DOCTORATE DISSERTATION: The breeding biology and feeding patterns of the Oregon junco (Junco hyemalis thurberi) were studied in the Sagehen Creek basin in the central Sierra Nevadas of California, from Oct 1968 through July 1972. Breeding populations were followed in the yellow pine forest on the basin ridges and in the meadow areas along the basin bottom...... This project was designed to study the breeding ecology of the Oregon junco, and to compare populations in the forest and meadow habitats. In addition to breeding history, feeding data were recorded in these two habitats in an effort to determine how juncos utilized the habitats for obtaining food and the ease with which they obtained food.
