River otter activity occurs throughout the course of the Quinnipiac. The author has found that this stretch of the river has traditionally been good at revealing traces of their presence. River otter leave droppings that contain fish bones and scales. Keep an eye out for the droppings or “scats” on horizontal logs on the banks of the river. In the winter, also look for slides and tracks in the snow. The scats are usually concentrated in one area rather than randomly. Otters are fairly secretive.
