At a beach entrance in Marindia, you can find one of the ubiquitous mud Hornero nests. Hornero means baker, and they are so named because their nests look like traditional mud ovens.

You know, like this. (Photo source)

But if some humans want to help and provide a ready-made solar-panel roof, well, so much the better.

The entrance to the nest faces the beach (ESE). I was told once that the birds build their nests with the opening facing east for the morning sun, but I have seen them facing several directions. The same person told me that was because they have become disoriented since the advent of cell towers.
