My cockatiels don't like bathing. So I mist them regularly which is easily done in their cage outside in the Summer, but when it's cold, I do it in the house, which means that everything around the cage, especially the window, gets soaking wet!
Mango, the GCC, loves to bath in the sink. She will ask for it by moving down on my arm when I am cleaning up after preparing their food. She loves to move around in the sink while it is filling up under a light spinkle. Once she's had enough she lets me know and crawls right back on my hand and shakes, and shakes, until I cannot see through my glasses LOL.
