Small bird, its average size is 21.5 to 28.5 cm (males) and 22 to 25 cm (females). It weighs between 110 and 285 g (males) and between 150 and 265 g (females). It has a round head, without plumes and the eyes are arranged side by side, in the same plane. The eyebrows are white and the eyes are yellow. The coloration is earthy, mimetic, and may present plumage in rusty tones caused by purple earth soils (adventitious coloration). Unlike most owls, the male is slightly larger than the female and females are normally darker than males, particularly on the face. It has a smooth and silent flight. She has to turn her neck, because her big eyes are arranged side by side in the same plane. This frontal arrangement gives the owl binocular vision (it sees an object with both eyes at the same time). This means that the owl can see objects in three dimensions, that is, height, width and depth. The eyes of the burrowing owl are very large, in some subspecies of owls they are even larger than the brain itself, in order to improve its efficiency in low light conditions, better capturing and processing the available light.
