Bittern

A bittern (Botaurus lentiginosus) hides motionless in the vegetation. In the Celery Bog Park wetland just south of Cumberland Ave.  I noticed this bird while passing by but wasn't sure that it was a bird and not another piece of vegetation until I stopped to get a good look at it. 

 It didn't move a bit for a few seconds, here is a closer picture of it.

Then it moved into this position and froze motionless again. Pictures taken Oct. 28, 2012.
