tens of thousands of birds congregate in the lower Connecticut River Valley on their migration route south. One flock of birds, primarily comprised of tree swallows, come each evening to an island to roost. As many as half a million may come in at dusk where they converge just before sunset over the island, often creating a spectacular “ballet” in the sky and eventually forming a “funnel” or "rain". Then, just after sunset, they settle down into a communal roost in the phragmites (a type of reed) for the night.We will educate you on this phenomenon, answer questions and point out other migrating birds or local wildlife we may see. Bring a picnic basket, your favorite beverage and your binoculars (we have a limited supply on board to loan for the cruise) and enjoy the evening as we wait for the Tree Swallow spectacle. Please no children under 10 years old. This cruise is approximately three hours in length. Online booking at www.ctriverquest.com.
