About the Russet-bellied Spinetail

The russet-bellied spinetail (Synallaxis zimmeri) is a Vulnerable species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is endemic to Peru. The russet-bellied spinetail appears to have no close relatives within genus Synallaxis and some authors have suggested that it deserves its own genus.

The russet-bellied spinetail is monotypic. The russet-bellied spinetail is 16.5 to 17 cm (6.5 to 6.7 in) long and weighs 12 to 14 g (0.42 to 0.49 oz). The sexes have the same plumage. Adults have a faint gray-white supercilium, a distinct but broken white eyering, and blackish lores on an otherwise gray face. Their crown is gray, their back and rump olivaceous gray, and their uppertail coverts bright rufous. Their wing coverts are almost chestnut and the flight feathers brownish. Their tail's central pair of feathers are dark fuscous; the feathers become progressively more rufous to the outermost. Their chin is ashy-gray to white, throat grayish brown, and their upper breast grayish brown with faint paler streaks. The rest of their underparts are rufous; that color is darkest on the undertail coverts. Their iris is black... Wikipedia →
