Since Dr. Rudolph M. Anderson wrote "The Birds of Iowa" in the year 1907 there have been many changes in conditions over the state. Population has greatly increased, rural districts have become much more thickly settled, sloughs have been drained, woods have been felled, and spots of untouched wild prairie are now a curiosity. These have greatly changed our bird life. So have other influences. Surprising it is that Dr. Anderson's splendid book, which is still the authoritative publication for the state, has so well stood the test of time, yet twenty-three years since its issuance cannot do other than necessitate revisions. Someday soon an ornithologist will issue a new book to be entitled, "The Birds of Iowa" portraying the present bird life of the state.
