The striped owl (Asio clamator) is a medium-sized owl with large ear tufts and a brownish-white facial disk rimmed with black. Its beak is black, and it has cinnamon-colored eyes. It has shorter, rounder wings than most of its close relatives. The upperparts are cinnamon with fine black vermiculation and heavy stripes. The underparts are pale tawny with dusky streaks. It is native to South America and parts of Central America.
The striped owl was formally described by the French ornithologist Louis Pierre Vieillot in 1808 under the binomial name Bubo clamator. The specific epithet clamator is Latin meaning "shouter". The type locality is Cayenne in French Guiana. The striped owl was at one time placed in its own genus Rhinoptynx and was then transferred to the genus Pseudoscops. A molecular study that compared mitochondrial DNA sequences indicated that it should be placed in the genus Asio. This result was confirmed by a large molecular phylogenetic study of the owls published in 2019.
The striped owl is a relatively large species with prominent tufts of elongated feathers on the crown resembling ears. It is 30–38 cm (12–15 in) long and weighs from... Wikipedia →

Under 5% of wildlife watchers report a Striped Owl sighting in Porto Alegre on a given day, based on 30 verified sightings from GBIF citizen-science data. It is the 126th most-seen of the 159 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Striped Owl in Porto Alegre on a given day, so our monthly data shows no clear season.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Striped Owl sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.

GBIF citizen-science records
It is estimated from how often the Striped Owl is recorded against all the birds logged in Porto Alegre (30 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.
