Ruddy turnstones show a striking color pattern in flight: a white stripe down the back, black tail stripe, white rump, and white stripe down the wings. All ruddy turnstones have orange legs, which are brighter during the breeding season.
Breeding males have black-and-white markings on their head and throat with a rufous and black calico cat-like pattern on their back. Breeding females are paler than males. Nonbreeding adults have a brown feather pattern. Juveniles look similar to nonbreeding birds but have rusty edges on their feathers.
Turnstones have a sturdy, slightly upturned bill that helps them flip over stones, shells and seaweed while looking for food. Their short, curved toenails and slightly spiny feet allow them to move around safely on slippery rock surfaces. They rely on their short legs and a low center of gravity to stay balanced.
Ruddy turnstones forage for food by using their upturned bills to flip over rocks, shells, pebbles, etc. During the breeding season, they feed primarily on larval flies and midges, but will also eat spiders, beetles, bees, wasps and other insects. They are also known to pick at dead fish and mammals that wash up on shore before insects emerge in the summer.
Their diet is more varied during nonbreeding season, and includes small crustaceans, mollusks and bird eggs.
They are monogamous and often return to the same breeding site to mate with the same individual year after year. Males and females both perform noisy ground and aerial displays to strengthen their bond. The female chooses the nesting site within the male's territory and builds a shallow nest, or scrape, in the ground with her body. She may also use small bits of vegetation to line the bottom of the scrape. The scrapes are often made in wet areas near vegetation and out of the wind, but they can also be found on bare gravel or in sand barrens.
Females will lay two to five eggs, which are olive green to cream in color with brown speckles. The incubation period is 21-24 days and both parents take turns sitting on the nest.
Newly hatched chicks are mobile and able to feed themselves. Both parents take care of the young, but the female will depart before the chicks can fly. The male will stay until the chicks fledge at 19 to 21 days old.
Ruddy turnstones are a relatively common shorebird, but the remoteness of their breeding grounds makes it difficult to estimate their population trends. One study estimated a 77% decline in the number of turnstones around Delaware Bay from 1988 to 2007.
Major threats include habitat loss, plastic pollution, lack of availability of food and climate change.
- Be a smart consumer. Choose products made with sustainable ingredients, such as Smithsonian certified Bird Friendly coffees, which support farmers striving to limit their impact on wildlife and habitat.
- Practice ecotourism by being an advocate for the environment when you’re on vacation. During your travels, support, visit or volunteer with organizations that protect wildlife. Shop smart too! Avoid buying products made from animals, which could support poaching and the illegal wildlife trade.
- Be a responsible cat owner, and keep cats indoors or under restraint when outside. Never release animals that have been kept as pets into the wild.
- Organize or attend a stream, river, lake or other waterway cleanup in your area to preserve aquatic habitats for local species.
- Avoid single-use plastics, such as plastic bottles, bags and utensils. Choosing reusable options instead can help reduce plastic pollution.
- Never release balloons. Animals often mistake them for food or become entangled in their strings. Looking for an alternative? Try blowing bubbles instead!
