Tan, heavily patterned tinamou with a down-curved bill. Found in montane scrub and grasslands, including around forest edges. Where it overlaps with the similar Curve-billed Tinamou, note Andean’s colder brown coloration and slightly reduced patterning below. Smaller than the similar Ornate Tinamou, with a larger bill. Often undetected until it flushes explosively from underfoot. Listen for its simple call, a high, piercing, rising whistle: “tuEEE!”
