Nucifraga
The nutcrackers (''Nucifraga'') are a genus of three species of passerine bird, in the family Corvidae, related to the jays and crows. The genus ''Nucifraga'' was introduced by the French zoologist Mathurin Jacques Brisson in 1760 with the spotted nutcracker (''Nucifraga caryocatactes'') as the type species. The genus name is a New Latin translation of German ''Nussbrecher'', "nut-breaker". Extant species The genus contains three species: The most important food resources for these species are the seeds (pine nuts) of various pines (''Pinus'' sp.), principally the cold-climate (far northern or high altitude) species of white pine (''Pinus'' subgenus ''Strobus'') with large seeds: ''P. albicaulis, P. armandii, P. cembra, P. flexilis, P. koraiensis, P. parviflora, P. peuce, P. pumila, P. sibirica'' and ''P. wallichiana'', and also the pinyon and lacebark pines. In some regions, where none of these pines occur, the seeds of spruce (''Picea'' sp.) and hazelnuts (''Corylus'' s ...

Spotted Nutcracker
The spotted nutcracker, Eurasian nutcracker, or simply nutcracker (''Nucifraga caryocatactes'') is a passerine bird slightly larger than the Eurasian jay. It has a much larger bill and a slimmer looking head without any crest. The feathering over its body is predominantly chocolate brown with distinct white spots and streaks (absent from most of the body in southern Asian populations, which are sometimes treated as a separate species, southern nutcracker ''N. hemispila''). The wings and upper tail are virtually black with a greenish-blue gloss. The spotted nutcracker is one of three currently-recognized species of nutcracker. The Kashmir nutcracker (''Nucifraga multipunctata'') was formerly considered a subspecies of the spotted. The other member of the genus, Clark's nutcracker (''N. columbiana''), occurs in western North America. Taxonomy The nutcracker was one of the many species originally described by Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae'', ...

Clark's Nutcracker
Clark's nutcracker (''Nucifraga columbiana''), sometimes referred to as Clark's crow or woodpecker crow, is a passerine bird in the family Corvidae, native to the mountains of western North America. The nutcracker is an omnivore, but subsists mainly on pine nuts, burying seeds in the ground in the summer and then retrieving them in the winter by memory. Etymology and history The bird was described by the Lewis and Clark Expedition, with William Clark first observing it in 1805 along the banks of the Salmon River, a tributary of the Columbia River. Its scientific name literally means "nutcracker of the Columbia." Lewis recorded a more detailed description in 1806. A skin collected by the expedition was obtained by the ornithologist Alexander Wilson, who used it to produce an engraving for his monumental ''American Ornithology''. Taxonomy Originally placed in the genus ''Corvus'' by Lewis, Clark's nutcracker was later included in ''Nucifraga'' by Wilson, which also includes tw ...

Kashmir Nutcracker
The Kashmir nutcracker or large-spotted nutcracker (''Nucifraga multipunctata'') is a passerine bird related to the spotted nutcracker. Until recently, it was considered a subspecies. It is found in the western Himalayas. Taxonomy and systematics The Kashmir nutcracker is closely related to the Eurasian nutcracker (''N. caryocatactes'') and has only been split from it recently. Some authorities still treat these forms as conspecific. The two species are similar in appearance, though the Kashmir nutcracker in distinguished by a more whitish general appearance, along with a contrasting blackish crown, wing, and base of tail. It also has bold white spots on the base of its tail, with a relatively slimmer tail, and longer tail. It is monotypic. Description It is a distinctive corvid with heavily streaked and spotted plumage. They are usually in length. They have a wing length of , with a weight of for females and for males. It has a blackish crown and nape, with the sides ...

Corvidae
Corvidae is a cosmopolitan family of oscine passerine birds that contains the crows, ravens, rooks, jackdaws, jays, magpies, treepies, choughs, and nutcrackers. In colloquial English, they are known as the crow family or corvids. Currently, 133 species are included in this family. The genus ''Corvus'', including the crows, rooks, and ravens, makes up over a third of the entire family. Corvids (ravens) are the largest passerines. Corvids display remarkable intelligence for animals of their size, and are among the most intelligent birds thus far studied. Specifically, members of the family have demonstrated self-awareness in mirror tests (European magpies) and tool-making ability (e.g. crows and rooks), skills which until recently were thought to be possessed only by humans and a few other higher mammals. Their total brain-to-body mass ratio is equal to that of non-human great apes and cetaceans, and only slightly lower than that of humans.Birding in India and South AsiaCor ...

Lacebark Pine
''Pinus bungeana'' (English: Bunge's pine or lacebark pine or white-barked pine; Chinese: 白皮松 Japanese: シロマツ, ) is a pine tree native to northeastern and central China. It is a slow-growing tree In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are ... that can grow to heights of 15–25m and is frost hardy down to below -26 °C. Its smooth, grey-green bark gradually sheds in round scales to reveal patches of pale yellow, which turn olive-brown, red and purple on exposure to light. Distribution and habitat ''Pinus bungeana'' is native to mountains of China, but is widely cultivated as an ornamental, especially for its attractive metallic bark. It has naturalized in the Sierra de la Ventana of eastern Argentina. Uses It is grown as an ornamental tree in cl ...

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Pinyon Pine
The pinyon or piñon pine group grows in southwestern North America, especially in New Mexico, Arizona, and Utah. The trees yield edible nuts, which are a staple food of Native Americans, and widely eaten as a snack and as an ingredient in New Mexican cuisine. The name comes from the Spanish ''pino piñonero'', a name used for both the American varieties and the stone pine common in Spain, which also produces edible nuts typical of Mediterranean cuisine. Harvesting techniques of the prehistoric American Indians are still used today to collect the pinyon seeds for personal use or for commercialization. The pinyon nut or seed is high in fats and calories. Pinyon wood, especially when burned, has a distinctive fragrance, making it a common wood to burn in chimeneas. Pinyon pine trees are also known to influence the soil in which they grow by increasing concentrations of both macronutrients and micronutrients. Some of the species are known to hybridize, the most notable ones being ...

Spruce
A spruce is a tree of the genus ''Picea'' (), a genus of about 35 species of coniferous evergreen trees in the family Pinaceae, found in the northern temperate and boreal (taiga) regions of the Earth. ''Picea'' is the sole genus in the subfamily Piceoideae. Spruces are large trees, from about 20 to 60 m (about 60–200 ft) tall when mature, and have whorled branches and conical form. They can be distinguished from other members of the pine family by their needles (leaves), which are four-sided and attached singly to small persistent peg-like structures (pulvini or sterigmata) on the branches, and by their cones (without any protruding bracts), which hang downwards after they are pollinated. The needles are shed when 4–10 years old, leaving the branches rough with the retained pegs. In other similar genera, the branches are fairly smooth. Spruce are used as food plants by the larvae of some Lepidoptera (moth and butterfly) species, such as the eastern spruce budwo ...
