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 →

Possible
About 20% of wildlife watchers report a Pine Siskin sighting in Portland on a given day, based on 9,168 verified sightings from GBIF citizen-science data. It is the 35th most-seen of the 230 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
November and December
In those months about 40% of wildlife watchers report a Pine Siskin in Portland on a given day, against about 10% in January–February and June–August, the lowest months. Those are among Portland's wettest months, with about 230 mm of rain a month against 10 mm in July.
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.
Among the best
Of the 31 cities where we can rate Pine Siskin sightings, Portland ranks 2nd at about 20%, level with the leaders once rounded. The best odds are in Toluca (México, about 20%).
Same genus: Spinus
The closest relatives of the Pine Siskin that you can see in Portland (genus Spinus, Siskins and New World Goldfinches) are Lesser Goldfinch (about 60%) and American Goldfinch (about 30%), 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 Portland (9,168 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.
