Sand Lake is THE place to go for waterfowl in the state. Not only can as many as two million Snow Geese be present on a given day in spring, Sand Lake was one of the first places to re-establish breeding Bald Eagles. Sand Lake is also great for many other migrant species. The rest areas are great for warblers and vireos, the lakes are great for gulls, terns, and grebes, the ponds at the southern end are great for shorebirds, and the surrounding fields are great for sparrows and things. Sand Lake occasionally has rarities show up like a breeding Common Moorhen, White Ibis, Whimbrel, Brant, and Piping Plover and the staff at headquarters is very up to date on what's in the refuge and very helpful.
