Reverse migration, also called reverse misorientation, [1] is a phenomenon whereby a bird migrates in the opposite direction to that typical of its species during the spring or autumn. [ 1 ] For example, if a bird breeding in central Asia reverses its normal southeasterly migration, as shown by the orange arrow, it will end up in Western Europe ...
The appearance of migratory behaviour occurred in the tropics parallel with the range expansion of migratory species to temperate habitats. [11] Similar results of southern origin in other taxonomic groups can be found in the literature. [23] [24] [25] Distribution and biogeographic history highly determine the origin of migration in birds of prey.
In 2015 the anti-mass-immigration party, UKIP, proposed setting up a Migration Control Commission, tasked with bringing down net migration. [230] The vote for the UK to leave the EU was successful in Britain, with several commentators suggesting that populist concern over immigration from the EU was a major feature of the public debate.

The term ‘reverse brain drain' is closely tied with brain drain and brain gain because reverse brain drain is a migratory phenomenon that results due to the brain drain of the intellectual elites from developing countries and is the mirror image of the benefit of an inflow of high quality human resources which is brain gain.
Insect migration is the seasonal movement of insects, particularly those by species of dragonflies, beetles, butterflies and moths. The distance can vary with species and in most cases, these movements involve large numbers of individuals.
Officials say the loss and degradation of breeding, migratory and overwintering habitat; exposure to insecticides; and the effects of climate change have all contributed to the populations' decline.
Counterurbanization is the process by which people migrate from urban to rural communities, the opposite of urbanization. People have moved from urban to rural communities for various reasons, including job opportunities and simpler lifestyles. In recent years, due to technology, the urbanization process has been occurring in reverse.
Migration is the regular seasonal movement, often north and south, undertaken by many species of birds. Migration is marked by its annual seasonality and movement between breeding and non-breeding areas. [16] Nonmigratory bird movements include those made in response to environmental changes including in food availability, habitat, or weather.
