No photos unfortunately, but the dippers were doing battle for territory late yesterday. I watched, fascinated as they knocked each other off rocks and into the river, then had to swim to another rock. Repeatedly doing this, flying upriver and coming back to do the same. One finally flying off, swerving at a duck in its aggressive state.
This is the point where I wished I was carrying a better camera than my phone!
Updated river fly diaries this morning - the season begins! Enjoy!
