Birds to compare
Northern Saw-whet Owl
Aegolius acadicus
Key differences
The Northern Saw-whet Owl is smaller, has a more reddish-brown plumage, and lacks the prominent dark border around the facial disc. Its facial disc is less distinctly outlined, and its crown is streaked, not spotted. The Boreal Owl's facial disc is whiter and more defined, giving it a 'surprised' look, and its overall coloration is grayer-brown.
Great Gray Owl
Strix nebulosa
Key differences
While both inhabit boreal forests, the Great Gray Owl is vastly larger (the largest owl in North America by length) and has a much larger, grayer facial disc with concentric rings and a prominent 'bow-tie' pattern under its beak. The Boreal Owl is tiny in comparison.
Pygmy Owls (e.g., Eurasian Pygmy Owl)
Glaucidium passerinum
Key differences
Pygmy owls are much smaller, have a more compact body, and typically have 'false eyes' on the back of their head. Their flight is more direct and less undulating. Boreal Owls are larger, lack false eyes, and have a distinct facial disc.
