A Mouthful of Bullfrog

An American bittern prepares holds a large bullfrog in its mouth

Normally I’m pretty good at spotting bitterns at Ridgefield but I saw them on only three out of ten visits to the refuge over the Christmas break. I worried I was losing my touch until I found this bittern on Christmas Eve slowly working the channel beside Rest Lake. I suspect the real reason I haven’t seen as many this year is that the grasses in this area, normally my best spot for seeing them, have been cut lower in places, eliminating cover for both the bitterns and the animals they are hoping to catch.

The bittern snagged a large bullfrog from the water as you can see in the top picture. In the picture below the bittern has swallowed most of the frog with only the rear feet sticking out of its mouth. The bittern has protected its eyes from the frog’s claws with a nictitating membrane, a common tactic in the chaos of swallowing something that doesn’t want to be swallowed.
