Abstract : The migratory behaviour of birds has received much scientific interest, though many questions still remain unsolved. One of the reasons for this is the difficulty of following the birds as they move between breeding and wintering localities. Populations may mix on migration and the origin of individual birds is difficult to assess. READ MORE

Abstract : In Europe, tick-borne diseases are the most widespread and common vector-borne diseases and their geographical distribution is increasing. The dispersal of ticks depends on the movements of their vertebrate hosts. Avian hosts are more likely to be involved in long-distance range expansion of ticks due to their migration pattern.

There is a risk of novel subtypes originating from birds infecting humans, and the question of migratory birds as long-distance vectors for highly pathogenic avian influenza viruses has also been raised.
