Introduction to Summer 2017
This summer of 2017 I am studying changes in song and cultural evolution over time in the Mourning Warbler. This study involves 1) recording 2017 songs from breeding males, 2) playback experiments measuring the aggressive responses of males to historical songs from my 1988 recordings versus songs of current breeding males. My study will focus on whether and how the songs have changed over time. The playback experiments are designed to test whether the historical songs still elicit aggressive responses by males or whether the historical songs have lost their signal efficacy. I will begin in Wreck Cove, Nova Scotia and then travel to the west coast of Newfoundland. This blog will contain updates from this field work and daylists of birds during the trip.
