Wildlife & Conservation
Pelham Bay Park is one of New York City’s Important Bird Areas. The islands and the waters around them are part of a coastal ecosystem worth protecting.
Great blue herons
The largest heron in North America, the great blue heron hunts fish in shallow water with great patience. Herons are among the birds recorded on the Chimney Sweeps Islands themselves, and they appear as a supporter on the Davis Islands coat of arms.
Double-crested cormorants
Expert divers that chase fish underwater, cormorants are often seen perched with their wings spread to dry. In Pelham Bay Park, cormorants have been recorded off the coast of Twin Island.
Coastal seabirds & migratory habitats
Gulls rest on the islands’ bare rock, while the wider park’s marshes, woodland and shoreline support a remarkable range of birds — up to 264 species have been recorded in Pelham Bay Park. In 1967 the city created the Thomas Pell Wildlife Sanctuary and the Hunter Island Marine Zoology and Geology Sanctuary, protecting 489 acres.
Rock, tide and sound
The bedrock islands and shoreline of the bay meet the tidal waters of western Long Island Sound. Rocky shores, salt marsh and open water each support different life, from shellfish and small fish to the birds that feed on them.
Enjoying the islands responsibly
The Chimney Sweeps are public parkland and a resting place for wildlife. If you visit by kayak or boat:
- Wear a life jacket and check the weather, tides and wind before setting out.
- Keep a respectful distance from resting and nesting birds; if a bird changes its behaviour, you are too close.
- Land gently, if at all, and never disturb vegetation or wildlife.
- Take every piece of litter home with you.
- Follow NYC Parks rules and U.S. Coast Guard boating guidance.
- Fly drones only where permitted, and never toward birds.
Leave the islands as you found them
The Davis Islands project exists in part to celebrate and draw attention to the natural heritage of Pelham Bay. To learn more about the park, visit NYC Parks — Pelham Bay Park.
