The Minds and Manners of Wild Animals: A Book of Personal Observations

IV THE MOST INTELLIGENT ANIMALS To the professional animal-man, year in and year out comes the eternal question, "Which are the most intelligent animals?" The question is entirely legitimate. What animals are the best exponents of animal intelligence? It seems to me that the numerous factors involved, and the comparisons that must be made, can best be expressed in figures. Opinions that are based upon only one or two sets of facts are not worth much. There are about ten factors to be taken into account and appraised separately. In order to express many opinions in a small amount of space, we submit a table of estimates and summaries, covering a few mammalian species that are representative of many. But, try as they will, it is not likely that any two animal men will set down the same estimates. It all depends upon the wealth or the poverty of first-hand, eye-witness evidence. When we enter the field of evidence that must stand in quotation marks, we cease to know where we will come out. We desire to state that nearly all of the figures in the attached table of estimates are based upon the author's own observations, made during a period of more than forty years of ups and downs with wild animals. ESTIMATES OF THE COMPARATIVE INTELLIGENCE AND ABILITY OF CERTAIN CONSPICUOUS WILD ANIMALS, BASED UPON KNOWN PERFORMANCES, OR THE ABSENCE OF THEM. [Footnote: To the author, correspondence regarding the reasons for these estimates is impossible.] [beginning of chart]
