Here’s an odd observation from a young child who has since infancy displayed an odd talent at visual recognition of things that are barely noticeable, possible synaesthesia and a marked tendency toward pareidolia.
While travelling in a booster seat at the back of a car the child was looking at the road directory. The child declared that she knew why there are swans on the Swan River. The child was looking at a map of the Perth Water section of the Swan River. She insisted that when the swans were flying around, they look down and spot a section of river that looks like the shape of a swan, which gives them a nice feeling of familiarity, so they fly down and land there. You can see this if you look at the map, but I never would have picked the swan shape unless I had it pointed out to me. Kids!
