Birds generally make nest in a safer place. They are very alert about the safety of surroundings. When the work of nest is progressing, some of its enemies will observe it and watch the progress. The bird will smell it and abandon its nest before laying eggs.

they abandon their nest because they look for food to eat and they will be looking for grass to set up their nest on tree. they do not really abandon their nest unless a person is going to cut down the tree from below and the bird has to leave the nest there.
