Figure 3. Distribution of feather CORT (CORTf) concentrations measured in urban (n = 109, black bars) and rural (n = 74, grey bars) burrowing owls.

Figure 3

Overlapped, we show the relationship between CORTf and the estimated immediate survival of urban owls (black line, 95% CI depicted as dashed lines). There was not a significant relationship for rural individuals (see Results).
