Taxonomy and systematics edit In

Joseph Sabine first named the black-billed magpie Corvus Hudsonius in 1823. [2] Because of their similar appearances, it was thought that the species in earlier sightings before it was described was the Eurasian magpie (Pica pica). The black-billed magpie was assigned to subspecies P due to its smaller stature and longer tail and wings. pica hudsonia. The specific name Hudsonia is named after the English explorer Henry Hudson, while the generic name Pica is the Latin word for magpie. [3].

The term “magpie” is derived from the combination of Margaret’s nickname, “Mag,” and the Middle English term for the Eurasian magpie, “pie.” The magpie’s vocalizations were thought to resemble a person chatting, so the name Margaret was coined in the early 15th century to refer to its chattiness. [4].

Before mtDNA studies revealed a relatively high divergence between the two species, the black-billed magpie and the Eurasian magpie were widely believed to be conspecific. Additionally, it was demonstrated that the black-billed magpie and the yellow-billed magpie (Pica nuttalli) of California were more closely related. Further evidence that black-billed magpies are a distinct species is provided by the observation that they differ from Eurasian magpies in their vocalizations and social behaviors. [6][7] The American Ornithologists Union identified Pica hudsonia, the black-billed magpie, as a distinct species in 2000. [8].

Based on fossil evidence, the ancestral North American magpie crossed the Bering land bridge and arrived in its current range sometime in the mid-Pliocene, or about 3-5 million years ago (unit). The populations of North America and Euraasia then started to diverge. The uplift of the Sierra Nevada and the onset of an ice age most likely caused the yellow-billed magpie lineage to split off shortly after. [9] However, a relatively small genetic difference indicates that some gene flow continued between the yellow-billed and black-billed magpies during interglacial periods up until the Pleistocene. [7].

Roosting edit

Magpies tend to roost communally in winter. Every evening, they soar, sometimes in large flocks and other times alone, to secure roosting places like thickets of trees or shrubs that obstruct the path of predators or, in higher latitudes, thick stands of conifers that provide good wind protection. [24] On colder days in Canada, they depart later in the morning from the roosting site after arriving earlier in the evening. [25] They typically occupy trees individually at the roosting site; they do not cluster. They sleep with their bill tucked under their back feathers and scapular (shoulder), going to bed earlier on chilly nights. [26] They might also regurgitate the undigested portions of what they ate during the day as pellets during the night. These pellets can be discovered on the ground and utilized to ascertain a portion of the bird’s diet. [27].

FAQ

How old is the oldest magpie?

Longevity: The oldest known wild magpie lived to be 11 years, 7 months old. They can live up to 14 years in human Care. Diet: Omnivorous; will eat insects, small rodents and some vegetation.

What is special about magpies?

The Eurasian magpie, for instance, is thought to rank among the world’s most intelligent creatures and is one of the few nonmammalian species able to recognize itself in a mirror test. Magpies have shown the ability to make and use tools, imitate human speech, grieve, play games, and work in teams.

How long do pet magpies live?

Mean life expectancy is 3.5 years for males and 2.0 years for females. In captivity these animals can possibly live up to 20 years [0445], though more detailed studies are warranted.

Do magpie birds mate for life?

During courtship they also use a tail-spreading display. Black-billed Magpies mate for life. The female initiates the pair bond by begging for food from the male, which begins courtship feeding. During breeding, the male stands guard near the female to reduce the chance she’ll mate with another male (which does occur).
