Altricial versus Precocial
Looking for a meal:
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.
Precocial chicks are capable of moving almost right away. They leave the nest quickly after hatching. They are covered with a fluffy down. Bobwhite Quail chicks and wood duck ducklings are examples of birds that leave the nest soon after birth.

Make a prediction. If you hear peeping, what do you think you will see?
Based on what you have learned about altricial and precocial, this chick is:
4. A teacher tells your mom you are precocious. What does that mean?
