Search for Winter Flocks

Description

As temperatures drop and resources grow scarce, the birds of North River start moving together. Watching that happen is one of winter's quieter pleasures.

On this morning walk, a naturalist guides you along the river and sanctuary trails to observe mixed-species winter flocks: chickadees, goldfinches, sparrows, and other species that band together for warmth and protection this time of year.

You'll build an understanding of winter ecology, learning how birds adapt their foraging, communication, and social behavior when the landscape shifts.

Perfect for beginners and intermediate birders alike.

Checking registration status.
