Brown headed barbet nest building

Last month from my balcony, I had observed this brown headed barbet making its nest or home by creating a hollow within the tree. Birds mainly build nests for hatching of eggs and rasing the young but sometimes after making a nest, they simply abondon it. I find this surprising because I had observed the amount of hard work that is involved when creating a nest inside the tree. They are constantly at work everyday. Nests could be abandoned for two reasons. One is that the presence of a predator such a cat or it could have been a dummy nest.

I had also observed that when the male barbet wanted to rest, the task was taken over by the female barbet and vice versa. Both were taking equal responsibility in creating the nest. Here are some images I captured of the barbet making its nest.
