Secret World have confirmed that it is an outbreak of canker - lost wood pigeons, goldfinches and greenfinches

Now we have lost a Chaffinch - any ideas?

We have had 4 Juvenile Greenfinches die in our garden so far this year and a fifth now looking decidedly sick. Whatever it is appears to not be affecting other breeds of bird - young or old - so I think it is unlikely to be environmental i.e. from our feeders. Interested to know if anyone else is seeing this sad phenomenon?
