I saw this Curlew Sandpiper at Swan Harbor Farm in Harford County, MD on Oct 24th, 2020. These are very rare in this area. These birds are normally found in Asia, Europe, and Africa.
The Curlew Sandpiper is in front of this group. Note the white rump and white line on the upper wings.
The Curlew Sandpiper is at the bottom in the two photos above.
