While I was at the river watching my heron, I could hear a cacophony of birds in a tree across the river. When I looked closer I could see a large number of birds perched in the tree.
Then all of a sudden, they all took off flying and just as quickly returned to the tree. They did this several times. I’m not sure what birds they were but they could have been starlings. While the photos aren’t very interesting, they were fun to observe.
