The clade, Archosauria, encompasses crocodilians and birds. Both crocodilians and birds exhibit vocalizations to communicate a variety of behaviours including courtship, distress, and aggression. The similarity in vocalization behaviours of modern day Archosauria suggests that vocal communication may be a conserved behavioural trait also exhibited by ancient Archosauria.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
