So, Paco has a very pronounced preen gland, which I read is common for moluccans. Phoenix and Paco's look similar, with one big tuft of what looks similar to a down feather coming out of the middle of it. Picaso though, has two little, separate tufts of feathers. One coming out of each side of the gland. Is this normal, for them to look different like that? I tried to get a picture, but my camera is not good enough to see the detail. Thanks!
