The trumpeter swan (Cygnus buccinator), or simply the trumpeter, is a species of swan found in North America. The heaviest living bird native to North America, it is also the largest extant species of waterfowl, with a wingspan of 185 to 304.8 cm (6 ft 2 in to 10 ft 2 in). It is the American counterpart and a close relative of the whooper swan (Cygnus cygnus) of Eurasia and has even been considered the same species by some authorities. By 1933, fewer than 70 wild individuals were known to exist; extinction seemed imminent until aerial surveys discovered a Pacific population of several thousand trumpeter swans around Alaska's Copper River. Careful reintroductions by wildlife agencies and the Trumpeter Swan Society gradually restored the North American wild population to over 46,000 birds by 2010.
The trumpeter swan was formally described in 1831 by the Scottish naturalist John Richardson in the fourth volume of American Ornithology; or, The Natural History of Birds Inhabiting the United States by Alexander Wilson and Charles Bonaparte. Richardson coined the current binomial name Cygnus buccinator. A description by Richardson was also published in Fauna Boreali-Americana... Wikipedia →

Likely
About 40% of wildlife watchers report a Trumpeter Swan sighting in Anchorage on a given day, based on 1,647 verified sightings from GBIF citizen-science data. It is the 13th most-seen of the 138 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.
April and July
In those months about 60% of wildlife watchers report a Trumpeter Swan in Anchorage on a given day, against under 5% in December and January, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Trumpeter Swan sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 12 cities where we can rate Trumpeter Swan sightings, Anchorage has the highest daily chance: about 40%. Next come Minneapolis [Saint Paul] (United States, about 10%) and Toronto (Canada, about 10%).
GBIF citizen-science records
It is estimated from how often the Trumpeter Swan is recorded against all the birds logged in Anchorage (1,647 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.
