A territorial male can shift the location of its territory from year to year in order to increase its quality. The male can
base its decision on environmental cues or else on its breeding experiences (when territory shift is caused by breeding failure
in previous seasons). We tested these possible mechanisms of territory choice in the sedge warbler (Acrocephalus schoenobaenus), a territorial migrating passerine that occupies wetlands. This species bases its territory choices on an environmental
cue: tall wetland vegetation cover. We found that the magnitude of territory quality improvement between seasons (measured
as the area of tall wetland vegetation) increased throughout the early stages of a male's breeding career as a result of territory
shifts dependent on the earliness of arrival. The distance the territory was shifted between seasons depended negatively on
the previous year's territory quality and, less clearly, on the previous year's mating success. On the other hand, previous
mating or nesting success had no influence on territory quality improvement between seasons as measured in terms of vegetation.
The results imply that tall wetland vegetation is a long-term, effective environmental cue and that a preference for territories
in which this type of landcover prevails has evolved into a rigid behavioral mechanism, supplemented by short-term individual
experiences of breeding failure. 相似文献
