In the warm tree hole, there were over a dozen dark green eggs that were the size of an adult's fist. The entrance of the tree hole was sealed with a thin layer of mud; the mud was also mixed with some hay.
Coo. Coo. From outside the tree hole, one could hear the unique call of the egg-thief bird, similar to the cooing of a widow that lived next door.
After ensuring there was no response to its call, the egg-thief bird was happy. It carefully reached its claws out toward the dry mud on the tree hole and gently started scraping. Soon, it had scraped a big hole in the front of the tree hole.
It sneakily peered through the big hole into the tree. Its eyes shone when it saw the eggs.
Coo. Coo. Coo⦠The exuberant call of the egg-thief bird could be heard from the rest of the woods.
Struggling into the tree hole, the sharp beak pecked an eggshell, and the thick yellow yolk flowed out.
