Vertical photo of an iron crossbeam over part of a river dam structure against a sunny backdrop of chain-link fencing and rushing river rapids. Two different species of heron stand like odd, clockwork chickens waiting for the bell to chime: In right-facing profile in the lower left of the photo (on the near side of the beam) is the stocky brown, speckled figure of a black-crowned night heron in the juvenile colorway, skulking and red-eyed and looking off downriver; in left-facing profile in the upper right of the photo (on the far side of the beam) is the shaggy, blue-cloaked, long-legged figure of a great blue heron, staring upriver through a yellow eye that gazes across a thick sword of yellow bill. They are matched only in their stillness.
