This is Philetairus Socius, the sociable weaver bird.

With the ingenuity of accomplished architects,
sociable weavers build huge cooperative apartment houses
- one straw at a time -
in the thorn trees and kokerbooms of Namibia.
Some of the larger nests are home to 300 birds!
Each chamber is about the size of a man's fist
and leads to the underside of the nest via a tube.
Amazingly this tube is lined with grass straws all pointing down and inwards.
This makes it almost impossible for snakes and other predators to enter.

You can find a great variety of nests in Namibia:

The artistic nest.

All in a row.


The Macabre.

The Rondavel.

On opposite sides of the street.

Here is the underside of this nest:

Because weavers eat mainly insects they do not need to drink water.
That is why you find them in some of the driest areas.
