Male bass in post spawn are more likely to get out and roam around on flats. You'll see them just cruising along in shallow water looking skinny and beat up. Those fish can be caught a lot of times on finesse gear or crankbaits/buzzbaits/etc in dingier water.

Females are what you'll see doing 'log mode', just laying on the bottom or by a piece of wood. They only do it for a few days then they're off to feeding and being more normal.
