Type species
Corvus canadensis [1]
Linnaeus, 1766

The genus Perisoreus is a very small genus of jays from the Boreal regions of North America and Eurasia from Scandinavia to the Asian seaboard. An isolated species also occurs in north-western Sichuan of China. They belong to the Passerine order of birds in the family Corvidae. Not closely related to other birds known as jays, they are instead related to the genus Cyanopica . [2]

Contents

The genus was introduced by the French zoologist Charles Lucien Bonaparte in 1831. [3] The type species was subsequently designated as the Canada jay. [4] The name of the genus may come from the Ancient Greek perisōreuō "to heap up" or "bury beneath". Alternatively it may be from the Latin peri- "very" or "exceedingly" and sorix, a bird of augury dedicated to Saturn. [5]

Species

The genus contains three species. [6]

Corvidae is a cosmopolitan family of oscine passerine birds that contains the crows, ravens, rooks, magpies, jackdaws, jays, treepies, choughs, and nutcrackers. In colloquial English, they are known as the crow family or corvids. Currently, 135 species are included in this family. The genus Corvus containing 47 species makes up over a third of the entire family. Corvids (ravens) are the largest passerines.

The Torresian crow, also called the Australian crow or Papuan crow, is a passerine bird in the crow family native to the north and west of Australia and nearby islands in Indonesia and Papua New Guinea. The species has a black plumage, beak and mouth with white irises. The base of the feathers on the head and neck are white. The Torresian crow is slightly larger with a more robust bill than the morphologically similar little crow.

<span class="mw-page-title-main">Eurasian jay</span> Species of bird

The Eurasian jay is a species of passerine bird in the crow family Corvidae. It has pinkish brown plumage with a black stripe on each side of a whitish throat, a bright blue panel on the upper wing and a black tail. The Eurasian jay is a woodland bird that occurs over a vast region from western Europe and north-west Africa to the Indian subcontinent and further to the eastern seaboard of Asia and down into south-east Asia. Across this vast range, several distinct racial forms have evolved which look different from each other, especially when comparing forms at the extremes of its range.

<i>Cyanopica</i> Genus of birds

Cyanopica is a genus of magpie in the family Corvidae. They belong to a common lineage with the genus Perisoreus. The generic name is derived from the Latin words cyanos, meaning "lapis lazuli", and pica, meaning "magpie".

<span class="mw-page-title-main">Jay</span> Bird of the crow family

A jay is a member of a number of species of medium-sized, usually colorful and noisy, passerine birds in the crow family, Corvidae. The evolutionary relationships between the jays and the magpies are rather complex. For example, the Eurasian magpie seems more closely related to the Eurasian jay than to the East Asian blue and green magpies, whereas the blue jay is not closely related to either. The Eurasian jay distributes oak acorns, contributing to the growth of oak woodlands over time.

<i>Cyanocorax</i> Genus of birds

Cyanocorax is a genus of New World jays, passerine birds in the family Corvidae. The generic name is derived from the Greek words κυανος (kuanos), meaning "dark blue," and κοραξ (korax), meaning "raven".

<span class="mw-page-title-main">Canada jay</span> Passerine bird of the family Corvidae

The Canada jay, also known as the gray jay, grey jay, camp robber, or whisky jack, is a passerine bird of the family Corvidae. It is found in boreal forests of North America north to the tree line, and in the Rocky Mountains subalpine zone south to New Mexico and Arizona. A fairly large songbird, the Canada jay has pale grey underparts, darker grey upperparts, and a grey-white head with a darker grey nape. It is one of three members of the genus Perisoreus, a genus more closely related to the magpie genus Cyanopica than to other birds known as jays. The Canada jay itself has nine recognized subspecies.

<span class="mw-page-title-main">Sri Lanka blue magpie</span> Species of bird

The Sri Lanka blue magpie or Ceylon magpie is a brightly coloured member of the family Corvidae, found exclusively in Sri Lanka. This species is adapted to hunting in the dense canopy, where it is highly active and nimble. Its flight is rather weak, though, and is rarely used to cover great distances. In spite of the Sri Lanka blue magpie's ability to adapt to the presence of humans, it is classified as vulnerable to extinction due to the fragmentation and destruction of its habitat of dense primary forest in the wet zone of southern Sri Lanka.

<span class="mw-page-title-main">Siberian jay</span> Species of bird

The Siberian jay is a small jay with a widespread distribution within the coniferous forests in North Eurasia. It has grey-brown plumage with a darker brown crown and a paler throat. It is rusty-red in a panel near the wing-bend, on the undertail coverts and on the sides of the tail. The sexes are similar. Although its habitat is being fragmented, it is a common bird with a very wide range so the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".

Brown doves are members of the genus Phapitreron in the pigeon family. Their common name refers to their overall brown coloration. They are endemic to the Philippines. All brown doves are tree-dwellers, but the different species occupy different types of wooded habitats; some are more restricted to old-growth forest while other make use of secondary forest and other woodland. Their main diet is fruit. They tend to be solitary in their habits and can be elusive. Some species in this genus have conspicuous black and white stripes on their faces and iridescent neck feathers. Males and females look alike.
