You guys need not worry about leaving a bird when going out or going to work. They actually cope better than what we do. I too was so worried, when I began working in May this year. Mishka and I were together every single minute of every single day, for 3 years and 6 months. We spoke 24/7, played and trained each night.
Since working I get up each morning at 4.30am, and Mishka is awake from about 5.30am. We spend quality time together, he has a shower, gets blow dried, and fed his formula. I then sit talking with him till 8.20am, asking him questions and visa versa.
I do leave cd's playing for Mishka, all saying he has learnt, sentences , practically everything he has ever learnt. I still continue to change and rotate his toys each and every week, knowing how important it is to keep him stimulated and entertained. I am fortunate Steven my youngest son, is home often (his in Uni) and changes the cd's for Mishka very often.
If anything Mishka is more loving and playful. The minute I walk in the door, it's hi mom, mommy I love you, he chats continuously for about 1 hour. When I am busy doing the washing, he walks into the kitchen, sits and watches the washing machines turning his head and whistling. He follows me everywhere I go. He has the same amount of playtime on his playpen each evening, then an hour on my lap. He is learning new words, and making them into sentences even quicker than before.
I only have one day off a week, cleaning etc, but make sure Mishka gets my full attention, and we chat all day.
PS when leaving today I stood outside the apartment, watching what he would do. Mishka began to shout out mommy, hey mommy I almost began to cry. After a few minutes he began talking away and playing. They are so much like our human kids, except for their poppies, birds ones do no stink LoL
