This paper has been suggested by Yamato Tsuji :o)

he seems to be atracted by compromises in the reproductive success. In this paper:

Noris, DR, Marra PP, Montgomerie R, Kyser TK, and Ratcliffe LM. 2004. Reproductive effort, molting latitude, and feather color in a migratory songbird. Science 306: 2249-2250,

the authors show how migrant American redstars face important trade-offs regarding the timing of three important vital processes: reproduction, molting, and migration. How to improve life-time reproductive success under different circunstances? Please read the paper :o)

Thanks Tsuji!
