Until now, the possibility of finding work was one of the main reasons why foreigners chose our country. It also happened in the case of Spaniards in transfers between provinces. However, since the crisis we move for other factors such as quality of life or weather conditions, according to a new study. In addition, the reasons vary between foreigners and natives.
Spanish researchers have developed a system that tracks human displacement caused by climate change using the tracks of mobile phones.

Its blue and brown-coloured plumage is undoubtedly the most distinctive feature of the European roller, a threatened migratory bird. Up until now, little was known about this bird's migration patterns and wintering. For the first time, scientists from nine countries reveal the routes between the southern part of Africa and Europe taken by a considerable part of this species which is currently in a fragile state of conservation. Researchers have been able to uncover this information with the help of geolocators and satellite transmissions.
