I just got back from a visit with Ipo. She asked me to scratch her neck today and also talked up a storm in my direction whenever I tried to talk to her mom. All good signs. Tomorrow or Sunday they will come over here to visit and we will do a few visits this week before move in day on Thursday. I am also learning the hawiain words that Ipo knows so that I understand what she means as well as me being able to use the words she knows. For example, Good bird is Good wahini for Ipo. Another one is that she seems to have a sense of time and her word for a quick visit or someone being gone quick is wiki wiki (I think - I better check).
I am going to have a list of the words she knows that mean specific things - fritos for favorite food, etc so I will have a clue and her mom will come over each day the first week to make sure Ipo and I are both settling in well and make sure I am not missing something. I think I was told Ipo says over 100 things regularly but at least quite a few are in English (gonna take a shower, gonna brush your teeth, see ya later, tear it up, names of people and the other animals in her current home, etc) She also understands a lot of words as well (gentle, etc). She clearly is interacting with language more than just repeating and I look forward to that.
By the way, her owner has been reading the forums a bit and I believe she really appreciates hearing from you all that it isn't wrong to feel so sad about rehoming a bird as well as that the way she is going about it is ideal. It isn't a fun thing to have to do.
