The common raven is one of the largest and most widely distributed songbirds in the world, found across the Northern Hemisphere from the Arctic tundra to deserts and mountains, easily distinguished from the smaller American crow by its larger size, heavier bill, shaggy throat feathers and deep, croaking call. It is remarkably intelligent, ranking among the smartest of all birds, and has been observed using tools, solving multi-step problems, and engaging in apparent play behavior such as sliding down snowbanks. Common ravens are opportunistic omnivores that will eat almost anything, from carrion and small animals to insects, grain and human food waste, and they are known to form long-term pair bonds and cooperate in complex social interactions, including apparent deception of rivals over food caches. The species has held deep symbolic and mythological significance across many cultures throughout history, from Norse mythology to Native American folklore.

In Ecosystem: Mojave Desert, Conservation and management
In the western Mojave Desert, human settlement and land development have led to an estimated 16-fold increase in the common raven population over 25 years.
In Biome: Desert, Distribution and habitat
They range throughout the Holarctic from Arctic and temperate habitats in North America and Eurasia to the deserts of North Africa, and to islands in the Pacific Ocean.

diet-classification (MediaWiki batch-API article extract states it plainly)Quote, diet-classification (MediaWiki batch-API article extract states it plainly)
Part of their success as a species is due to their omnivorous diet; they are extremely versatile and opportunistic in finding sources of nutrition, feeding on carrion, insects, cereal grains, berries, fruit, small animals, nesting birds, and food waste.

What is the common raven's true global population?
The Wikipedia article consulted for this species gives no single global population figure; secondary web results cite conflicting uncited totals (roughly 16 million versus 29 million) with no raw source page fetched to confirm either.
What would resolve this A dated global population estimate from a named, fetchable source (BirdLife International DataZone, Partners in Flight, or the IUCN Red List assessment page) with a verbatim figure this atlas can cite directly.
