The winter trapping program was begun in the winter of 1965-66 and was expanded and conducted more systematically in 1966-67 and 1967-68. The primary objective has been to determine accurately the daily and seasonal changes in body weight and depot fat in the Chickadee and Junco. Secondarily, we (my students and I) have been interested in the winter population densities of these birds, their organization into social groups and flocks, their movements and range of activity in the local area.
