Rare
Under 5% of wildlife watchers report a Brown-Lined Owlet sighting in Baltimore on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 620th most-seen of the 705 insects 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.

Of the 2 cities where we can rate Brown-Lined Owlet sightings, Baltimore has the highest daily chance: under 5%. Next come Toronto (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Brown-Lined Owlet is recorded against all the insects logged in Baltimore (5 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.
