To quickly assess the difficulty of the text, read a short excerpt:
So, if we are to recognize this bird as distinct from the European, it is apparently the former and not the latter which be- longs on the American list. The European bird, Gavia arctica arctica (Linnaeus) seems to have no standing as an American bird. I have been unable to find an American specimen which I could identify as arctica; all the speci- mens which I have been able to locate, taken in eastern North America, are either typical pacifica or are nearer that than anything else. Numerous re...cords are based on erroneous identifications of immature common loons, Gavia immer. For further information re- garding all the American records that we could trace, I would refer the reader to a recent paper on the subject by my assistant, Mr. F. Seymour Hersey (1917). I have therefore no reason for including the life history of the European bird in this work. So little is known about the distribu- tion and habits of the Asiatic bird that I shall not attempt to write a fragmentary story, which probably would not differ materially from what I have written about the Pacific loon.
