Connecticut River Lecture Series Fall 2023

As Mother Nature lays her colorful blanket of Autumn leaves in preparation for the cold months ahead, The Roger Tory Peterson Estuary Center is once again introducing three important speakers and topics to our friends and neighbors. We invite you to join us in person for the Fall 2023 Connecticut River Lecture Series where we will focus on winged species. From where to find birds across the State, to the only flying mammal, and culminating with an exotic bird of the tropics, we are On the Wing this Fall.

Thursdays, September 21 & 28; 5:30 pm
Old Lyme

Every September near the mouth of the Connecticut River, one of the most spectacular shows in the avian world takes place. Hundreds of thousands of Tree Swallows gather right at sunset to roost in the reeds, preparing for the southbound journey in migration. The best way to see it is from a boat on the river, where you’ll be surrounded by swallows flying over the water. We’ll launch a kayak or canoe and paddle to the roosting site. Each participant must provide their own kayak or canoe and PFD.  Participants are also encouraged to bring a headlamp or light for their canoe/kayak.  Limited to 10 participants. Participants must be ages 18 and up. $25 for members/$35 for non-members

Designated as an Important Bird Area by the National Audubon Society, Mamacoke Island and the surrounding bodies of water, are home to a diverse array of bird species. Located on the Thames River, this natural area within the Connecticut College Arboretum also offers a stunning geological experience, as cliffs rise dramatically from the center of the island, and numerous geological features can be seen throughout. Join CT Audubon’s Joe Attwater as we explore the unique history of this important bird habitat, and search for birds on the river.

Webinars via Zoom


Falcons Webinar

Wednesday, October 11; 6 PM

You’re watching a small flock of shorebirds on the beach and suddenly a raptor shoots by at an incredible speed and is gone just as quickly, scattering all birds in the area. Chances are it was one of our falcons, a group of birds well known for their extreme speed. In this webinar, Conservation and Education Coordinator Joe Attwater will go over this amazing group of birds and how they live such high-speed lives. Joe will discuss:

  • Adaptations to lifestyle
  • Breeding & nesting behaviors
  • Threats & conservation
  • Species found in CT
