Swamp Spreadwing (?) doing calisthenics. Day Brook Pond, Kennebunk Plains Nature Conservancy, York County, Maine, USA — the spreadwings seem very few in number this year, and very late. ?? I think this is a Swamp Spreadwing doing interesting things with its abdomen. OM Systems OM-1 with the ED 100-400mm zoom at 800mm equivalent. Program mode with my custom birds and wildlife modifications.
