ABSTRACT
Supplemental feeding of a wintering population of 132 white-throated sparrows was suspended in midwinter to determine characteristics associated with the tendency to remain within previously established home ranges after a drop in food levels.		Site-faithful birds tended to be dominant, to have high levels of subcutaneous fat and to reside in certain regions of the study area. The high site-fidelity of dominant sparrows reaffirms the importance of dominance in structuring populations.
