i had mentioned at the very beginning of the outbreak ,[when the public were frightened of their budgie etc and pigeons were not looked on kindly ] ,that the hawks which are protected could quite easy carry this disease???[killing these water birds that carry the disease, and capable of spreading it ] if Joe public thought this ,,,,it wouldn't be impossible to to kill two birds with one stone , so to speak ,,,,a great big if ,, but you get nowhere without trying.
