My field-based research program offers undergraduates opportunities for independent research and field training in avian biology in New Hampshire and the Caribbean Islands
Sara Kaiser, PI
As a Research Ecologist at the Cornell Lab of Ornithology, I direct a year-long research and training program that I developed to provide undergraduates an entry point into field ornithology at the Hubbard Brook Experimental Forest in the White Mountains of New Hampshire. I also teach the Field Methods in Avian Ecology course each Fall. My research program offers additional, training opportunities in the Caribbean Islands and locally in central New York at a migration banding station that I will establish (COMING SOON!). I encourage my students to develop original research leading to senior theses and peer-reviewed scientific publications to further their development as scholars.
My highly motivated students have developed original research on a variety of topics, including offspring sex allocation, perceived predation risk "fear effects", research disturbance, artificial light at night, climate change, animal personality, sexual signals, vocal communication, female plumage variation, mate choice, extra-pair mating, parental behavior, nest predation, habitat selection, nest construction, malaria prevalence, molecular diet analysis, and population genetic structure. Student projects have been based in the field, lab, and/or data-driven by leveraging data (behavioral, genetic, environmental) collected as part of ongoing, long-term research projects.

Senior project: Conservation genetics of Grasshopper Sparrows (Ammodramus savannarum) 

Skewed adult sex ratios can exacerbate population declines by limiting the ability of individuals to find mates and reproduce in monogamous species. My research examines the association between the sex ratio of nestlings and adults in a small, declining population of Grasshopper Sparrows at the Chester River Field Research Station in Maryland. I am using genetic techniques to determine the sex from nestling blood samples collected from 2005-2009 and examining demographic and environmental factors affecting changes in adult sex ratios from 1999-2014.

Jasmine (Jazzy), Lab Pooch
I am an avid birder, runner, swimmer, and boater. I get along with every dog, cat, and person (big or small) that I meet. I am anxious to explore the White Mountain National Forest and entertain the Hubbard Brook research community and swim in Mirror Lake once this pandemic is behind us.
