We are seeking a PhD student to develop and conduct a dissertation research project that fits within our on-going long-term study on the breeding biology of black-throated blue warblers, including the effects of a changing environment on breeding behavior (https://nationalzoo.si.edu/migratory-birds/climate-change-hubbard-brook-forest) as well as other topics on the behavioral ecology of these birds. The successful applicant will join the graduate program in the Field of Neurobiology and Behavior at Cornell University (http://nbb.cornell.edu), and will also be affiliated with the Cornell Lab of Ornithology (http://www.birds.cornell.edu/Page.aspx?pid=1478), and also will have strong ties to the Smithsonian Migratory Bird Center (https://nationalzoo.si.edu/migratory-birds). The specific dissertation project will be developed by the student in collaboration with the project PI’s, Mike Webster (http://pages.nbb.cornell.edu/neurobio/websterlab/index.html) and Scott Sillett (https://nationalzoo.si.edu/conservation/t-scott-sillett). Possible research topics include the behavioral responses of migratory birds to environmental variation, parental care and fledgling behavior, and carry-over effects of winter conditions on breeding behavior and sexual signals. Research will be conducted, at least in part, at the Hubbard Brook Experimental Forest (https://hubbardbrook.org). For more information, contact Mike Webster (firstname.lastname@example.org).
