A naturalist's series of observational essays explores the varied ways birds and mammals communicate, from vocal cries and scent signals to visual postures and coordinated group movements. Anecdotal field accounts and reflective passages consider apparent telepathic responses, the social impulse behind swarming, the eloquence of silence, and techniques for getting acquainted or keeping still while observing. Practical chapters examine trail signs, beaver engineering, duck and deer behavior, and the role of memory in animal life. The tone combines close, descriptive scene-setting with interpretive reflections and illustrative sketches.
