Acoustic signals in anurans are classic models for understanding how endocrine mechanisms regulate courtship behavior. However, our understanding of how steroids influence male calling performance remains limited because most studies examine single hormones or isolated call traits. Here we quantified three plasma steroids—testosterone (T), estradiol (E 2 ), and corticosterone (CORT)—from male Cope’s gray treefrogs ( Hyla chrys...
