Foul Owls Use Feces To Show They Are In Fine Feather

Some years ago, within the Department of Conservation Biology of the Estación Biológica de Doñana (EBD-Consejo Superior de Investigaciones Científicas; Seville, Spain), a recently established group (colloquially named the Night Ecology Group) started to explore the possibility of visual communication in crepuscular and nocturnal birds.

New research on this topic challenged the common belief that social communication in this group of species is limited to vocal signaling. By using the largest European owl (the eagle owl) as their biological model, members of this EBD group (Drs Vincenzo Penteriani and María del Mar Delgado) discovered that these crepuscular and nocturnal species use visual signaling in intraspecific communication, both in territorial and in parent-offspring contexts.
