Some peoples are fully nomadic while others live in sheltered winter camps and lead their herds into the steppe in summer. Some nomads travel long distances, usually north in summer and south in winter. Near mountains, herds are led uphill in summer and downhill in winter (transhumance). Pastoralists often trade with or raid their agrarian ...
Map of early human migrations based on the Out of Africa theory; figures are in thousands of years ago (kya). [1]The peopling of the Americas began when Paleolithic hunter-gatherers (Paleo-Indians) entered North America from the North Asian Mammoth steppe via the Beringia land bridge, which had formed between northeastern Siberia and western Alaska due to the lowering of sea level during the ...
The English word nomad comes from the Middle French nomade, from Latin nomas ("wandering shepherd"), from Ancient Greek νομᾰ́ς (nomás, “roaming, wandering, esp. to find pasture”), which is derived from the Ancient Greek νομός (nomós, “pasture”).

The northern bald ibis once soared over North Africa, the Arabian Peninsula and much of Europe, including southern Germany's Bavaria. This bird species was extinct in Europe. Now it's back, and ...
A common pattern in North America is clockwise migration, where birds flying North tend to be further West, and flying South tend to shift Eastwards. Many, if not most, birds migrate in flocks. For larger birds, flying in flocks reduces the energy cost. Geese in a V formation may conserve 12–20% of the energy they would need to fly alone.
Many of these migrations are north-south, with species feeding and breeding in high northern latitudes in the summer and moving some hundreds of kilometres south for the winter. [18] Some species extend this strategy to migrate annually between the Northern and Southern Hemispheres.
