Spotted Nothura
The most common and widespread nothura, with pale brown plumage heavily spotted with black and buff. Found in pampas grasslands, agricultural land, and open scrub across Argentina, Uruguay, Brazil, and Bolivia. Highly terrestrial; flies rarely. Calls with a rapid descending trill.
Great Tinamou
The largest regularly occurring tinamou, with brownish-grey plumage, barred wings, and a pale belly. Common in lowland Neotropical rainforest from Mexico to Bolivia. Males incubate glossy teal-colored eggs. Their haunting multi-note calls resonate through the forest, making them acoustically conspicuous yet visually elusive.
