Little is known about how bird behavior and territoriality changes throughout the year, in part because it is difficult to observe migratory birds in both their summer and winter habitat. Non-migratory birds are particularly interesting, because many maintain year-round territories. These territories must serve different functions throughout the year but do they require the same behaviors to maintain them? I propose to investigate territorial behavior, song, and territory size in Anna?s hummingbird, a non-migratory bird that is common in southern California and maintains year-round territories. I will observe individual males on their territories in a natural and an urban habitat, collecting behavioral data, representative songs and measures of territory size. These observations will occur once a month throughout the year, to look for seasonal changes in territorial behavior. This work will provide insight into the relationship between the function of territories and the behaviors used to maintain them.
