Growing up in a crowd: social environment shapes the offspring's early exploratory phenotype in a colonial breeding species
In colonial breeding species, the number of adverse social interactions during early life typically varies with breeding density. Phenotypic plasticity can help deal with this social context, by allowing offspring to adjust their behaviour. Furthermore, offspring may not be unprepared since mothers...

In colonial breeding species, the number of adverse social interactions during early life typically varies with breeding density.
