Similar species

Apparantly, this species cannot be safely separated from Pernambuco Pygmy-Owl on plumage characters (even when evaluating specimens from a museum) but only on voice.


South America: found in east Paraguay to south-eastern Brazil and north-eastern Argentina (Misiones).


This is a monotypic species[1].

It has been claimed that the scientific name of this species has been misapplied and that it really should be called Glaucidium sicki. No world wide checklists have followed suit and Opus is therefore not changing at this time either.


Evergreen rain forest and forest edge.



There is little detailed information; they are known to take insects, small lizards and small birds.


They nest in a tree cavity. There is little more information available.
