Water — tap vs filtered vs bottled?

What water do you give your birds? I've been using Toronto tap water (which is generally good) but now I'm second-guessing myself. Is filtered necessary? Distilled? Spring water? Am I overthinking this?

I went through this exact thing with my Quaker parrot Pistachio! It lasted about two to three weeks and then resolved on its own. Hang in there.

I just snorted coffee out of my nose reading this. My Quaker parrot is looking at me like I've lost it.

When I had to travel, I used Bird Sitting Toronto and they were incredible with my Quaker parrot. Daily updates with photos and everything.
