The superciliated wren (Cantorchilus superciliaris) is a species of bird in the family Troglodytidae. It is found in Ecuador and Peru. The superciliated wren has sometimes been treated as conspecific with the buff-breasted wren (C. leucotis) but they differ in vocalizations and ecology.
The superciliated wren is 14.5 cm (5.7 in) long. Adults of the nominate subspecies have a dark grayish brown crown, rufous-brown shoulders and back becoming redder on the rump. The tail is reddish brown with black bars. They have a prominent white supercilium, a dark brown stripe through the eye, and buffy-white cheeks. Their chin and throat are pale buffy white that darkens to the lower chest and the flanks are buffy gray. Juveniles are similar but a cooler brown in the uppersides. C. s. baroni has a more tawny lower back and rump.
The nominate superciliated wren is found in western Ecuador from Manabí Province south to Guayas Province. C. s. baroni is found from southern Ecuador's El Oro and Loja Provinces south to the departments of Ancash and Lima... Wikipedia →

Rare
Under 5% of wildlife watchers report a Superciliated Wren sighting in Guayaquil on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 122nd most-seen of the 167 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
June and December
In those months about 10% of wildlife watchers report a Superciliated Wren in Guayaquil on a given day, against under 5% in January–May and July–November, the lowest months. Those are among Guayaquil's driest months, with about 15 mm of rain a month against 220 mm in February.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Superciliated Wren 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 Guayaquil, in our data
Guayaquil is the only city on Wallace's Line with enough records to rate Superciliated Wren sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Troglodytidae
The closest relatives of the Superciliated Wren that you can see in Guayaquil (family Troglodytidae, Wrens) are Fasciated Wren (about 40%) and Southern House Wren (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Superciliated Wren is recorded against all the birds logged in Guayaquil (12 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.
