Ithaca, NY 14853

Prof. Vehrencamp also maintains an emeritus professor appointment at the Laboratory of Ornithology, Bioacoustics Research Programhttps://www.allaboutbirds.org/sounding-out-the-dawn-chorus-of-banded-wrens-in-costa-rica/

Research Interests

My recent research efforts have focused on the evolution of animal communication systems in birds. Using techniques such as interactive song playback, multi-microphone array recording, and sound synthesis, students are studying the function and meaning of complex singing behavior in wren, sparrow, and mockingbird species with repertoires of song types. We are also investigating the role of song learning strategies in different species that result in different levels of song-type sharing among males and the ability to use song-type matching as a threat signal. Past projects include: 1) the evolution of cooperative breeding in birds, particularly in the factors that promote low-skew or joint-nesting breeding systems; 2) the energetic costs of signaling; and 3) the ecological determinants of group size.

Dr. Vehrencamp retired as of Fall 2010 and is no longer taking new graduate students.
