Small, virtually tailless warbler of montane forest. The facial pattern is distinct, with a rufous-brown cap and eye-stripe and a contrasting white eyebrow and throat. Found in thick areas of montane humid forest, especially tangled undergrowth and vines. Sometimes joins mixed-species flocks. The song is a quiet series of up-and-down twitters. Chapin’s Crombec is very similar, but White-browed is easily separated by its broad white eyebrow.
