Do Canadian geese mourn their dead goslings?

Yes, Canadian geese have been observed displaying behaviors that suggest they mourn their dead goslings. When a gosling dies, the parents may exhibit signs of distress, such as calling and staying close to the deceased chick. They may also show reluctance to leave the area where the gosling died, indicating a form of attachment and recognition of loss. While research on this behavior is limited, these observations suggest that they experience a form of mourning.
