Rare
Under 5% of wildlife watchers report a Eurasian Baskettail sighting in Nizhny Novgorod on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 293rd most-seen of the 405 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.
May
In that month about 10% of wildlife watchers report a Eurasian Baskettail in Nizhny Novgorod on a given day, against under 5% in June to April, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Eurasian Baskettail 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 4 cities where we can rate Eurasian Baskettail sightings, Nizhny Novgorod ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Kyiv (Ukraine, under 5%).
GBIF citizen-science records
It is estimated from how often the Eurasian Baskettail is recorded against all the insects logged in Nizhny Novgorod (6 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.
