These birds are world travelers. They are common along the shore, worldwide. Their range for breeding, and migration looks like they live all over.
This one was on a sandy barrier island, not their favorite place to be but a safe place to rest while traveling.
They are called ‘Turnstones’ because that’s exactly how they feed. Walk along rocky coast lines flipping over small rocks for prey.
Preferred breeding locations are in northern Canada, way north. They will also fly down to South America. West coast birds, travel between Alaska and Hawaii. That’s a huge flight and range.
Turnstones are members of the Piper family and from the last two images they will hunt like Sandpipers if no rocks available.
I have never seen a single bird like this. Usually they will work in small flocks.
