Differences in wing (A) and tail (B) lengths corrected by body size (tarsus length) in breeding females. YI is young immigrant, YR is young resident, AI is adult immigrant and AR is adult resident. P-values correspond to post-hoc comparisons between groups from the interaction dispersal status x age in the LMMs. Values to the left and to the right correspond to differences in young and adults, respectively. “ns” means not significant differences (both P > 0.40). LMMs: wing length in young, estimate ± s.e. = 2.257 ± 0.97, t = 2.33; tail length in young, estimate ± s.e. = 2.026 ± 0.88, t = 2.29. Bars and whiskers represent mean and s.e. values, respectively.

Dispersal decisions are affected by the internal state of the individual and the external environment. Immigrants entering a new population are phenotypically different from residents due to selection that mitigate costs of dispersal and facilitate settlement. Sexual and status signaling traits may influence individual’s ability to settle in a popu...
