We are deep in the Troll Woods when Aki alerts, stiffening as she points her noise in the direction of recent motion. Then she barks. I stop berry picking and look where she is looking. Expecting a bear, I spot a gang of thrush, maybe ten of them, dive bombing blueberry bushes. The bushes bounce up and down as each bird flies away. They bounce again each time another thrush flies into them. 

            After thinning out the fruit on their targeted bush, thee birds fly over our heads and attack another one. I had suspected bears or people had plucked most of the bushes clean. But the bear poop we passed to get here was grass green, not berry blue. It must be the work of the tenacious thrush.
