The appreciation of birds, indeed the appreciation of all the phenomena of spring, cannot be dissociated from the accumulations of memory. The appearance of a familiar bird immediately awakens a train of forgotten associations, and this makes each spring transcend its predecessor. The interest accumulates and is compounded. The first yellow-throated warbler next year will be the more meaningful to me as it brings back that moment in the woods opposite Dyke. For one remembers clearly enough the fact of such a moment, but only an evocative sight or sound or smell can bring back the full emotion. The person who sees the bird for the first time cannot know what moves me.
