The hornbill installs his wife inside a tree
trunk and seals her up for three months.
:48:05
But first he cleans out her cell
to make sure she'll be comfortable in there.
:48:11
Then he flies off to get some clay
to wall her in, and she starts undressing.
:48:16
She plucks out her coarser feathers so she
can be soft for the chicks when they hatch.
:48:22
Without those feathers, she can't fly,
but she won't be using her wings for a while.
:48:28
He comes back with a beakful
of clay and blocks the entrance...
:48:33
...so she and her chicks will be safe.
:48:37
He leaves only a slit, the
size and shape for a hornbill's bill...
:48:41
...so he can bring her food and water
while she lays and hatches her eggs.
:48:47
And then there are suddenly five mouths to
feed, and Father has to provide for them all.
:48:53
Throughout the summer,
he's the hardest-working member...
:48:57
...of the opulent Cubango community.
:49:10
When the chicks grow bigger
he has to provide a balanced diet.
:49:15
One day, green stuff with lots of vitamins.
The next day, proteins.
:49:24
One lucky day, a swarm of proteins
comes buzzing around the nest...
:49:29
...saving Dad a lot of labor.
:49:33
He's quite sorry when they leave.
:49:36
Oh, well, back to the grind.
:49:39
The chicks have been taught not to pollute
their own nest, and their aim is remarkable.
:49:49
As they grow,
it gets crowded in the nursery.
:49:52
So one fine day, Mother breaks
open the roof, and out they come.
