Chickens aren't usually bimbling, but a mother
duck and a line of ducklings crossing a road and heading into fields probably are. A duckling that breaks away from the group, explores busily and then returns has just had a bimble.
In the Sahara miles from anywhere, a
guy walked out of the midday haze carrying nothing but a piece of
wood, passed by 50 yards away without looking at
us, and headed into the heat. Now HE was bimbling.
