Sick migrant birds stay and relax

Researchers at the University of Lund University have examined how many small birds work in the south due to winter winters.

After two studies on migratory birds in Scan Fleischerbooge, researchers have discovered that birds control their illness differently depending on their position and how strong their immune system is.

Researchers have vaccinated the birds to get the feeling of fever and cold.

"Birds that are sick but fly in Africa can not survive until they move southwestern Europe," says SVT Nahiter Scan, biologist and responsible researcher Ern Hagman.

Malaria-infected birds have also been investigated. At any place, birds continue their journey after a few days of rest before they completely reestablish.

Arne Hagmayne told SVT that "the next step in the research is to see what happens when they leave Flästerbara, if the sick birds come in winter or after waking up."
