Sooty-fronted Spinetail
Synallaxis frontalis
The sooty-fronted spinetail is 14 to 16 cm (5.5 to 6.3 in) long and weighs 11 to 17 g (0.39 to 0.60 oz). The sexes have the same plumage. Adults have a thin brownish line through the eye on an otherwise brownish gray face. Their forecrown ("front") is dark gray-brown, their hindcrown and nape dark rufous, and their back, rump and uppertail coverts brown with a rufescent tinge. Their wing coverts are dark rufous and their flight feathers tawny-rufous with dusky tips. Voice: What appears to be the sooty-fronted spinetail's song is variously described as " 'ka-kwee-éék', 'ka-kweek', 'pi-whéé', or 'ja-coo-éé' ", a "very high 2-noted 'du-Twee' ", and "a slow, deliberate teeoopooee". This vocalization is often given for long periods. It also makes a " 'sew-kli' or 'chi-cli', and ated nasal 'hoint'or 'hoít' ".

Wren-like Rushbird
Phleocryptes melanops
The wren-like rushbird is 13 to 14 cm (5.1 to 5.5 in) long and weighs 11 to 16 g (0.39 to 0.56 oz). It is a small furnariid whose plumage closely resembles that of the wholly unrelated marsh wren (Cistothorus palustris). It has a longish slightly decurved bill. The sexes' plumages are essentially alike though females are slightly paler than males. Adults of the nominate subspecies P. m. melanops have a wide buff supercilium, grayish lores, a dark brown band behind the eye, mottled dark brown ear coverts, and a buff malar area. Their crown is blackish with wide brown streaks. Voice: In much of its range, the wren-like rushbird's song is a "repeated mechanical ticking, repeated several times per second, sometimes for several minutes, often ending with trill like that of cicada". One author describes it as sounding "like an idling motor, with the throttle occasionally opened". The song of the Andean population is "similar but with more strident tones".
