Rare
Under 5% of wildlife watchers report a Boreal Burying Beetle sighting in Portland on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 316th most-seen of the 507 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Boreal Burying Beetle in Portland on a given day, so our monthly data shows no clear season.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Boreal Burying Beetle sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 3 cities where we can rate Boreal Burying Beetle sightings, Portland ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Vancouver (Canada, under 5%) and Seattle (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Boreal Burying Beetle is recorded against all the insects logged in Portland (11 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.
