A community park a mile from my house I regularly walk to. Red-winged blackbird perched in cattails at sundown. This was mostly chance. I walk in this park most days and occasionally carry my camera to shoot songbirds. I happened to be in the right place at the right time. As an aside, a D850 with a 600mm zoom gets one looked at (or interrogated by a wannabe Defender of the Public Good, in one instance) in a community park.
