Asthenes cactorum
In 3 days ~10%
The cactus canastero (Pseudasthenes cactorum) is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is endemic to Peru. The cactus canastero was long placed in genus Asthenes. Beginning in 2010 it and three other members of Asthenes were moved to the newly coined genus Pseudasthenes. Beyond that move, its taxonomy is unsettled. The International Ornithological Committee and BirdLife International's Handbook of the Birds of the World treat it as monotypic. However, the two putative taxa "appear to be products of clinal variation combined with differences in degree of plumage wear, and described characters do not permit diagnosis of individual specimens".
This article follows the monotypic species model. The cactus canastero is 13 to 14 cm (5.1 to 5.5 in) long and weighs 16 to 19 g (0.56 to 0.67 oz). The sexes have the same plumage. Adults have a pale buff supercilium, fuscous lores and stripe behind the eye, and dull buff ear coverts. Their crown and upperparts are uniform... Wikipedia →

Rare
Under 5% of wildlife watchers report a Cactus Canastero sighting in Arequipa on a given day, based on 26 verified sightings from GBIF citizen-science data. It is the 43rd most-seen of the 61 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
May and June
In those months about 10% of wildlife watchers report a Cactus Canastero in Arequipa on a given day, against under 5% in July to April, the lowest months. Those are among Arequipa's driest months, with almost no rain against 45 mm in February.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Cactus Canastero sightings with a recorded time, and nearly all 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 Cactus Canastero sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Cactus Canastero is recorded against all the birds logged in Arequipa (26 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.
