There is speculation today that the dead swan found in Scotland was probably a native of the area rather than a migratory bird from another part of Europe.

The swan is a mute swan which is native to the UK, though mute swans can also be migratory.

Of course if this was a bird from the UK, then it must have caught the virus from another source. Genetic tests on the H5N1 virus that killed it show that this is the same virus that is prevalent in other European countries, so it must have been carried to the UK from Europe by a migratory bird.

In the UK we must prepare ourselves for the inevitable news that H5N1 was responsible for at least some of the deaths of the other 14 birds that are currently being tested for bird flu. I understand that 12 of these are swans.
