Rare
Under 5% of wildlife watchers report an American Bird's-Wing sighting in Toronto on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 1410th most-seen of the 1689 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an American Bird's-Wing in Toronto on a given day, so our monthly data shows no clear season.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most American Bird's-Wing sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen at night.
Only Toronto, in our data
Toronto is the only city on Wallace's Line with enough records to rate American Bird's-Wing sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Noctuidae
The closest relatives of the American Bird's-Wing that you can see in Toronto (family Noctuidae, Cutworm Moths and Allies) are American Dagger (about 10%), Large Yellow Underwing (about 10%) and Armyworm Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the American Bird's-Wing is recorded against all the insects logged in Toronto (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.
