Small58 gForest

The Eurasian pygmy owl is usually red-tinged to a greyish-brown with dots on its back. The tail is generally darker than the body with five narrow, whitish bars. It has a small, short head with white to grey eyebrows and yellow eyes. It lacks the ear tufts that many other owls have. There is a white half-collar on the back of the neck. The belly is mostly white with brown speckles. The beak is a greyish-yellow and hook-shaped. In order to be able to carry larger vertebrate prey, it has evolved disproportionately large feet. The legs and toes are a brownish-yellow with black talons. Voice: The call of the Eurasian pygmy owl is much higher in pitch than what is generally perceived as a normal owl "hoot". The call of the male is a monotonous chain of clear, fluted notes spaced by about two seconds. The call of the female is similar, but higher in pitch. Before and after the mating season, both males and females make a five to seven note rise on the pitch scale.

Medium75 gShrubland

The ferruginous pygmy owl is small, typically 15 cm (5.9 in), and stocky with disproportionately large feet and talons. The crown has elongated white/buff streaks, the wing coverts have white spots, and the underparts are heavily streaked white. There are prominent white supercilia above the facial disc. There are two dark spots on the nape, often termed "false eyes" by birders. Otherwise, its overall color is highly variable, ranging from grey-brown with a black-and-white barred tail to rich rufous with a uniform rufous tail. Voice: The call is a whistled hoo-hoo-hoo-hoo, usually in E flat. It is easily imitated, and is used by birdwatchers to attract small birds intent on mobbing the pygmy owls.
