In a remarkable display of devotion, a hornbill couple from Planet Earth III have transformed their tree hole into an impregnable fortress to protect their nest. Nesting can be perilous for birds, so the female hornbill goes to extraordinary lengths to safeguard her eggs.

Once settled inside the tree trunk, she pulls out her flight feathers, preparing for an extended stay. Her partner helps by bringing a beak full of mud, which she uses to seal herself inside. This fortress not only keeps predators at bay but also traps her in, turning the nest into a cozy, albeit confined, home.

For the next two months, the male hornbill is a dedicated provider, delivering food directly to her “door.” Though it might seem like he’s doing all the work, the female is busy too, using the sustenance to lay and incubate two precious eggs.

After six weeks, the young will be ready to fledge, and the family will break free from their temporary confinement. Until then, this devoted couple remains hard at work, showcasing an extraordinary level of commitment and teamwork.
