As the shorebird migration tapers off, it is still possible to observe smaller numbers of lingering migrants on their way south. The Least Sandpiper is found during fall migration along the coast, especially around tidal mudflats and coastal shorelines. This little sandpiper, with its brownish gray plumage, at times becomes hard to find as it blends in so well with nearby surroundings. The Least Sandpiper has brownish gray upperparts, white underparts, and distinctive yellowish green legs.
