The Chaco sparrow (Rhynchospiza strigiceps), formerly known as the stripe-capped sparrow, is a species of bird in the family Passerellidae. It is found in Argentina and Paraguay. The current Chaco sparrow was originally one of two subspecies of the then stripe-capped sparrow (Aimophila strigiceps). A 2009 publication restored the genus Rhynchospiza and moved A. stolzmanii and A. strigiceps to that genus. A 2019 publication split Rhynchospiza dabbenei from R. strigiceps. Based on the 2019 publication, in June 2020 the South American Classification Committee (SACC) of the American Ornithological Society (AOS) split R. dabbenei as the Yungas sparrow and renamed R. strigiceps sensu stricto as the Chaco sparrow. The International Ornithological Congress (IOC) followed suit in January 2021.
The Chaco sparrow is the smaller of the two former subspecies that were split. Its upper parts are light brown with darker streaks and varying amounts of rust and gray. It is pale gray below blending to buff on the flanks. The head is gray with cinnamon crown and postocular stripes, pale lores, and a black moustachial stripe. Wikipedia →

With luck
About 10% of wildlife watchers report a Stripe-capped Sparrow sighting in Cordoba on a given day, based on 157 verified sightings from GBIF citizen-science data. It is the 63rd most-seen of the 176 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
May
In that month about 20% of wildlife watchers report a Stripe-capped Sparrow in Cordoba on a given day, against under 5% in July, September and November, the lowest months. That is one of Cordoba's driest months, with about 20 mm of rain against 130 mm in February.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Stripe-capped Sparrow 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 Stripe-capped Sparrow sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Stripe-capped Sparrow is recorded against all the birds logged in Cordoba (157 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.
