The detailed records of bird sightings and phenological observations around Concord from the last 170 years—from Thoreau’s notes to today’s studies by scientists at Boston University—provide a key to studying how climate change is affecting bird migration. Boston University professor Richard Primack and Colby College visiting assistant professor Amanda Gallinat present their recent research and unexpected new findings from eBird data collected in Concord.

Following their presentation, Professors Primack and Gallinat will be joined in conversation by a panel of ornithologists.

Tickets are free for Concord Museum and Mass Audubon members.

This event is co-sponsored by Mass. Audubon.
