What is wrong with this Kereru?

[Jan]

I've been sent this pic of a Kereru with what looks like a nasty case of prolapse. Does anyone know what it is and how it's caused and whether it should recover naturally? Pic from Port Levy, Banks Peninsula.

Hi Jan.
I am unable to actually see the photos as they just come up as three little red icons.

Sorry, I can't seem to attach a pic, but Neil has offered to attach them for me. He perhaps hasn't seen my msg yet. Brett Gartrell says it isn't a prolapse but a swollen mass around the vent. More info later.

If anyone is keen to see the pics do send me a PM with your email and I'll send you them. Thx, Jan

Sorry Jan, I got flooded with work last week. Photos are there now.
