Segni di campo chiave

• Size and Shape. Look for a small, compact owl with a relatively flat head and long legs. It often appears 'squat' when perched.
• Eyes and Facial Expression. Bright yellow eyes with prominent white 'eyebrows' give it a distinctive, stern, or 'frowning' expression. No ear tufts.
• Plumage Pattern. Grey-brown upperparts heavily spotted with white/buff, and whitish underparts with bold dark streaks. This mottled pattern provides excellent camouflage.
• Perching Behavior. Often perches conspicuously on exposed sites like fence posts, telephone poles, rocks, or low branches, even during the day.
• Head Bobbing. A characteristic behavior when alert or curious is to bob its head up and down or swivel it from side to side.
• Vocalization. Listen for its distinctive, mournful 'goo-ek' or 'kiew' call, especially at dusk and dawn.
