Problem: The migration of birds also aids the movement of other species, including those of ectoparasites such as ticks and lice, which in turn may carry micro-organisms including those of concern to human health. Due to the global spread of avian influenza, bird migration has been studied as a possible mechanism of disease transmission, but it has been found not to present a special risk; import of pet and domestic birds is a greater threat. Some viruses that are maintained in birds without lethal effects, such as the West Nile Virus may however be spread by migrating birds. Birds may also have a role in the dispersal of propagules of plants and plankton.
What has been studied as a mechanism of disease transmission?
The answer is the following: bird migration

Problem: The island was administered as an extension of Virginia by the Company until 1614. Its spin-off, the Somers Isles Company, took over in 1615 and managed the colony until 1684. At that time, the company's charter was revoked, and the English Crown took over administration. The islands became a British colony following the 1707 unification of the parliaments of Scotland and England, which created the Kingdom of Great Britain. After 1949, when Newfoundland became part of Canada, Bermuda was automatically ranked as the oldest remaining British Overseas Territory. Since the return of Hong Kong to China in 1997, it is the most populous Territory. Its first capital, St. George's, was established in 1612 and is the oldest continuously inhabited English town in the New World.
In what year did the islands become a British colony?
The answer is the following: 1707
