Andrew Farnsworth

Andrew Farnsworth (Cornell Ph.D. student) studies flight calls of migrating birds. These vocalizations are short in duration, variable in frequency, species-specific, and primarily nocturnal. As part of a larger study of the function of flight calls and flight calling behavior, Andrew is using a phylogeny of wood-warblers (family Parulidae) reconstructed from mitochondrial and nuclear DNA to study what factors (e.g., body mass) might drive the variation in flight calls (e.g., frequency) among different species.
