However, the park is open for visitors at any time. Pets, picnics, leaving the special trails, gathering of any items and disturbance of anything are not allowed.

The 231 bird species, nesting or migrating, can be observed in the Sanctuary. Herons, Plovers, Sandpipers, Gulls, Woodpeckers, Flycatchers, Swallows, Chickadees, Nuthatches, Wrens, Thrushes, Vireos, Warblers, Sparrows and many others are among them. Always there are always many waterfowls on the Lab pond. One can see American Black Ducks, Mallards, and Canada Geese, which allows one to approach them very closely. A visitor from the Old World is struck with the bright reds, yellows, greens, and blues of the many species.
