You will certainly see fox squirrels and red squirrels scurrying through the woods as you parallel the north edge of the lake. From the end of September to mid-October, the green foliage changes to a mosaic of reds, yellows, and oranges, and with those changes come the annual migration of wood ducks, Canada geese, bobolinks, and bluebirds, as well as many other birds. As fall progresses, you may see sandhill cranes winging overhead, migrating to their southern wintering grounds. And as the days gradually get longer and warmer, late winter and early spring brings an escalation of activity to the Lake La Su An Wildlife Area. As spring moves along, ring-necked pheasants can be heard crowing and wild turkeys can be heard gobbling, interrupting the morning songs of Eastern meadowlarks, field sparrows, cardinals, and numerous, colorful warblers in the uplands.
Spring is also a good time to take a walk on the service roads around some of the smaller lakes.
And as you hike near these water areas keep an eye on the downed trees protruding from the water, for there you'll see midland painted turtles, map turtles, and Blanding's turtles sunning themselves. If you're lucky, you may even spy the endangered copperbelly water snake. An Wildlife Area is the only place in Ohio where this snake exists. Spring is also an exceptional time to visit the area for birding in the fields. If you come upon one of the many small marshes, you can view tree swallows, wood ducks, mallards, blue-winged teal, great blue herons, green herons, killdeer, and greater yellowlegs.
