Field Station Bulletins
The Ovenbird was selected for intensive study at the UWM Field Station for a variety of reasons. First, it is closely adapted in all respects-morphological, physiological, behavioral- to the upland forest environment, reaching maximum numbers in climax forests, such as the maple-beech forest which is under special investigation at the station. Second, because of its song it can be accurately censused and annual variations in numbers can be detected. Third, unlike most of the hard-wood forest birds, which spend most of their time in the tree canopy, the Ovenbird both nests and feeds on the ground, thus making it more …

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.
