We have a Magpie in our street which has a huge and grotesque growth on the
carpel joint of its left wing. It is approximately the same size and shape
as a champagne cork, but doesn't seem to prevent it from flying (it is
pointing forwards along the bird's body), and that pair have just raised two
chicks. Is this likely to be due to Avian Pox?
I have heard from an American ornithologist that about 20% of US birds he
handles have some sort of swellings or growths from Avian Pox. I wonder what
is the figure in Australian birds, do we have th edisease here? If we do I'd
say it I would say lower, but it is more difficult to see odd growths on
birds unless you do handle them, so I would like to be dogmatic on the
point.
