Inspired since childhood by nature and the vibrancy of her city, Leslie Day is the author of Field Guide to the Natural World of New York City, Field Guide to the Street Trees of New York City, Field Guide to the Neighborhood Birds of New York City, and Honeybee Hotel: the Waldorf Astoria Hotel’s Rooftop Garden and the Heart of New York City. She is presently working on her fifth book: River: Living on the Hudson – A Natural History, which will be published by the Cornell University Press. As a 40-year resident of the 79th Street Boat Basin, Dr. Day came to know the diversity of the city’s natural world.  Passionate about science, she earned a doctorate in science education from Columbia University and worked for decades as a science teacher. Now retired from teaching, Dr. Day spends her time writing books, giving talks on Zoom and leading nature walks throughout the city for organizations such as the New York Historical Society, garden clubs, libraries, the Washington Heights YMHA, Fort Tryon Park Trust, and the New York City Department of Parks and Recreation.
