Wow...just wow.
It boggles my mind that anyone could think that any living being in such a powerless situation could be fine totally alone for 9 days straight.
While your last post did say the parrot was going to come with you, did your boyfriend not have any relatives or friends that could have come over to at least change the water/food? You don't always need to pay a birdsitter (some people are just happy to help out), there is really no excuse for this to have even crossed his mind...
