A Louisiana Waterthrush

I've seen a Louisiana waterthrush in the Garden before, but didn't remember its song.

I heard it yesterday, with the director of the Garden, a great naturalist, who pointed it out to me, and then again today, on a lunchtime walk with a good friend.

It's a wonderful song. 

I imagine it's a male waterthrush, marking his territory. They apparently sing quite a bit upon arriving in their summer breeding grounds, being much quieter after that.

I heard it at exactly the same spot on the fern extension of the Woodland Wildflower Garden trail as yesterday.
