Black turnstone Facts
Black turnstone is wading bird that belongs to the family of sandpipers. It can be found along the western coast of North America. Black turnstone inhabits rocky shorelines, sandy beaches and piers. Oil spills, floods and predators are the greatest threats for the survival of black turnstones in the wild. Despite these factors, global population of black turnstone is large and stable (there are around 95.000 black turnstones in the wild). Black turnstone is not on the list of endangered species.

Black turnstones expose white markings on the wings and tail and produce loud calls to find mating partner. Formed couples last for a lifetime (monogamous birds). Black turnstones use exactly the same location for the nesting each year. They are very aggressive during the nesting season.
Male is responsible for the construction of the nest (shallow depression in the ground lined with grass). Female lays 4 eggs that hatch after 21 to 24 days. Both male and female take part in the incubation of eggs.
Black turnstones are able to walk and feed on their own soon after hatching. Female usually leaves chicks with their father two weeks after hatching. Male continues to take care of his offspring until they learn to fly, at the age of 25 to 34 days.
Black turnstone can survive 4 to 8 years in the wild.
