Biology of the Rufous Hornero, from mechanisms to behavioral ecology: a potential Neotropical model species?

Abstract

Model organisms help us understand biological processes and provide insights applicable to other organisms. Birds are commonly used as model organisms. However, since most information comes from songbirds in the Northern Hemisphere, this limits our understanding of broader biological processes. Here we review existing knowledge on the biology of the Rufous Hornero (Furnarius rufus), a non-songbird found in southern South America. We highlight recent advances in research on its nesting, breeding behavior, and vocal communication, and propose promising new research questions. Finally, we discuss the potential of the hornero as a Neotropical model bird species.
