Each spring, endangered Piping Plovers and Least Terns return to nest and raise their young on southern Maine beaches. For more than 35 years, Maine Audubon and our partners have worked with local residents, landowners, and visitors to ensure that endangered birds, wildlife, and people can safely share the beach.
Piping Plovers and Least Terns need sandy beaches in order to nest and raise their young. Of course, people also love to live near and visit the beach. Over time, the development and construction of seawalls, jetties, piers, homes, parking lots, and other structures has significantly reduced the available shoreline habitat for these two species of birds.
The increase in Maine’s beachfront population has also brought more people and their pets to nesting beaches. This can keep adult plovers from tending to their eggs and chicks, which leaves the nests vulnerable to predators and the elements.

Facts about Piping Plovers and Least Terns
Lots of great information about these birds is available in our Piping Plover & Least Tern Information Sheet (pdf).
- Plovers and terns lay their eggs directly on the sand. The eggs (and chicks) are sand-colored, and can can be extremely difficult to see.
- When an adult Piping Plover perceives that a predator is threatening its nest, the bird will attempt to distract it by moving a few feet away, pretending to have a broken wing, and sounding a distress call. Even if this ruse works, the adult bird’s absence leaves the eggs or chicks vulnerable to the elements.
- When a plover chick feels threatened, it will freeze in the hope of being overlooked. Sometimes people mistake this for an injury and pick the chick up, which puts the chick at risk of injury or injury or even death.
- Chicks regularly move up and down the beach in search of food and shelter, sometimes traveling miles from the nest. They can be found anywhere on the beach, including far away from signs and fencing.
- Encroaching development has limited nesting habitat, and has also caused an increase in the numbers of foxes, raccoons, skunks, gulls, and crows, which prey on eggs and chicks.
- Piping Plovers and Least Terns are well-adapted to surviving losses in the naturally dynamic system of a coastal beach, but only if the system is intact.
- The best (and only) place for these birds is on the beach. Please enjoy watching these amazing endangered birds from a distance!

How to share the beach with Piping Plovers
- Stay clear of fenced areas marked with “Restricted Area” signs. Observe the birds from a distance.
- If you see a hole that someone has enjoyed digging but abandoned for the day, fill the hole in so no chicks are inadvertently trapped.
- Keep dogs leashed and all pets far away from nesting areas. Roaming dogs and cats are among the top threats to the eggs and chicks of Piping Plovers and Least Terns.
- Fly kites well away from nesting areas. Plovers and terns mistake them for predators and leave their nests to ward off the “intruders.”
- Take your trash and food scraps with you when you leave the beach for the day. Garbage attracts gulls, foxes, raccoons, and skunks, which prey on plover and tern eggs and chicks.
- Notify Maine Audubon of any disturbances to nesting areas.
The Piping Plover and Least Tern Recovery Project is a cooperative effort, with Maine Audubon working in partnership with the Maine Department of Inland Fisheries and Wildlife, the U.S. Fish and Wildlife Service, the Maine Bureau of Parks and Lands, and local municipalities to protect and conserve these rare shorebirds.
