I wonder why Linnies poops are more messy o-o... My parrotlet is relatively quiet, she does contact call often but she has a small voice so...eh. My grandma's cockatiel's calls are definitely louder. She is pretty messy though, she's less messy when I feed her fresh food on a plate though, outside her cage, so I do that.[/QUOTE
I've wondered this myself! From what I've read there just isn't enough research yet but it's truly amazing! And definitely has an odor.
