Eliza Wein
2025 Research and Stewardship Intern
Eliza recently graduated from Cornell University with a B.S. in Environment and Sustainability. She is a lifelong nature enthusiast, with a particular interest in birds, and worked on several bird studies with the Cornell Lab of Ornithology during her time in college. She has also done field work on birds in Wyoming and Ecuador. At Great Hollow, Eliza is assisting with our research on the responses of plants, insects, birds, and bats to forest management practices that are intended to benefit the New England cottontail. Eliza hopes to attend graduate school, with a focus on birds, and is interning at Great Hollow to help prepare her for her future graduate studies and career.
