With luck
About 10% of wildlife watchers report an Aurora Bluetail sighting in Auckland on a given day, based on 36 verified sightings from GBIF citizen-science data. It is the 191st most-seen of the 689 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
September–October and December–April
In those months about 10% of wildlife watchers report an Aurora Bluetail in Auckland on a given day, against under 5% in May–August and November, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Aurora Bluetail 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 5 cities where we can rate Aurora Bluetail sightings, Auckland ranks 4th at about 10%, level with the leaders once rounded. The best odds are in Perth (Australia, about 10%), Brisbane (Australia, about 10%) and Melbourne (Australia, about 10%).
GBIF citizen-science records
It is estimated from how often the Aurora Bluetail is recorded against all the insects logged in Auckland (36 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.
