The brown-capped whitestart or brown-capped redstart (Myioborus brunniceps) is a species of bird in the family Parulidae, the New World warblers. It is found in Argentina and Bolivia. The brown-capped whitestart was formally described in 1837 with the binomial Setophaga brunniceps.
The brown-capped whitestart is monotypic. What are now the three subspecies of the tepui whitestart (M. castaneocapilla) were previously considered subspecies of the brown-capped. The brown-capped whitestart is about 13 cm (5.1 in) long and weighs 8.5 to 11 g (0.30 to 0.39 oz). The sexes have the same plumage. Adults have a mostly gray head with a rufous crown, a whitish stripe above the lores, and white crescents above and below the eye. Their upperparts and wings are mostly gray with an olive mantle. Their tail is black with much white on the outer feathers. Their throat and most underparts are yellow and their undertail coverts white. They have a dark iris, a blackish bill, and blackish legs and feet. Juveniles have a brownish gray head and upperparts, a buffy-brown throat and breast, and a pale yellow belly.

Rare
Under 5% of wildlife watchers report a Brown-capped Redstart sighting in Cordoba on a given day, based on 87 verified sightings from GBIF citizen-science data. It is the 90th most-seen of the 176 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
April to August
In those months about 10% of wildlife watchers report a Brown-capped Redstart in Cordoba on a given day, against under 5% in September to March, the lowest months. Those are among Cordoba's driest months, with about 20 mm of rain a month against 130 mm in February.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most Brown-capped Redstart sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Cordoba, in our data
Cordoba is the only city on Wallace's Line with enough records to rate Brown-capped Redstart sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Brown-capped Redstart is recorded against all the birds logged in Cordoba (87 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
