While working on my pond film, I had a chance encounter with a bunch of Water Snakes that were interacting, sort of. The smaller one kept trying to engage with the medium-sized snake, but he/she would have none of it. After a time, an even larger Water Snake appeared on the scene and made his way to a sunny spot on a hummock in the pond.
I read that Northern Water Snakes are mostly solitary creatures. They are generally social only in the fall and spring.
The Northern Water Snake swallows its prey whole, feeding heavily on amphibians and fish. The above photo is of the closely related Garter Snake swallowing a Bullfrog as I was so engaged with filming the Water Snake, I neglected to take a photo.
