Well, until today it was only three. Which is still a lot of birds, but it doesn't sound as crazy-person as five birds does. Still, once you have a bird, another bird isn't that much work. And while I'll concede that five birds are certainly more work than one, they aren't noticeably more trouble than having just three. I think we're at max bird capacity now, though. Unless the vet talks us into some other strays...

I love the image of the tunneling bird with his little secret cave! But our birds like caves and tight spaces, too, though they've never built their own. Huevo loves to be squashed and to wriggle around under and through hands, as does Kazoo (which is why the way I'm holding him in the photo is actually not cruel, although it may look to be so). Garuda likes squashing, too, but not quite so much as the other two. I get the impression that lots of birds would happily dig tunnels or crawl under things if given the chance.
