Until people start getting sick there is no reason to worry and that's not likely to happen unless someone is living with poultry the way some people do in parts of Asia. Even then there probably isn't much to worry about. If H5N1 eventually does jump to humans, and that's still a big if, you'll more than likely catch it from one of your mates than any bird. I'll avoid the obvious catching diseases from "birds" joke here :-)
So there is no risk, unless of course you own a cat. Apparently they are susceptible to catching it.
Scientists know so little about H5N1 in cats that it is difficult to assess the risk they pose when infected, the virologist Albert Osterhaus from the Erasmus medical centre in Rotterdam and Peter Roeder, from the UN food and agriculture organisation, wrote in tomorrow's issue of Nature.
So if your cat brings you home a dead bird and puts in on the door step best not to leave it there. I knew there was a reason I didn't like cats.
Update 6 April: Bird Flu may be in Northern Ireland.
Update 7 April: Looks like the birds in Northern Ireland got the all clear. They are still dead, of course, but they can be happy in the knowledge that they didnt die of Bird Flu.
