The spotted owl is under pressure from habitat destruction throughout its range, and is currently classified as a near-threatened species.
The spotted owl has an average length of 43 cm (17 in), wingspan of 114 cm (45 in), and weight of 600 g (1.3 lb). Its eggs are a little over 50 mm (2.0 in) long, and are white and smooth with a slightly grainy texture. The spotted owl is similar in appearance to the barred owl, but has cross-shaped markings on the underparts, whereas the barred owl is alternately barred on the breast and streaked on the belly.

Possible
About 20% of wildlife watchers report a Spotted Owl sighting in Sequoia and Kings Canyon National Parks on a given day, based on 45 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 40th most-seen of the 152 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
March, June–July and September–October
In those months about 20% of wildlife watchers report a Spotted Owl in Sequoia and Kings Canyon National Parks on a given day, against under 5% in April and November–February, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Spotted Owl sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Among the best
Of the 4 parks where we can rate Spotted Owl sightings, Sequoia and Kings Canyon National Parks ranks 2nd at about 20%, level with the leaders once rounded. The best odds are in Zion National Park (United States, about 20%).
GBIF citizen-science records
It is estimated from how often the Spotted Owl is recorded against all the birds logged in Sequoia and Kings Canyon National Parks (45 verified sightings from 2019 to 2026), 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.
