Any time of year
In every month with enough records, under 5% of wildlife watchers report a Spotted Harrier in Perth on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Spotted Harrier sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 cities where we can rate Spotted Harrier sightings, Perth ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Brisbane (Australia, under 5%).
GBIF citizen-science records
It is estimated from how often the Spotted Harrier is recorded against all the birds logged in Perth (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.
