Description and species: The Roy and Margot Larsen Wildlife Sanctuary surrounds Connecticut Audubon Society’s Center at Fairfield and is one of the largest and most widely used of our sanctuaries. Within its 155 acres it contains a great variety of habitats and wildlife. The sanctuary has seven miles of trails that include the Chiboucas wheelchair-accessible trail for the disabled. Observation platforms and bridges, interpretive signage concerning the history of the area and its flora and fauna, and an Algonquin wigwam replica all add to the experience. A brochure with a self-guided hike is available at the center, and we highly recommend you stop in to pick one up. There is a nominal admission in the form of a small donation for non-members and non-residents of Fairfield.

Hundreds of species of birds can be found within the Roy and Margot Larsen Wildlife Sanctuary. The sanctuary ponds hold a variety of ducks as they migrate south each fall and attract early spring insectivores like Eastern Phoebes and Eastern Bluebirds. A quiet mid-winter walk over the boardwalk on the streamside trail will often treat you to Winter Wren, Hermit Thrush, Brown Creeper, and many more species attracted to these warm microhabitats. Nest boxes throughout the sanctuary are utilized by many passerines as well as owls, like Eastern Screech Owls who nest in these boxes and Barred Owls who roost there during the daytime. Numerous birds can be found breeding in the Larsen Sanctuary each year and inventories and monitoring studies are ongoing.

Eastern Box Turtle

The different habitat types maintained within the sanctuary support several species that are of conservation concern, such as the Eastern Box Turtle

White-tailed Deer are frequently seen bounding through the woods. Occasionally you may see them running in the opposite direction of a Red Fox. The typical New England woodland mammals can all be found here, but one to look for in particular is the American Mink. Yes, really – you can see them here in certain areas along the main trail. Frogs, toads, salamanders, snakes and turtles are also in abundance in many spots, all the way from the farm pond near the entrance to the sanctuary to the vernal pools and damp woods on the other side of the sanctuary.

Please stop by soon whether it is for a stroll on your own, for a school field trip, or in the company of Connecticut Audubon Society staff during a guided walk or class.
