Great job!

Take notes for the final challenge: altricial animals mature after their birth, while precocial animals mature relatively at their birth.

Among birds, both altricial and precocial are born from eggs, but altricial birds (like songbirds, and parrots) are born immature and need greater parental care while precocial birds are born plumed, open-eyed, capable of movement and relatively autonomous (see ducklings.)
