Hematological health state indices predict local survival in a small passerine bird, the great tit (Parus major).

In birds, it has been shown that reproductive effort may impair parental condition, while the relation of different condition indices to subsequent survival is still poorly understood. In this study, we measured body mass and various hematological condition indices in breeding great tits in relation to local survival. Number and quality of nestlings and the… CONTINUE READING
