A baby cardinal is ready to fly 10-11 days after hatching. 2-4 young are usually hatched at a time. When fully grown, their body length will reach about 21 cm.
At seven to eight weeks of age the young will take their first flight. They spend their days practicing flying and perching near the maleâs feeding perch calling when the male returns with food. Two weeks after fledging the young will start to follow the male on hunting trips.
