Resist the urge to throw rocks to see a flock fly. Give nests a wide berth. You could frighten the parents away and leave eggs or young animals exposed to predators. Avert your gaze, as animals may interpret a direct stare as a threat. 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.
