Abstract: Objectives To determine if mountain chickadees experience a diurnal pattern of change in mass during winter and to monitor survivorship of chickadees. Findings and Status This project began in mid-December, 1997. During 1997 and 1998, 38 mountain chickadees have been captured; 5 mountain chickadees originally banded in January - April, 1998 were recaptured during November - December, 1998. Mass measurements of recaptured chickadees indicate a noticeable weight difference between morning and late afternoon weights. Other birds captured and banded: 109 pine grosbeaks, 9 Cassin's finches, 5 red-breasted nuthatches, 15 dark-eyed juncos, and 1 American tree sparrow.
