His vision and hearing do seem unusually perceptive.

Examples:

He can hear the slight hum of some electronics from another room when the power is on but they are not actually playing.

He can sometimes hear his clothing move while he walks.

He can spot small camouflaged wildlife like crazy. His teacher has noticed this as did a naturalist at a local museum.

He can beat anyone I know on those "spot the difference" photos.

I am SO hoping all of this gets figured out over the next few months.
