Pine Warbler: Kennebunk, Maine, USA, September 2026 — I watched this Pine Warbler foraging in a squat red pine along the trail, probing deep into the needle clusters, until it came out with this small caterpillar. It turned, almost as though to show me its prize. After a lot of back and forth with ChatGPT and uploading several photos from the sequence and an enlargement of the caterpillar, this might be a Jack-pine Tube Moth caterpillar. Might. There is a lot to like about this photo though. The lighting. The pose. The background. This is a pine warbler at work, doing what pine warblers do. In September. In southern Maine. USA. Sony a7CR with the new Sony FE 100-400 f5.6 – f8 lens at 400mm. Cropped to 13mp so about 900mm effective field of view. My custom bird and wildlife mode based on Program. Processed in Photomator.
