Subspecies
Glaucidium jardinii (Sibley and Monroe 1990, 1993) has been split into Costa Rican Pygmy-Owl (Glaucidium costaricanum) and Andean Pygmy-Owl (Glaucidium jardinii) following AOU (2000).
Has recently been considered by some authors as conspecific with Mountain Pygmy-Owl (Glaucidium gnoma). Probably related to the recently discovered Cloudforest Pygmy-Owl (Glaucidium nubicola).
