The stripe-crowned spinetail (Cranioleuca pyrrhophia) is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Argentina, Bolivia, Brazil, Paraguay, and Uruguay. Genetic data published in 2011 found that the stripe-crowned spinetail and the pallid spinetails (C. pallida) are sister species, and that the two are closely related to the olive spinetail (C. obsoleta). Some earlier work supported treating the stripe-crowned, olive, and Bolivian spinetail (C. henricae) as a superspecies. The stripe-crowned and olive spinetails hybridize in southern Brazil and there have been suggestions that they are conspecific.
The stripe-crowned spinetail is 13 to 16 cm (5.1 to 6.3 in) long and weighs 10 to 16 g (0.35 to 0.56 oz). It is a smallish member of genus Cranioleuca and has unique crown and tail patterns. The species shows considerable plumage variation following Gloger's rule. The sexes have the same plumage... Wikipedia →

Rare
Under 5% of wildlife watchers report a Stripe-crowned Spinetail sighting in Montevideo on a given day, based on 102 verified sightings from GBIF citizen-science data. It is the 79th most-seen of the 178 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
April–August and October
In those months about 10% of wildlife watchers report a Stripe-crowned Spinetail in Montevideo on a given day, against under 5% in September and November–March, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Stripe-crowned Spinetail sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 5
Of the 5 cities where we can rate Stripe-crowned Spinetail sightings, Montevideo ranks 2nd at under 5%. The best odds are in Mendoza (Argentina, about 10%).
Same family: Furnariidae
The closest relatives of the Stripe-crowned Spinetail that you can see in Montevideo (family Furnariidae, Ovenbirds and Woodcreepers) are Rufous Hornero (about 90%) and Narrow-billed Woodcreeper (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Stripe-crowned Spinetail is recorded against all the birds logged in Montevideo (102 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.
