I should have added a note about behavior--especially the tail  
wagging of the two waterthrushes.

When teaching beginning birding, I find that people can relate to the  

Louisiana Waterthrushes move their tails slowly to medium speed, from  
side to side--like a Cajun waltz.

Northern Waterthrushes move their tails more rapidly, more up and  
down--like a Yankee Clipper at sea.
