No, this isn't about an owl named Spot. It's a challenge, a game, an instruction of sorts.
Today I went to Terra Nova to lead a bird walk. I parked my bike at my brother-in-law's house, and walked through the rural park to get to the meeting place. On the way I passed (in the distance) a spruce tree that was getting noisy attention from crows. Hmmm, I thought.
The bird walk wound through the park, and as it approached the spruce tree (in the distance), the crows were still busy. Hmmm, I thought.
I left the group behind, and approached the tree. Oh, there it was, a dark blob halfway up. Silhouetted crows were helpfully pointing their bills.
It took a while, but all the birders eventually saw the owl (Bubo virginianus, Great Horned Owl). The bird, master of cryptic colouration, wasn't easy to see through branches, and in the shadows.
