When I heard this fella "booming" in the reeds I put on the audio to see if it would approach. After a few seconds it took flight and offered a couple of quick opportunities before going back down.
Canon 7D + 500mm f/4 II, manual exposure, evaluative metering, 1/2500s., f/5.6, ISO 800, natural light, handheld, added canvas left and below.
