North Asia or Northern Asia, also referred to as Siberia, is the northern region of Asia, which is defined in geographical terms and is coextensive with the Asian part of Russia, and consists of three Russian regions east of the Ural Mountains: Ural, Siberia, and the Russian Far East. North Asia is bordered by the Arctic Ocean to its north; by Eastern Europe to its west; by Central and East Asia to its south; and by the Pacific Ocean and North America to its east.

It is streaked greyish-brown above and on the breast and has a buff-white belly.
The greater short-toed lark is a small passerine bird. The current scientific name is from Ancient Greek. The genus name, Calandrella, is a diminutive of kalandros, the calandra lark, and brachydactila is from brakhus, "short", and daktulos, "toe".

The African paradise flycatcher is a medium-sized passerine bird. The two central tail feathers of the male are extended into streamers that commonly are more than twice as long as the body. The female tail feathers are of moderate length and without streamers. The upper parts of the male body, wings, and tail are boldly coloured in chestnut or rusty shades, but the underparts and the head are variably grey to blue-gray, with the head of the mature male being darker, commonly glossy black with greenish highlights. The beak and other bare areas, including a wattle ring round the eye, match the colour of the surrounding feathers. The female coloration is similar, though not so showy and glossy and with the head paler.
The KamchatkaPeninsula is a 1,250-kilometre-long (777 mi) peninsula in the Russian Far East, with an area of about 270,000 km2 (104,248 sq mi). The Pacific Ocean and the Sea of Okhotsk make up the peninsula's eastern and western coastlines, respectively. Immediately offshore along the Pacific coast of the peninsula runs the 10,500-metre-deep (34,449 ft) Kuril–Kamchatka Trench.

A flyway is a flight path used by large numbers of birds while migrating between their breeding grounds and their overwintering quarters. Flyways generally span continents and often pass over oceans. Although applying to any species of migrating bird, the concept was first conceived and applied to waterfowl and shore birds. The flyways can be thought of as wide arterial highways to which the migratory routes of different species are tributaries. An alternative definition is that a flyway is the entire range of a migratory bird, encompassing both its breeding and non-breeding grounds, and the resting and feeding locations it uses while migrating. There are four major north–south flyways in North America and six covering Eurasia, Africa, and Australasia.
