Mountain Pygmy-Owl © fineartamerica.com

Sometimes considered to form superspecies with Eurasian Pygmy-Owl (Glaucidium passerinum), Collared Owlet (Glaucidium brodiei), Pearl-spotted Owlet (Glaucidium perlatum) and Northern Pygmy-Owl (Glaucidium californicum), and including recently separated Guatemalan Pygmy-Owl (Glaucidium cobanense) and Sjostedt's Owlet (Glaucidium sjostedti), but DNA evidence clearly shows that Eurasian Pygmy-Owl (Glaucidium passerinum) and Northern Pygmy-Owl (Glaucidium californicum) are not closely related. Formerly considered to include last three as subspecies, but these split on basis of vocalizations and/or DNA evidence. Perhaps closely related to Costa Rican Pygmy-Owl (Glaucidium costaricanum), which has recently been considered conspecific with present species by some authors.

The following 7 subspecies are recognised:

• gnoma Wagler, 1832   -  South-western Arizona (USA) to central Mexico.
• grinnelli Ridgway, 1914   -  South-eastern Alaska through coastal British Columbia south to coastal western USA (Washington, Oregon, California). Considered by some authors to be a subspecies of Northern Pygmy-Owl (Glaucidium californicum).
• swarthi Grinnell, 1913   -  Vancouver I. Considered by some authors to be a subspecies of Northern Pygmy-Owl (Glaucidium californicum).
• californicum Sclater, PL, 1857   -  British Columbia and Alberta to western USA (south to Nevada and California) and north-western Mexico (northern Sonora, north-western Chihuahua). Considered by some authors to be a distinct species, Northern Pygmy-Owl (Glaucidium californicum).
• pinicola Nelson, 1910   -  Western USA (Idaho and Montana south to Arizona and New Mexico, east to Colorado). Considered by some authors to be a subspecies of Northern Pygmy-Owl (Glaucidium californicum).
• cobanense Sharpe, 1875   -  Southern Mexico to Guatemala and Honduras. Considered by some authors to be a distinct species, Guatemalan Pygmy-Owl (Glaucidium cobanense).
• hoskinsii Brewster, 1888   -  Baja California (Mexico). Considered by some authors to be a distinct species, Cape Pygmy-Owl (Glaucidium hoskinsii).
