Tree Swallows: York County, Maine, USA, May 2024 — So who owns this Bluebird box anyway? These two Tree Swallows are ready to fight over it…but in the end the Bluebirds are likely to claim it…they did last year. 🙂 Interestingly there were a group of at least a dozen Tree Swallows around the tidal stream when I went out…and none at all when I came back. They do nest somewhere in area. I will see the young on the rail of the bridge before long. OM System OM-1MKii with M.Zuiko 100-400IS zoom at 800mm equivalent. Program mode with my custom birds in flight and action modifications. Processed in Photomator and assembled in FrameMagic.
