Bird-a-thon Along the Charles River

Mass Audubon's largest statewide event of the year, Bird-a-thon, provides the perfect opportunity to observe migrant bird species that are passing through the neighborhood. We will travel approximately 1-1.5 miles on gravel paths and grassy fields along the Charles River stopping frequently to observe the birds we find in the water, hiding on the riverbank, and soaring above.

Co-led with the Brookline Bird Club.
