Yesterday I was reading some articles about common birds deseases, etc. and the thing that got my attention was something about black/brown discoloration on green feathers when the bird has a liver desease. On the other hand, I've heard that black tipped green feathers are pretty common on GCC (Louis has some dark tipped feathers on the back). My wondering is, how to tell if feathers are starting to get discoloured abnormal?
