The house finch (Haemorhous mexicanus) is a North American bird in the finch family. It is native to Mexico and southwestern United States, but has since been introduced to the eastern part of North America and Hawaiʻi, and is found year-round in almost all parts of the United States and most of Mexico, with breeding grounds well into Canada as far north as northern Alberta. 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.
House finches are mainly permanent residents throughout their range; some birds migrate to the south, with adult females moving longer distances than males. 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 →

Likely
About 40% of wildlife watchers report a House Finch sighting in Reserva de la Biosfera Mariposa Monarca on a given day, based on 108 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 12th most-seen of the 103 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
January and October
In those months about 50% of wildlife watchers report a House Finch in Reserva de la Biosfera Mariposa Monarca on a given day, against about 30% in May and November, the lowest months. Those are among Reserva de la Biosfera Mariposa Monarca's driest months, with about 60 mm of rain a month against 270 mm in July. April and June–September have too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most House Finch sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
10th of 36
Of the 36 parks where we can rate House Finch sightings, Reserva de la Biosfera Mariposa Monarca ranks 10th at about 40%. The best odds are in Saguaro National Park (United States, about 70%), Bahía de Loreto National Park (Mexico, about 70%) and Channel Islands National Park (United States, about 70%). All parks ranked.
Same family: Fringillidae
The closest relatives of the House Finch that you can see in Reserva de la Biosfera Mariposa Monarca (family Fringillidae, Finches, Euphonias, and Allies) are Pine Siskin (about 40%), Lesser Goldfinch (about 30%) and Black-headed Siskin (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the House Finch is recorded against all the birds logged in Reserva de la Biosfera Mariposa Monarca (108 verified sightings from 2019 to 2026), 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.
