- Catbirds can recognise their own eggs and remove any laid by imposters
- Besides their usual diet of berries and insects, they will eat odd things from feeders such as cheese, crackers and milk
- The phrase 'sitting in the catbird seat' means being in an enviable, winning position. During breeding season, catbirds compete with others of their species by singing from higher and higher perches. The bird that reaches the highest perch wins the territory.
