Cardinale rosso

Tassonomia

The northern cardinal was described by Carl Linnaeus in the 1758 10th edition of Systema Naturae. It was originally categorized as Loxia cardinalis, a genus which now contains only crossbills. In 1838, it was recategorized as Cardinalis virginianus. In 1918, the scientific name was sometimes replaced with Richmondena cardinalis. In 1983, the scientific name was changed again to Cardinalis cardinalis and the common name was changed to "northern cardinal", to avoid confusion with the several other species also termed cardinals.<p>The cardinal is named after cardinals of the Roman Catholic Church, who wear distinctive red robes and caps. The term "northern" in the common name refers to its range, as it is the northernmost cardinal species known.

Areale e habitat

Northern cardinals are numerous across the eastern United States from the southern half of Maine to Minnesota to the Texas-Mexico border and in Canada in the southern portions of Ontario, Quebec, New Brunswick and Nova Scotia, all the way east to Cape Breton Island. Its range also extends south through Mexico to the Isthmus of Tehuantepec, northern Guatemala, and northern Belize. An allopatric population is found on the Pacific slope of Mexico from Jalisco to Oaxaca (this population is not shown on the range map). The species was introduced to Bermuda in 1700. It has also been introduced in Hawaii, southern California, and southern Arizona. Its natural habitat is in woodlands, gardens, shrublands, and wetlands.<p>In 1929, Forbush described the species as rare, and by 1955 Griscom reported the bird to be "pushing northward" when recorded annually at feeding stations. Audubon data shows that the population has grown rapidly in Massachusetts since 1960. In Massachusetts, the species is most abundant in the east, especially in areas where dense cover is interspersed with open areas, such as woodland edges, brushy fields, wooded wetlands, parks, and suburban areas. They tend to avoid extensive woodlands.
