Just ran across this thread and am new here and mainly just read.
I'm so so happy for you and getting your bird back!!!
Brought tears to my eyes also, as I have an umbrella cockatoo and about 10 years ago he got out and ended up flying about 25 to 30 feet up in a pine tree. I spent all afternoon outside in the yard calling him and had his cage outside with the door open for him but no luck. It was starting to get dark out so I felt I had no choice left but to climb that tree. I begin climbing also figuring it would be the last time I'd see him, figuring when I got close he would take off again. So I mentally braced myself for a final good bye as I climbed higher. I finally made it to him and stuck my hand out and he climbed on my hand like it was nothing. Now I had a new thought come across my mind.... How the heck am I gonna get down??... Well believe it or not I was able to make it down with just one hand, there was no way I was going to let go of him so one hand it was. It was a happy tearful end!!
Again I am so happy that you had the same tearful happy end to your stressful ordeal!!!! Thank God!!
