Least bittern
Seen at Rondeau Provincial Park, August 26, 2016, along the marsh edge.
A hard to find/see bird even without the fish it just caught.
Ixobrychus exilis
John James Audubon noted that a young captive Least Bittern was able to walk with ease in a 1.5-inch gap between two books, even though the bird's body normally measured 2.25 inches across—indicating that it could compress its body to an extraordinary degree to squeeze between marsh stems and reeds.
