Marcas de campo essenciais

• Plumage Pattern. Look for the striking contrast of a creamy-white head and underparts with a broad black mask across the eyes and dark brown upperparts. This pattern is unique among Neotropical raptors.
• Vocalization. Listen for its unmistakable, loud, human-like 'laughing' call, especially at dawn and dusk. This is often the first indication of its presence.
• Perching Behavior. Observe its characteristic upright posture when perched conspicuously on high, exposed branches, often at the edge of a forest or clearing.
