The Roy and Margot Larsen Sanctuary in Fairfield, Connecticut, is one of the Connecticut Audubon Society’s (CAS) most well-known destinations for birders and naturalists alike. It is a landmark location for Connecticut birding. The 184-acre sanctuary features an extensive trail system with more than seven miles of trails that cover many habitats, such as small marshes, streams, a swamp, open meadows, and forests. Nearly 200 species of birds have been observed here, including many uncommon species as well as a handful of rarities. It is an easy destination to bird, with well-marked trails; maps are available from the Connecticut Audubon Society. The CAS website has a checklist of the species that have been recorded on the property.
Larsen Sanctuary can be productive for birding in all seasons, but it is best known for spring migrants and summer breeders. The woodlands are a popular spot for many types of passerine migrants in spring. The woods surrounding the nature center and Farm Pond can hold substantial warbler flocks. Canada, Magnolia, Wilson’s, and many other species can be found there. The Chiboucas Trail loop is an easy walk on a May morning or afternoon. The Wildlife Pond often attracts passerine flocks and holds a handful of American Bitterns. The nearby meadow attracts open-habitat dwellers such as Prairie Warbler, Blue-winged Warbler, Common Yellowthroat, and Indigo Bunting.
