the hypothesis that localized temperature and humidity at nest sites interact with food availability to alter black-legged kittiwake (Rissa tridactyla) nest site quality, chick body condition during growth and development, and reproductive parameters including Julian lay …
