INTRODUCTION

Through an oversight by the Editor, the year of publication of Murray's letter (Auk 125:232–233) is given in the title of Chardine (Auk 125:233–234) as "2007"; it should be "2008" (in the title, and also in the citation of Murray's letter on page 234). The correct title of Chardine's letter is "Mass or weight: What is measured and what should be reported—Response to Murray (2008)."
