As a rump, a number of genera from the family of the actual owls (Strigidae) are called. In a narrower sense, "owls" are especially those of the genus Strix.
The differentiation into the terms owls and owls is a peculiarity of the German language and has no equivalent in the sense of a zoological classification. Both names have a noisy origin, referring to the plaintive and howling calls of these birds. Under both names are large and small species, as well as those with and without spring ears. Thus, the German separation does not correspond to that in the French language, in which Chouette owls without feather ears and Hibou ear-owls are called.
