A ruddy turnstone is a small bird with contrasting colors of black and white. The birds, while flying, looks like a white wing bar. The turnstone makes chattering alarm calls during the breeding season.
The young birds are cute with a pale brown head and the upper feathers with fringes appear as scales. They are very colorful birds and have two subspecies. These subspecies are called Arenaria interpres and Arenaria marinella.
They are diurnal in character which means that they are most active during the day. These birds are quite territorial and turn very aggressive during the season of breeding. They draw their names from their special habit. They have a unique habit of flipping stones while looking for food.
These birds have quite a stable population. According to the Environment Canada surveys, the bird population decreased considerably during the '70s and faced several threats during winter and migration.
However, the number has increased and the species is now found widespread due to the safeguarding of their habitats where they successfully breed after migration. Around 235,000 birds are breeding in North America.
