Pulsatrix is sometimes considered a full species, Short-browed Owl.


Dense forest, but hunts in the semi-open and savanna with large trees, also in clearings and along forest edges.


This is nocturnal species of mature forests.


The nest is an unlined tree cavity, laying two white eggs.


It preys on mammals (up to 90% of its food by mass); in addition, it utilizes a variety of other food sources including other vertebrates and invertebrates. Among birds, it will also take smaller owls.


The call is a deep hooting BOO Boo boo boo boo becoming softer and faster.
