Ammonia for Wildlife :/

This morning, I saw another bird having a drink in the container water
garden. I've decided to go ahead and monitor ammonia levels each
week. Being new at this, can anyone tell me at what levels ammonia
levels in pond water would be unfit for drinking by anything,
particularly birds?

Sure, birds probably drink from worse and may not drink it if they
know it's bad for them, but I would rather not contribute to their ill
health. Probably could just offer a bird bath with cleaner water. As
stated in a previous post, my ammonia levels seem to be hovering
somewhere in between 0 and .25 ppm, or at .25 ppm right now.
