Harold F. Mayfield was an influential American business executive and amateur ornithologist, known primarily for his significant contributions to the study of Kirtland's warbler. He developed a standardized method of measuring nesting success, now recognized as the Mayfield Method. This innovative technique utilizes probability calculations and accounts for nests that were not located by the observer, a departure from previous methods that relied on naïve calculations. His work has greatly advanced ornithological research and conservation efforts for the breeding habitats of this species.
