While scanning the marshes at Herrick's Cove in Bellows Falls, I saw a bittern with white feathers!! I realized he was doing a courtship display for the female!!
The pictures were taken through my spotting scope with my Canon PowerShot, so the quality is not good. But I read on the Audubon website that "the bittern has a remarkable, though rarely seen, courtship display" so I decided to share the pictures anyway.
Audubon goes on to say "the male arches his back, exposing whitish plumes, shortens his neck, dips his breast forward, and "booms" at the female."
He followed her through the grasses and eventually I lost sight of them. Later on, they both flew across the marsh, the male looking noticeably larger.
