Babs can migrate hundreds of kilometers using warm air flows.
This conclusion was reached by the International Group of Researchers of the Institute of Evolutionary Biology of the Max Planck Society (German. Max-Planck-in -intitt Für Evolutionsbiologie)-a scientific institution in the European Union.
To study the features of migration, the researchers equipped 71 voles of the species ordinary evening evening with ultra -light sensors, which recorded their activity in the four -week spring period.
Contrary to the expectations of researchers, bats do not follow a single migration corridor. Scientists have found that bats are able to overcome up to 400 km in one night – this is a flight range for these animals. In addition, on the migration route, these animals stop on vacation.
Researchers noted that the movements of bats on certain days increase and it depends on the weather.
Babs are chosen for the flight of night with warm fair winds that bring storm fronts. Such a strategy allows them to save energy during long -term migrations.
“The data of the sensors are simply amazing! We do not just see the path of bats, but also understand what they experienced during migration. This gives an idea of the most important” decisions “that animals made during their energy-consuming and dangerous trips,”- said Edward Herm, co -author of the study
According to scientists, bats overcome about 1,600 kilometers during spring migration, but it is necessary to conduct additional research to determine the behavior of these animals during the year. b
“We are still far from observing the full annual cycle of migration of bats over long distances. This behavior is still a black box, but at least we have a tool that sheds light on it,” said Hermm .
The results of the study are published in the journal Science (“Science”).
