INTRODUCTION

The review process is essential to the maintenance of high scientific standards in a journal. The efforts of individual reviewers are remarkable, and we take this opportunity to acknowledge publicly those who contributed reviews during the period that Volume 125 was in preparation (reviews completed between 1 July 2007 and 30 June 2008). Individuals who reviewed two or more manuscripts are signified by an asterisk. We also acknowledge the hard work of the Associate Editors, listed on the inside of the front cover of The Auk, whose impartial assessments of the manuscripts and the reviewers' comments provided the basis for the their recommendations to the Editor. Memorials and book reviews were solicited and managed by Alan H. Brush and R. Todd Engstrom, respectively.
