The dishes that came with the cages can't be used for drinking water. My birds would use them as bird baths. For my lovebirds, parakeets, and finches, I get the tube water feeders. Daily I check the water and make sure enough is in there so they have a good supply to drink. I even have a brush, etc to clean it out. When I travel, I get the large ones that I can put in their cages so they have a large supply of water they can drink, not use has a bathroom or bathtub.
Each cage has a tube feeder in it for the birds. The kind for water.
