There is only one olive tree in the courtyard of the Dome of the Rock. The food source of the blackbird family who are living in this tree is the olives on the tree. One day, invading birds come from far away. They try to scare away the Blackbird family from the tree. Although invading birds repeatedly disturbing Blackbird’s nests, Blackbirds do not leave the tree and build nests over and over again. Invading birds collect all the olives from the tree and store them in their nests. Father blackbird buries an olive which he bought secretly under the tree, even though his family is about to die of starvation.
