A cacophony is a “harsh discordant mixture of sounds” . The thousand of blackbirds coming through made a loud and harsh landing in the trees all along the dam and some even at the edges of the lake.The blackbirds congregate for food and protection and seem to find strength in numbers. The last several late afternoons the swarm through allow us to enjoy the comotion. The photo is a phone pic and doesnt show what really happens.
