Rare
Under 5% of wildlife watchers report a Tufted Globetail sighting in Montreal on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 556th most-seen of the 926 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 Tufted Globetail in Montreal on a given day, so our monthly data shows no clear season.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Tufted Globetail sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 14 cities where we can rate Tufted Globetail sightings, Montreal ranks 12th at under 5%, level with the leaders once rounded. The best odds are in Boston (United States, under 5%), Minneapolis [Saint Paul] (United States, under 5%) and Washington (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Tufted Globetail is recorded against all the insects logged in Montreal (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.
