Little egrets (コサギ) are very active at Yasugawa (野洲川) in early August.
When conditions are just right, many little egrets and a few great egrets (ダイサギ) and grey herons (アオサギ) feed on small aquatic creatures at the weir between Moriyama City on the left bank and Yasu City on the right. I recorded some of the action with video and still photos just after sunrise on August 6, 2018, and again in late afternoon on August 8, 2018.

On August 6, 2018, some little egrets and a few great egrets were catching fish in shallow water above the weir in Moriyama City. Others were standing on the weir and feeding on small aquatic creatures.
Often one bird would chase away an interloper. They did not chase other species of birds, but when confronted by an aggressive crow the egrets did not back down.

On August 8, 2018, I went to the river late in the afternoon. The sun was behind my back, and there was a strong wind from the northwest (downstream).
As usual, some little egrets bullied others over territory
A few little egrets crowded up close to much larger great egrets (ダイサギ). Sometimes the larger birds snapped at the little ones when they got too close, but real conflict erupted only between birds of the same species. Once a great egret stopped feeding and marched off to confront another great egret.
Sometimes other birds appeared at or below the weir.
Some of the little egrets were feeding very actively.
As we can see in the video above, sometimes they would slip and fall before taking flight. It seemed that they had temporarily forgotten that they could fly. Of course, little egrets fly very well!
All photos and video clips were shot handheld with an Olympus OM-D E-M1 Mark II camera and M. Zuiko Digital 40-150mm f/2.8 PRO lens. Some closeup scenes were shot with the camera’s 2X digital teleconverter.
All postprocessing was done on a Fedora GNU/Linux workstation. I edited the video clips and added titles with with Kdenlive, but I did not modify the colors or add any enhancements. Photos were organized and edited with digiKam.
