Hornbills are large, colorful birds found mainly in tropical and subtropical regions of Africa and Asia. They are known for their distinctive curved bills, which can be quite large and often have a casque on top. These birds are primarily frugivorous, meaning they mainly eat fruits, but they also consume insects and small animals. Hornbills play a crucial role in their ecosystems as seed dispersers. They have a unique nesting behavior where the female seals herself inside a tree cavity, leaving only a small opening for the male to feed her and their chicks. This fascinating reproductive strategy helps protect the young from predators.
