This species has vibrant reddish or brown patterns on its slim, greyish-white body, and a lighter colored Y- or V-shaped mark on its head.

Venomous Snakes in NY
Although uncommon, timber rattlesnake, massasauga and copperhead NY state snakes are venomous. The timber rattlesnake, which is listed as a threatened species by New York State Department of Environmental Conservation, is found mainly in the southeastern part of New York state, apart from Long Island and New York City. The massasauga, which is listed as endangered, is only ever found in large wetlands northeast of Syracuse or west of Rochester. The copperhead is most often spotted along the lower Hudson Valley, and distributed through the Catskills.
The timber rattlesnake and massasauga both have a rattle at the end of their tails, made of several hollow scales. While both species are stout, the timber rattlesnake is much longer, typically reaching a length of 6 feet compared to the massasauga's maximum of 3 feet. The timber rattlesnake has a broader head than the massasauga's and smaller scales on its crown.
The copperhead snake doesn't have a rattle, but its tail does vibrate when it is irritated. As you would expect, this species has a coppery-colored head, but the rest of its body is chestnut to dark brown with a pinkish-tan pattern. The copperhead usually grows no longer than 3 feet.
