Notice the dried grasses and pine needles nest.

 The bluebird chicks are altricial. This means they cannot move around on their own upon hatching. They have only a few feathers. They stay in the nest and the parent(s) feed them. Both parents care for their young. The bluebird chicks leave the nest in about 15-18 days.
