Baby birdies in the Bamboo.

Martin and the boys were trimming our bambo plants this evening as they had grown rather large ..
During the spot of pruning Justin spotted a birds nest complete with baby birdies still inside ..
So I took a quick pic and if you look carefully you can see the beaks and eyes of 2 birdies ,I hope they are ok as one tried to have a go at flying out of the nest and failed .
I am not sure what type they are either -any suggestions gladly received .
