The Canada warbler (Cardellina canadensis) is a small boreal songbird of the New World warbler family (Parulidae). It summers in Canada and northeastern United States and winters in northern South America. In 1760 the French zoologist Mathurin Jacques Brisson included a description of the Canada warbler in his Ornithologie based on a specimen collected in Canada. He used the French name Le gobe-mouche cendré de Canada and the Latin name Muscicapa Canadensis Cinerea. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added 240 species that had been previously described by Brisson. One of these was the Canada warbler. Linnaeus included a brief description, coined the binomial name Muscicapa canadensis, and cited Brisson's work. The species is now placed in the genus Cardellina that was introduced by the French naturalist Charles Lucien Bonaparte in 1850. The species is monotypic.
The Canada warbler is sometimes called the "necklaced warbler... Wikipedia →

Rare
Under 5% of wildlife watchers report a Canada Warbler sighting in Havana on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 151st most-seen of the 183 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
September
In that month about 10% of wildlife watchers report a Canada Warbler in Havana on a given day, against under 5% in October to August, the lowest months. That is one of Havana's wettest months, with about 100 mm of rain against 25 mm in March.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Canada Warbler 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 Canada Warbler sightings, Havana ranks 19th at under 5%, level with the leaders once rounded. The best odds are in Chicago (United States, under 5%), Bogota (Colombia, under 5%) and New York City (United States, under 5%).
Same family: Parulidae
The closest relatives of the Canada Warbler that you can see in Havana (family Parulidae, New World Warblers) are Palm Warbler (about 50%), American Redstart (about 40%) and Northern Parula (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Canada Warbler is recorded against all the birds logged in Havana (16 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.
