Having a nest of 3 mocking birds right outside my window at work, I watched as the mother bird feed the 3 little ones for two weeks. She worked through the day bring the babies different kinds of insects dropping the food into their mouths. She seem to know which one she feed last Even though they all would open those little mouths wide each time she returned with food. The father bird help feed and watch over them too. The male bird also sit on the eggs at times. The male birds tail was longer than the female's. The male bird also sit on the nest differently than the female did. I watched the nest being built the first week through the little ones leaving the nest at the end of 4 weeks.
