NEW! Grasses: An Introduction to Identification With Lauren Brown

Saturday, June 25; 9 am – 1 pm
RTP Estuary Center

Grasses are all around us – along roadsides and riverbanks, in fields and marshes – but many people are scared to try identifying them, thinking that “they all look alike” and that their identification requires a specialized vocabulary and a microscope. Not so!  Lauren Brown,
co-author with Ted Elliman of Grasses, Sedges, Rushes: An Identification Guide, will show you how to tell one species from another using naked-eye characteristics and plain English.  We will start with study in the classroom and then proceed to a riverfront property for identification in the field.  It will be very useful for you to bring this book, or its predecessor, Grasses: An Identification Guide by Lauren Brown. Participants will need transportation to proceed to the outdoor portion of the program. Registration required, 12 person capacity. $40 members; $60 for non-members.

Bird Walks

Bird Walks at the RTP Estuary Center

Follow the progress of bird migration at our new sanctuary in Old Lyme this spring, and help us collect valuable bird data in the process. Because the RTP Estuary Center is a new sanctuary, you’ll be helping establish a baseline record of the birds that migrate through.

The data will prove valuable as we work to make the sanctuary better for birds.

Each walk starts at 9 am. Click the dates to sign up!

Thursday, June 2 – Register here
Thursday, June 16 – Register here

The cost is $5 per walk for Connecticut Audubon members; $10 for non members.


Shorebird Walks

These birds compete for space with beach goers and shoreline development, and as a result, are often of conservation concern. Join us as we look for many of our shorebird species at some of the best spots around southeastern Connecticut, and learn how you can help these charasmatic birds. $10 for members; $15 for non-members.
