The Variable Hawk is a large and widespread raptor of South America, known for its remarkable plumage variation, ranging from light to dark morphs. It is a powerful hunter of diverse open habitats.
Where to spot
Widespread across South America, primarily in the Andes and Patagonia. It inhabits open grasslands, agricultural areas, woodlands, and arid scrublands, from sea level to high altitudes.
How to spot
Observe its broad, strong wings and powerful flight. Due to plumage variation, focus on shape, size, and flight style. Listen for its loud, piercing calls.
When to spot
Active throughout the day, often seen soaring high on thermals or perched conspicuously. Observable year-round in its resident range.

Its common name reflects the incredible plumage polymorphism, where individuals can range from almost entirely black to largely white, making identification challenging without familiarity with local variations.
