The small rufous-sided pygmy tyrant is a member of the family Tyrannidae, a name taken from the Greek word tyrannas, meaning ‘lord’ or ‘ruler’, and refers to their aggressive behaviour (3). The plumage is mostly a drab brown, slightly darker on the wings, and, as the name suggest, the sides are a warm orange. The long, brown tail feathers are edged in yellowy-orange. The underparts are pale yellow, the throat is white, and the light brown face has a short, whitish ‘eyebrow’, or supercilium. The upper part of the beak is black, whilst the lower part is flesh-coloured, and the eyes are dark brown (2).
