American Bittern

I've only seen one American Bittern in the past and that was at RNWR along the canal after marker 12. So each time I take the auto tour, I'm on the watch for them in that area. Their coloring blends in well with the dried grasses and weeds so they can be easy to miss.
As I rounded the corner entering this area on my last trip, I saw one flying off, so I thought my chance of seeing one that day just flew away, but I actually saw two more along the Canal.
Note the size of their feet. I haven't seen feet proportionally that large since seeing the Common Moorhens in Montreal.
