Like kids, you cannot keep some out of the water and others will not go near it. Some Amazon love water bowls, others misting spray and still others love to share a shower with us. What your Amazon will gravitate too is still to be found.
Leave the larger water bowl for your Amazon to consider, just may not be interested at this moment. The humid weather of summer will satisfy some Amazons others will splash extensively year around.
Misting bottle can cause problems, since it may look more like an attack than a bathing opportunity. Remember, the bottle's spray unit needs to be set to mist. A stream of water will work against you. However, having said that, someone will post that their Amazons love a stream of water. With the spray bottle set to mist, try mist up over your Amazon, not at them, so that the mist falls lightly from above your Amazon.
Like children, for most, bathing is an event that is found to be enjoyable.
Contact calls, contact calls, contact calls. You have just spent how much time getting your Amazon to enjoy being with you and now you leave the room. Surprise, your Amazon wants you to return and spend more time with him/her. And being fast learners, they figured out that lots of vocalizations will get back in the room. Quickly, this becomes a very fun game for the Amazon. When you leave the room, let your Amazon know - I'm going into X room and I'll be back. Then every so many minutes you call out your contact call. Big point is, do not run back into the room and do not keep a constant discussion going. Your contact call and your Amazon's contact call should be occasional status checks ( I'm OK are you OK?).
Every Amazon parent will develop their own contact call, which is specific to them as will every Amazon develop a contact call, which is specific to them. It can be a couple of words, a favorite section of song, etc... This is a very important parenting tool for that time your Amazon has gone 'Walk About' and you're looking for them. If you have developed a specific contact call, your Amazon will response with theirs and it makes it easier to find your Amazon under the table, etc...
