The green-tailed towhee (Pipilo chlorurus) is a species of bird in the family Passerellidae, the New World sparrows. It is found in the western United States and much of Mexico. The formal description of the green-tailed towhee is credited to Audubon, lthough the bird's description was written by John Townsend in a letter to him. Audubon gave this bird the binomial Fringilla chlorura and the English name "green-tailed sparrow". Because the species' wing shape and some other characteristics are somewhat distinctive, various authors placed it genera Oreospiza, Chlorura, or Oberholseria before it settled into its current Pipilo.
The genus (Pipilo) of the green-tailed towhee is monotypic. The green-tailed towhee is about 18 cm (7.1 in) long and weighs on average about 29 g (1.0 oz). Though the sexes have essentially the same plumage, females tend to be slightly duller than males. Adults have a reddish brown crown, a white spot above the lores, and a white "moustache" and throat on an otherwise gray head. Their hindneck, back, and scapulars are yellowish olive with grayish olive edges on the feathers. Their rump and uppertail coverts are grayish... Wikipedia →

Possible
About 20% of wildlife watchers report a Green-tailed Towhee sighting in Rocky Mountain National Park on a given day, based on 2,145 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 31st most-seen of the 223 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.
June and July
In those months about 40% of wildlife watchers report a Green-tailed Towhee in Rocky Mountain National Park on a given day, against under 5% in October to April, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Green-tailed Towhee sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 16
Of the 16 parks where we can rate Green-tailed Towhee sightings, Rocky Mountain National Park ranks 3rd at about 20%. The best odds are in Cabo Pulmo National Park (Mexico, about 40%) and Grand Teton National Park (United States, about 30%).
GBIF citizen-science records
It is estimated from how often the Green-tailed Towhee is recorded against all the birds logged in Rocky Mountain National Park (2,145 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.
