"I do not know if it is just parakeets but I am owned by 8 of the little weirdo's and the only time they use this bath is as a drinking dish. They will stand on the opening of the bath, put one foot on the side bars of the open cage door and reach as far as they can in and drink. And then go not a foot further and bathe in their actual water dish.
Mine came with no clips so we had to wire it into the cage, which of course makes for interesting cleaning. We have three cages attached together to make one large maze of cages, the center one being the flight cage and we had to snip one of the cage bars just to fit this into the door opening.
I would not recommend this unless one, you have measured the doors on your cage and two, you actually believe/know your birds will use it. Or else you will turn out like me, putting their vitamins in the bath water and watching them attempt to bathe in the water cups."
