Connecticut DEP’s Wildlife Division publishes a list of Endangered and Threatened Species, which includes mammals, birds, reptiles, amphibians, fish, and invertebrates. Their bird list is presented below in the format of the Sherwood Island checklist, which includes most of the Endangered and Threatened Species. For each of the listed birds, DEP provides fact sheets.
In the table below, “Status” refers to Endangered (E), Threatened (T), or Special Concern (SC). For species sighted in the park during the 2002-2003 Fall-Winter season, links are provided to the sightings reports and/or photographs.
The Willet, listed as a Species of Special Concern, was an occasional visitor to the park until 1997. Since then one to three pairs have nested each year. The birds arrive in late April or early May and leave in August.
