Per the Cornell website: "Whether wheeling over a swamp forest or whistling plaintively from a riverine park, a Red-shouldered Hawk is typically a sign of tall woods and water. It’s one of our most distinctively marked common hawks, with barred reddish-peachy underparts and a strongly banded tail. In flight, translucent crescents near the wingtips help to identify the species at a distance. These forest hawks hunt prey ranging from mice to frogs and snakes."
Here is a photo from Greenfield Lake where they nest regularly.
