I have just copied the following information from the BTO site if anyone finds dead or injured birds please phone for advice.
There is plenty of information available to be downloaded from both the BTO and RSPB websites.
If you observe dead birds or signs of disease in garden birds, please contact the Garden Bird Health initiative by telephoning the Institute of Zoology on 0207 449 6685. Reports help contribute to our understanding of the causes of diseases in birds using gardens
