Data from: An experimental test of the relationship between yolk testosterone and the social environment in a colonial passerine
Maternal hormones can be transferred to offspring during prenatal development in response to the maternal social environment, and may adaptively alter offspring phenotype. For example, numerous avian studies show that aggressive competition with conspecifics tends to result in females allocating mor...
