==Communication==
Owls, such as the [[Horned owl|eagle-owl]], will use visual signaling in [[Animal communication|intraspecific communication]] (communication within the species), both in territorial habits and parent-offspring interactions. Some researchers believe owls can employ various visual signals in other situations involving [[Biological interaction|intraspecific interaction]]. Experimental evidence suggests that [[Pellet (ornithology)|owl feces]] and the remains of prey can act as visual signals. This new type of signaling behavior could potentially indicate the owls' current reproductive state to intruders, including other [[Territory (animal)|territorial]] owls or non-breeding floaters. Feces are an ideal material for marking due to its minimal energetic costs, and can also continue to indicate territorial boundaries even when occupied in activities other than territorial defense. Preliminary evidence also suggests that owls will use feces and the feathers of their prey to signal their breeding status to members within the same species.<ref name="Owls May Use Feces and Prey Feathers to Signal Current Reproduction">{{cite journal |first1=Vincenzo |last1=Penteriani |first2=Maria |last2=del Mar Delgado |title=Owls may use faeces and prey feathers to signal current reproduction |url=https://core.ac.uk/download/pdf/36018785.pdf |journal=PLOS ONE |date=August 2008 |volume=3 |issue=8 |page=e3014 |name-list-style=amp|doi=10.1371/journal.pone.0003014 |pmid=18714382 |pmc=2507733 |bibcode=2008PLoSO...3.3014P |doi-access=free }}</ref>
