The Rufous-rumped Antwren (Euchrepomis callinota) is a petite and elusive member of the Thamnophilidae family, characteristic of Neotropical montane forests. Measuring a mere 8-10 cm in length and weighing around 7-8 grams, its small stature makes it easily overlooked. Distinctive field marks include a generally gray head and throat, an olive-green back, blackish wings accented by two prominent pale buff to whitish wing bars, and a pale underbelly. Its most striking feature, and namesake, is ...
