Does it interact with other organisms?

The European turtle dove is suspected to be one of the principal introductory host of the West Nile virus into new regions of the world.  The West Nile virus originated in the West Nile region of Uganda.  From there it spread to Africa, the Middle East and southern temperate zones of Eurasia.  This spread of the disease was helped along by migratory birds like the turtle dove.  The reason why migratory birds, including the turtle dove are suspected to be the principal introductory hosts of the West Nile virus in these new regions is because in late summer to early fall, large amounts of migratory birds arrive in these regions.  The migratory birds bring with them large amounts of mosquitoes (a carrier for the disease plus many other human diseases).  Coincidentally, outbreaks of the disease have coincided with the arrival of these birds and the mosquitoes.  The European turtle dove is suspected to be a principal introductory host of the West Nile out of all of these birds specifically because the virus has been isolated from turtle doves that are actively migrating.
