You'll need an eagle eye to learn anything from these undistinctive black-and-white illustrations but normal acuity will uncover physical characteristics, habitats, prey procedures, etc. in the text. Individual parts--eye, bill, talons, wings and tails--get individual attention, and there are separate sections for (1) golden and (2) other land eagles, (3) baldheaded and (4) other sea eagles as well as (5) more regal eagles. Throughout the author includes poetic, historic and legendary material (debunking where necessary), isolates figurative usage (e.g. Eagle scout) to indicate the bird's notoriety, even adds a bit on falconry. The wide wing spread could be organized for greater efficiency but the straightforward language (""the egg of a golden eagle weighs about 140 grams, or about the same as a Little League baseball"") is right in hand. The only factual alternative is Johnston's fuller but no better organized The Eagle in Fact and Fiction.
