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 →

With luck
About 10% of wildlife watchers report a Stripe-crowned Spinetail sighting in Mendoza on a given day, based on 55 verified sightings from GBIF citizen-science data. It is the 34th most-seen of the 69 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Stripe-crowned Spinetail is recorded against all the birds logged in Mendoza (55 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.
