We read the reactions to our "Kirrland's Warbl r" article with great interest, and we thank professors Gibson, Howard, McDonald, Wellman, and Rea for their thoughtful responses to it. We will continue employing the Kirtland's warbler analogy in this rejoinder and organize our comments under four sub-headings: I) Birds of a Feather? 2) Feathering our own Nests? 3) Species Invasion and Succession? and 4) Bluebird of Happiness? Our intent is not so much to insist that the respondents are wrong about this matter, burro encourage the reader to ponder the implications if it turns out they are.
