I want to know the answer to the following question:
What are waders called in North America?
All the background I'm provided with is that "Many species, such as dunlin Calidris alpina and western sandpiper Calidris mauri, undertake long movements from their Arctic breeding grounds to warmer locations in the same hemisphere, but others such as semipalmated sandpiper C. pusilla travel longer distances to the tropics in the Southern Hemisphere.". Is that enough to answer the question?
Answer: no
