Will a mother bird look for her baby if the baby is lost?

Yes, a mother bird will typically search for her lost baby if she can locate it. Many species are instinctively driven to care for and protect their young, and the mother may call out or search the vicinity. However, if the baby is too far away or in a dangerous situation, she may not be able to find it. Ultimately, the behavior can vary depending on the species and the circumstances.
