Yes, caged birds are a sad thing. I'm also not fond of cleaning up their poop. ^^;;
It's nice to have them nearby though. Soothing somehow. I'd like to entice kookaburras over, but to do that I'd need to leave out fresh meat and fish... and that tends to draw the neighbourhood cats first... and also the crows and ravens. Wait, no, the ants would be there first.
