Representation of time spent as either territorial or nonterritorial under fluctuating and stable conditions, respectively. Shown are the median (dark horizontal bar) and interquartile ranges (thick vertical bars), as well as minimum and maximum. The median duration of territoriality is 3 weeks in the fluctuating condition (n = 52) and 9.5 weeks in the stable condition (n = 14). In contrast, the median time spent as nonterritorial is only 4 weeks in the fluctuating condition (n = 55), compared with 7 weeks under stable conditions (n = 15).
