Rare
Under 5% of wildlife watchers report a Black-headed Siskin sighting in Mexico City on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 328th most-seen of the 332 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Black-headed Siskin in Mexico City on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Black-headed Siskin sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

Of the 3 cities where we can rate Black-headed Siskin sightings, Mexico City ranks 3rd at under 5%. The best odds are in Guatemala City (Guatemala, about 10%) and Tegucigalpa (Honduras, under 5%).
GBIF citizen-science records
It is estimated from how often the Black-headed Siskin is recorded against all the birds logged in Mexico City (5 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.
