Cool pictures. Years ago while in a deer stand I witnessed two otters work down Rabon creek with a grey heron in tow. The heron would stand at pool side as the otters worked cut banks and pick off fish that were driven out. I watched that heron catch, walk to sand bars to reorient head first and eat 3 10-12" catfish. The otters would occasionally disappear into muddied water and reappear 20 yards up or downstream. The heron would then immediately run and fly to catch back up. I've run up on them turkey hunting more often than anything and they seem to be very curious creatures, far from spooky.
