When I found this mountain stream, I was surprised about moss. So much moss is everywhere and some of them are so beautiful. First of all, I must watching wren's move few days and found his favorite route. Then on these route, I chose best point carefully. At this point, my work is almost finished. Then I just wait for wren to come that point … Although it took 5 more days to took this image. But for me, it's worth to wait. Because this is almost perfect image I imagined. Moreover this became award winning picture of Japan Bird Festival 2013.
