About These Birds
Tepui Tinamou
Tinamú de Ptaritepui (Crypturellus ptaritepui) — Tinamú endémico de los tepuyes de Venezuela, en especial del macizo de Ptaritepui. Muy poco conocido y difícil de estudiar por su hábitat inaccesible.
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.
