There is little information on Rock Sandpiper population trends and numbers. A 2012 study noted that no new population estimates had been made since 2006; at that time the total continental breeding population was estimated around 145,000 birds. At least one subspecies in the Bering Sea may be in decline. Rock Sandpiper is not on the 2014 State of the Birds Watch List. Back to top
