The pine siskin (Spinus pinus) is a North American bird in the finch family. It is a migratory bird with an extremely sporadic winter range. The pine siskin is currently listed as a species of Least Concern on the IUCN Red List.
The pine siskin was formally described in 1810 by the American ornithologist Alexander Wilson under the binomial name Fringilla pinus. The specific epithet pinus is the Latin word for a "pine-tree". The type locality is Philadelphia, Pennsylvania. The pine siskin is now placed in the genus Spinus that was introduced in 1816 by the German naturalist Carl Ludwig Koch in 1816.
Three subspecies are recognised: In both sexes, total length can range from 11–14 cm (4.3–5.5 in), with a wingspan of 18–22 cm (7.1–8.7 in) and a weight of 12–18 g (0.42–0.63 oz). Adults are brown on the upperparts and pale on the underparts, with heavy streaking throughout... Wikipedia →

Likely
About 40% of wildlife watchers report a Pine Siskin sighting in Reserva de la Biosfera Mariposa Monarca on a given day, based on 75 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 15th 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 February
In those months about 50% of wildlife watchers report a Pine Siskin in Reserva de la Biosfera Mariposa Monarca on a given day, against about 20% in October and December, the lowest months. Those are among Reserva de la Biosfera Mariposa Monarca's driest months, with about 25 mm of rain a month against 270 mm in July. April and June–September have too few records to rate.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Pine 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.
5th of 38
Of the 38 parks where we can rate Pine Siskin sightings, Reserva de la Biosfera Mariposa Monarca ranks 5th at about 40%. The best odds are in Banff National Park (Canada, about 60%), Jasper National Park (Canada, about 60%) and Glacier National Park (United States, about 50%). All parks ranked.
Same genus: Spinus
The closest relatives of the Pine Siskin that you can see in Reserva de la Biosfera Mariposa Monarca (genus Spinus, Siskins and New World Goldfinches) are 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 Pine Siskin is recorded against all the birds logged in Reserva de la Biosfera Mariposa Monarca (75 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.
