Sometimes moving things around isn't quite that simple and can get quite complex...unless of course they are placing them in zoos under some protection breeding program. When it comes to wildlife species one usually depends a multitude of others to make the whole ecosystem work, take out one then another gets unbalanced, obviously the tribal members don't understand those processes and may one day find killing off the bird for it's feathers had detrimental effect(s) on their environment. Same thing could result by adding them into a new environment, it could throw that environment off as chances are whatever functions the bird serves to it's environment there is a high probability that there is already one function in the same manner as the new environment they want to introduce it to.

I must admit I've seen quite a number of stories of cats being rescued by fire departments out of a host of trees, even a black bear cub, but haven't ever seen a dog rescue from a tree. I think it was either last summer or the summer before that a black bear cub somehow managed his way into our city, it was actually only a few short blocks from here that someone called and reported a bear in a tree outside their house. The dispatcher probably thought the person was drunk as that's never been heard of around here. When the news did the story they made mention of people having seen the bear but that was the first time they caught up to him. That one ended up being a bit much for the fire department to want to handle so they called in a wildlife experts. The only way to get him out of the tree was to tranquilize him and hope he didn't hurt himself to bad from the fall, which he did end up being fine. The DNR scooped him up and took him back north into the woods where he belonged.
