In order to transfer food to the male during breeding, the female Rufous-necked Hornbill seals herself within a tree cavity. She remains inside until the chicks are ready to fly

The huge, stunning Rufous-necked Hornbill (Aceros nipalensis) lives in Southeast Asian forests, including Bhutan, India, and Myanmar. This hornbill is distinguished by its brilliant rufous neck, huge yellowish bill, and distinctive black-and-white plumage. Males have red iris, while females have white. Rufous-necked Hornbills nest in large, mature trees in deep evergreen forests.

If fruit is sparse, these hornbills will eat small animals, insects, and reptiles as well as fruits, especially figs. Tropical woodlands benefit from their diet’s seed dissemination. Rufous-necked Hornbills’ powerful calls resonate through the forest canopy before they appear.

In Rufous-necked Hornbill breeding, the female seals herself within a tree cavity with mud, leaving only a small opening for the male to transmit food. Female stays in nest until babies are ready to fly. Unfortunately, habitat loss and hunting have made this species **Vulnerable** on the IUCN Red List, making conservation efforts crucial.
