Bird Trapped

We found this little bird screeching in the tree today. Firstly its little foot was caught up in some yard so I phone Riaan and he said he'd try and free him when he got home from work. I see now that his wing is also caught up in this yarn.

I hope he's going to be okay and that we'll get to free the birdie...he looks so scared.

Any ideas of what kind of bird it is?
