There are estimated to be 40 million house finches across North America, making it the second-most populous finch, just behind the American goldfinch. The house finch and the other two American rosefinches (Cassin's and purple finch) are placed in the genus Haemorhous.

Their breeding habitat is urban and suburban areas across North America, as well as various semi-open areas in the west from southern Canada to the Mexican state of Oaxaca; the population in central Chiapas may be descended from escaped cagebirds. Analyses of nest records from house finches in California spanning more than a century found that egg‐laying occurred... Wikipedia →

GBIF citizen-science records
It is estimated from how often the House Finch is recorded against all the birds logged in Monterrey (457 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.
