I was out playing alone on a cold, foggy morning when suddenly I heard a startling chorus of whouks coming toward me through the air. I peered intently at the thick fog, hoping for at least a glimpse of the geese. All of a sudden, bursting through a gap in the fog, came a large flock of pearl-white snow geese. For five or six wonderful seconds their sleek and graceful forms were visible, then they merged once again in the fog. Their fading calls seemed to say follow us, follow us.
Children are especially aware of their kinship with animals.
Any child will tell you that the most important part of a nature outing is seeing wild animals. There is a bird call that you can easily do with no more equipment than your own mouth. The call consists of a series of rhythmically-repeated psssh sounds. Different rhythms work with different birds. Each of these series should last about three seconds.
