Sun conures do this at night because of natural roosting behavior. They sleep close together to: • feel safe (group protection instinct) • stay warm • maintain flock bonding In the wild, sun conures roost in tight clusters on high branches. Even in captivity, they still choose the highest, most secure spot and pack together before sleeping. This is normal and healthy behavior as long as: • no bird is being constantly pushed down • no fighting or distress sounds • the cage has good airflow Overal
