Glaucidium gnoma
The Northern Pygmy Owl (*Glaucidium gnoma*) is a diminutive yet formidable raptor, measuring just 15-18 cm (6-7 inches) in length with a wingspan of 38-40 cm (15-16 inches) and weighing 50-75 grams. Its compact body is typically grayish-brown or reddish-brown above, heavily streaked with white on its underparts, and features a dark, unstreaked crown. Distinctive white eyebrows and bright yellow eyes give it an alert appearance, but its most unique field mark is the pair of black "false eyes" ...
