Table 3.

Daily and cumulative nest survival probability. Model-averaged daily survival rates (DSR) and mean duration (length) in days of each period of the nesting cycle for nests of communally breeding greater anis, with respect to group size (two or three females) and stability (stable, all females nested together the previous year; unstable, at least one female joined or left the group since the previous year). Significant differences between stable and unstable groups are given in italics; asterisks indicate statistical significance at p = 0.05 (*) or p = 0.01 (**).
