Great Blue Heron: York County, Maine, USA, October 2023 — Whoo! That’s cold! The Great Blue Heron in the Mousam River rapids gets in deeper than expected and seems to find the water cold. This is a bird shiver if I ever saw one…and…got to keep those wings dry! OM Systems OM-1 with ED 100-400mm zoom at 372mm equivalent. Program mode with my custom birds and wildlife modifications. Processed in Pixelmator Pro. ISO 5000 @ f6.3 @ 1/640th. I had not realized until posting these photos how much I used the zoom to frame different shots. One of the reasons I don’t use fixed focal length lenses more. 🙂
