The Cuzco Warbler, *Myiothlypis chrysogaster*, is a vibrant and elusive Neotropical songbird endemic to the humid montane forests of southeastern Peru. Measuring approximately 12.5-13.5 cm (5 inches) in length and weighing around 11-12 grams, this small warbler is immediately recognizable by its striking bright yellow underparts, which extend from the throat down to the undertail coverts, contrasting sharply with its olive-green back and wings.
