It flew in from the opposite bank on a warm winter afternoon. It circled the sky several times before returning.
It looked smaller than a carrion crow, so I thought it might be a goshawk. After taking a photo, I identified it as a goshawk based on its distinguishing features.
It appears on sunny days when the temperature rises. When a goshawk appears, the small birds in the reeds suddenly become quiet.
