Recently proposed splits for the family Typical Owls

Of all the pages in this splits collection, I am least certain about the taxa mentioned on this page, especially for the genera Otus and Glaucidium.

At present, the information on the Otus species is mostly based on König, Weick & Becking's book, as cited.
It remains to be seen how many of their taxonomic proposals will de adopted in the future.

The Magellanic Horned Owl differs from the Great Horned Owl in its smaller size (also esp. in bill and talons), much smaller ear-tufts and denser barring on underparts.  The authors were lead to the differences through different local names for this form (called "Tucúquere" in Chile) and the lowland race B. v. nacurutu (called "Ñacurutú" in Argentina). These local names turned out to be indeed suggestive of the typical advertising calls of these forms.

B. magellanicus is monotypic: the authors clearly separate it from nacurutu, but their discussion also suggests strongly the unlikeliness that the form nigrescens (now and still in virginianus) belongs to it.

Sequence analysis of the mitochondrial cytochrome-b gene (960 base pairs) identified a genetic distance of 1.6% between magellanicus and nacurutu.
