The Linnaean Society of New York

The Linnaean Society of New York Calendar

The Linnaean Society of New York presents programs on natural history topics monthly from September through May, except March. You are invited to attend in person or online via Zoom. Our meetings are open to the public and free of charge.

Throughout the year, we offer up to one hundred field trips and other events led by passionate volunteer naturalists. Our core emphasis is on the avian world, but our field trips embrace the interests of plant, bat, dragonfly, and butterfly enthusiasts.
