The other day I saw a hornero nest, broken, on the railing of a walkway through the dunes to the beach. You can see pieces on the ground. Probably broken by a human being of the juvenile variety, it begs a question: how could the hornero birds who built it think this was a good location?

Today I saw this: two hornero nests, side by side. Years ago I was told that horneros used to build their nests with the opening facing east for the morning sun, but with the increase in electromagnetic pollution, they had lost that sense of direction. I don’t know if it’s true, but the opening of the upper nest is pointing north.
