Stream Cruiser, Cold Brook Pond, Kennebunk Plains Wildlife Management Area, Kennebunk, Maine, USA — I am thinking the north side of the Kennebunk Plains is still under State management, as the signs have not been replaced, but the big yellow gates are up there too, limiting access to Cold Brook Pond at the back of the plains as it slopes off to the Mousam River. I did make out there on my last odes trip to the plains, and found many Stream Cruisers patrolling the path as though were a stream. Males this time, and perhaps a few females that did not perch for me. Sony Rx10iv at 600mm equivalent. Program mode with my custom birds and wildlife modifications. Processed in Polarr and Apple Photos. I noticed something I had never seen before. The club on the end of the abdomen was “breathing”, visibly swelling and contracting in a regular rhythm. ??
