Bird Nest at my Balcony

Look at this - it looks like just another plant which has overgrown at my balcony, right?



















Then hub pulled me to see the outside - ohmigosh...a bird best?? Hub has been insisting that there was a bird nest because we have been hearing a lot of birds chattering away but I insisted - no way. On closer look, the nest looks empty. I cant go anywhere nearer to take a better pict as the nest is actually facing outwards.











Why I am astounded by the bird nest on our puny tree because there are many more trees down there.
