I did see a pair of pigeons today, and they did have a rolling gait and matching feathers. One stayed near the little bit of food, and the other strolled off. It looked as though it were meandering, but if you watched for a few minutes, you could see that its zig-zag path covered every bit of sidewalk, that what looked vague and lacking direction actually was an efficient search for more food.

The poem I wrote about this didn't work. Got too caught up in nautical similes and missed the boat (or the point)!
