Rainfall, but not temperature, negatively affects the growth of Blue Tit Cyanistes caeruleus nestlings

Capsule: Growth trajectories of Blue Tit Cyanistes caeruleus nestlings differed between sexes and were negatively affected by rain but not by temperature during the linear growth phase (LGP).Aims: To model the growth trajectories of Blue Tit nestlings and to identify the main ecological factors affecting them.Methods: Sixty-five nestling Blue Tits from a population in northern Italy were weighed at regular intervals and sexed using molecular...
