Many wildlife-watching lists emphasize birds, for good reason. Birds are often easier to spot, as they roost in trees or brush and take to the air. And they can often be seen at any time of day, unlike many walking animals that only emerge from cover only at dawn or dusk, or during the night. You may not always see the other wildlife, but you will almost always see birds. But don't forget to look for signs of other animals, even if you can't see them.
Signs can include tracks, mounds, beaver dams.
A field guide can help you learn what to look for, and where. Visitation may be limited to certain seasons to protect wildlife during critical periods, such as fawning or nesting periods. Travel through a special area may be limited to foot traffic only, where vehicle use could impact sensitive resources. Respect the rights of private landowners at or near viewing areas.
