Any time of year
In every month with enough records, under 5% of wildlife watchers report a North American Common Gray in New York City on a given day, so our monthly data shows no clear season.

GBIF citizen-science records
It is estimated from how often the North American Common Gray is recorded against all the insects logged in New York City (9 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.
