Zeledonzaunkönig Cantorchilus zeledoni

Small, skulking wren of foothills and lowlands along the Caribbean slope from Nicaragua south to western Panama. Found in forest edges, second-growth thickets, and brushy fields with cane grass. Heard more often than seen: song relatively short with bright phrases usually repeated a few times in quick succession. Note the bold white eyebrow, whitish breast, rich buffy flanks, and bright rusty tail barred black. Formerly known as Plain Wren.
