The white-capped dipper (Cinclus leucocephalus) is a semiaquatic passerine bird of South America. It is found in Bolivia, Colombia, Ecuador, Peru, and Venezuela. The white-capped dipper was described by the Swiss naturalist Johann Jakob von Tschudi in 1844 with the binomial Cinclus leucocephalus, which it has retained ever since. The type locality is the Junín Province in Peru. The specific epithet leucocephalus combines the Ancient Greek leukos "white" and -kephalos "-headed". Of the five species now placed in the genus, a molecular genetic study has shown that the white-capped dipper is most closely related to the other South American species, the rufous-throated dipper (Cinclus schulzii).
The white-capped dipper has these three subspecies: The sexes have the same plumage, but males are slightly larger than females. Adults of the nominate subspecies C. l. leucocephalus have a white crown and nape that sometimes have blackish brown streaks... Wikipedia →

Rare
Under 5% of wildlife watchers report a White-capped Dipper sighting in Arequipa on a given day, based on 25 verified sightings from GBIF citizen-science data. It is the 39th most-seen of the 61 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.
February and October
In those months about 10% of wildlife watchers report a White-capped Dipper in Arequipa on a given day, against under 5% in March–September and November–January, the lowest months. Those are among Arequipa's wettest months, with about 25 mm of rain a month against almost none in June.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most White-capped Dipper 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 Arequipa, in our data
Arequipa is the only city on Wallace's Line with enough records to rate White-capped Dipper sightings: under 5% of wildlife watchers there report one on a given day.
Same order: Passeriformes
The closest relatives of the White-capped Dipper that you can see in Arequipa (order Passeriformes, Perching Birds) are Chiguanco Thrush (over 90%), Rufous-collared Sparrow (about 90%) and Blue-and-white Swallow (about 80%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the White-capped Dipper is recorded against all the birds logged in Arequipa (25 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.
