Identifying small shorebirds can be difficult.That is why a few years back I traveled to South Dakota for a few days to take a workshop on shorebird identification. The workshop was informative and we got great looks at a number of different species of shorebirds. This one is a least sandpiper. One way that you can identify a least sandpiper is by its yellow legs. Most of the similar looking sandpipers, at least in my corner of the world, have black legs. You do have to be careful though because sometimes the legs get covered up with much. I guess that is a hazard of walking around in the mud. I am still not an exert in shorebirds, in fact I may need to go back for a refresher course soon, but I did learn a lot in the workshop.
