Terrible start of my 2009- parrot lost

2009 started like this.. Watched fireworks on the nice roof of IFC. Pretty good start but then nothing's been better afterwards. Pissed off by various groups of folks in the morning and another in the afternoon.. not to be mentioned here.

About 3pm kinfolks came over my place for fun and watched some animals. Reptiles are my main dish but for them they like the warm-blooded more. One of the feature is my parrot in a 6-foot opened-cage and walking through the house on the horizontal ropes i put around. The parrot is a medium-sized one, and pretty owner-dependent. He likes to be hand-fed by me but for others who comes close a nasty bite is common. Anyways they were having fun with the parrot. then some of them came up to the roof and started to barbeque. After 30 mins or so when i was out the parrot flew through main door then up on the roof and gone........ everyone's speechless for a minute..

He didn't fly too much away but stayed in the treetop some 20 meters away from my roof. We called him and he responded...  I then came down to the root of the tree he stayed. Called him and showed him his favorite food, toy etc.. He was looked at us at all time and responded. I then climbed up in the highest point of the branches i could.. and kept doing.. He was only 20 feet away. He tried to come down but he didn't know how.. I understand that becoz he's a parrot not so good at climbing down. At home he used to like to stay on artificial branches more than real ones. After another 30 mins he's still there. Then I decided to get him fly over to other place. I used a long bamboo to put near to him then he flew to another tree near. That tree was even taller. and after some time we could still see him from our roof. He's staying there not moving for an hour or so.. until it's getting dark. He yelled more and I know he's nervous about the dark. We encouraged him and finally he flew over our direction, passed us, and then returned, and then landed on another tree like 10 meters away. After all efforts I couldn't think of any other way to get him back. I put the 6-foot cage and favorite food and toys up on the roof to let him see, and hopefully he will fly back some time. Next day morning, now, he is still there.. and calling a lot.. heartbeaten every time i hear the call.. For me if he is another bird i would be happy to see him live freely in the wild.. but i know he is not a wild-natured bird. From all behaviors I read he wants to come back but just doesn't know how. He is very timid to go to a new position, let a lone a brandnew environment. if he wants to go he would have been flying away.. And i can imagine how hard for him to get food and water, especially in this season..  Well, he's still calling in the tree next to here and i'm still looking at him.
