Australian Raven discolouration

["Roger Giller" <>]

Hello all,

Yesterday I and several friends observed an Australian Raven with a quite 
noticeable greyish coloured breast. I did not get the bino's on to it but did 
manage a couple of rather ordinary photos. One of these shows signs of a 
pinkish colouration suggestive of bare skin, but we did not notice this at the 
time. The bird was seen several times over a 5 hour period, and did not appear 
to behave in any unusual way.

Any suggestions as to a probable cause for this discoloration, and how common 
is it? I have never seen it before.

Location was Burnham Burnham Reserve, Woronora River, Sydney.
