Deer & Wildlife
Heckscher State Park is known for its white-tailed deer: the Friends of Heckscher State Park call it the "Home of the White-Tailed Deer," and NYS Parks says visitors see whitetail deer, "a variety of birds and other wildlife" alongside the views of the Great South Bay. The fields and woods' edges inside the parkway loop are the places to look. Watch from a distance, never feed them, and check for ticks after any walk in the grass or woods.
Wildlife at a Glance
Where the Wildlife Is
The Friends of Heckscher State Park describe woodlands, wetlands and shoreline that "support hundreds of bird species." The state's 2023 site map shows the habitats clearly: woods across the north and west of the park, a large wetland and several small ponds inside the parkway loop, open fields around the picnic areas, and beach and marsh edge along the Great South Bay and Nicoll's Bay.
White-Tailed Deer
Deer are the animal most visitors remember. Look for them in the fields around the picnic groves and at the woods' edge, and watch for them crossing the park roads: drive slowly on the Heckscher State Parkway loop.
What to do when you see deer:
- Stay back and let them move off on their own.
- Do not feed them or leave food out.
- Keep dogs on their six-foot leash; NYS Parks' dog rules say not to let a dog chase or harm wildlife. Dogs are only allowed in the west woods anyway (dogs).
Birds
The bay shore, wetlands and woods draw birds year-round. NYS Parks runs a public Citizen Science Bird Count at Heckscher; in 2026 it was on December 19, with reservations on Eventbrite. Bring binoculars, as the state suggests. Nicoll's Bay and the Greenbelt Trail on the east side make an easy birding walk (hiking).
Nature Programs
NYS Parks' Long Island Environmental Interpretive Center, based at Connetquot River State Park Preserve, runs programs at parks across the region. Heckscher events in late 2026 included a Sensory Scavenger Hunt on November 27 and the December bird count, both booked on Eventbrite. Schools and scout groups can book programs through the center.
Ticks
NYS Parks' Long Island guide names three ticks to watch for:
- Black-legged (deer) tick: 1 to 2 mm; common in woods inhabited by deer; can carry Lyme disease, babesiosis and tularemia.
- Lone star tick: 4 to 6 mm; in medium to tall grass in wooded areas and on dunes.
- American dog tick: 4 to 6 mm; in grass, brush and overgrown fields near woods.
Ticks climb vegetation from about 6 inches to 2 feet and wait to brush onto a passer-by. Check yourself, children and pets after every visit.
Wildlife Rules
- Do not disturb, feed or harm animals or damage plants; state park rules forbid injuring "any tree or other plant life."
- Do not bring animals into the park except a leashed dog in the permitted area.
- Stay on established trails and roads.
