The American white pelican (Pelecanus erythrorhynchos) is a large aquatic soaring bird from the order Pelecaniformes. It breeds in interior North America, moving south and to the coasts, as far as Costa Rica, in winter. The American white pelican was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the other pelicans in the genus Pelecanus. He coined the binomial name Pelecanus erythrorhynchos. Gmelin based his description on the "rough-billed pelican" that had been described in 1785 by the English ornithologist John Latham. Latham had access to three specimens that had been brought to London from New York and the Hudson Bay area of North America. The scientific name means "red-billed pelican", from the Latin term for a pelican, Pelecanus, and erythrorhynchos, derived from the Ancient Greek words erythros (ἐρυθρός) 'red' + rhynchos (ῥύγχος) 'bill'. The species is monotypic: no subspecies are recognised.
The American white pelican rivals the trumpeter swan, with a similar overall length, as one of the longest birds native to North America... Wikipedia →

Possible
About 20% of wildlife watchers report an American White Pelican sighting in Denver on a given day, based on 8,258 verified sightings from GBIF citizen-science data. It is the 44th most-seen of the 299 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
April and May
In those months about 30% of wildlife watchers report an American White Pelican in Denver on a given day, against under 5% in December to February, the lowest months. Those are among Denver's wettest months, with about 55 mm of rain a month against 15 mm in January.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most American White Pelican 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 32
Of the 32 cities where we can rate American White Pelican sightings, Denver ranks 3rd at about 20%. The best odds are in León (México, about 30%) and Mesa (United States, about 20%).
Same order: Pelecaniformes
The closest relatives of the American White Pelican that you can see in Denver (order Pelecaniformes, Pelicans, Herons, Ibises, and Allies) are Great Blue Heron (about 20%), Snowy Egret (about 20%) and Black-crowned Night Heron (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the American White Pelican is recorded against all the birds logged in Denver (8,258 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.
