Millions of folk put out bird feeders of many kinds to attract as many possible species as possible over winter. The RSPB is still encouraging this actively and indeed carrying out another annual birdwatch at the end of January to see how many people can spot, so all the bird food (with RSPB subsidising costs of feed bought from their online shop to encourage more varieties to be sold) is being bought up by keen supporters of keeping fluffy birds well fed.
Has nobody actually thought about the potential impact of bringing loads of wild birds together to feeding stations where they normally wouldn't mix? Or are garden birds supposed to be completely immune to avian flu in which case why are we supposed to at all costs prevent one of them from pooping on our locked up chooks or stealing in to nick a bit of corn through the mesh and tarp constructions?
Government communication is incredibly poor but the messages are so contradictory that Joe Public is uninformed about the risks of bird flu at all AND being encouraged to bring as many wild birds together in one place as they can possibly manage. Those with poultry keeping neighbours are not making things any easier to live with, but you can't say a thing because their activities are completely legal, sanctioned and promoted all round..
I have badgered the RSPB to issue some prominent advice to the public about what people should do. Since about 50% of the adult population in the UK put up at least one bird feeder it is certainly one of the ways we could influence the spread of all avian disease. Unfortunately there are some in the RSPB who want to believe the spread of AI is entirely down to poultry movements.
To be fair to the RSPB they have standing advice to their members about disinfecting feeders regularly (mainly to prevent the spread of trichomonosis). While I think the RSPB could have done more to reiterate the importance of disinfecting feeders DEFRA and the BBC come in for the same criticism as, between them, they could have made sure everyone in the country knew about the disease while I'm still bumping into people who have no idea about it.
Personally I think having people stopping feeding the birds does the poultry keeper no favours. My experience of feeding the wild birds near the house and (with appropriate use of disinfectant on boots going in and out) stomping about the fields myself (a very unpleasant looking bird scarer I can assure you) I have remarkably little bird activity where I don't want it. Even the heron (who of course is not given to hanging from peanut feeders) has rather given up on visiting the pond. So my guess is that the little birds are less likely to break into your pens after food if someone down the lane is feeding them.
BTW - we disinfect the wild bird feeders and renew and acidify the water every day (though I doubt everyone is going to these lengths)
