Red-Lored Amazon has big lump on chest
(Ormond Beach, Florida, USA)
My Red-Lored Amazon, aged 32 (I've had him since he was 6 months old), has a large lump on his lower chest/abdomen area which has formed over the last couple of months. It is hard and symetrical. It almost looks like the lower portion of his breast bone is suddenly very pronounced.
He seems fine and doesn't have any other issues. Any idea what this might be? Sorry, when I try to photograph him he gets happy and puffs up and the feathers mask the lump.
