Of course the bird will first shy away from this strange object and be too cautious to think of bathing. Put the bath house up every other day, perhaps with a small bunch of parsley in the water. Birds like parakeets that live in desertlike areas often take their morning bath in the dew-wet grass and don't necessarily need a real bath. If you observe your bird busily hacking to shreds a piece of carrot stuck between the bars without eating any of it, attach a section of washed and dried elderberry branch to the cage in such a way that the bird can gnaw on it. But always keep patient.
Parakeets are cautious and mistrustful of all innovations.
You may have to offer a number of delicious strawberries that will go untouched before your bird dares eat a seed off the fruit. And many a toy that later becomes the focus of passionate interest is initially regarded with suspicion and ignored until one day it is pecked at and used. Careful observers often notice how a parakeet will, after a quick shudder, shake out all its feathers and then calmly proceed to look over something new or put up with an overture at closeness. This shaking of the feathers indicates relaxation after agitation. A parakeet gets excited or agitated often for all kinds of reasons and to different degrees, but after shaking its feathers it becomes calm again, and it may often be ready for new ventures and discoveries.
