Cassin's finch (Haemorhous cassinii) is a bird in the finch family, Fringillidae. This species and the other "American rosefinches" are placed in the genus Haemorhous. This bird was named after John Cassin, who was a curator at the Philadelphia Academy of Natural Sciences.
Measurements: Length: 6.3 in (16 cm) Weight: 0.8–1.2 oz (24–34 g) Wingspan: 9.8–10.6 in (25–27 cm) Adults have a short forked brown tail and brown wings. They have a longer bill than the purple finch. Adult males are raspberry red on the head, breast, back and rump; their back and under-tail are streaked. Adult females have light brown upper-parts and light underparts with brown streaks throughout; their facial markings are less distinct than those of the female purple finch. They can have brown, red, and white eyes.
Their breeding habitat is coniferous forest in mountains of western North America as far south as northern New Mexico and Arizona; also Southern California near Baja California. They nest in large conifers. They move to lower elevations in winter.
Northernmost breeding birds migrate south, as do some birds throughout the range of the species... Wikipedia →

Rare
Under 5% of wildlife watchers report a Cassin's Finch sighting in Big Bend National Park on a given day, based on 28 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 213th most-seen of the 270 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 Cassin's Finch in Big Bend National Park 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 Cassin's 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.
13th of 14
Of the 14 parks where we can rate Cassin's Finch sightings, Big Bend National Park ranks 13th at under 5%. The best odds are in Yosemite National Park (United States, about 20%), Rocky Mountain National Park (United States, about 20%) and Yellowstone National Park (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Cassin's Finch is recorded against all the birds logged in Big Bend National Park (28 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.
