The document discusses a hornero nest that was built on a window of the author's building in Uruguay. The author took over 600 photos of the nest over the 2 month period it was being built. They share the photos online for others interested in the environment and wildlife. The horneros worked 8-10 hours a day constructing the nest, except for Sundays when they did not work.

41. Urban Horneros
In Uruguay we used to see Horneros’ nests everywhere, this peculiarity nest was built on a window
in the building where I live. Having the nest "there" I accumulated over 600 photos.
It all started for curiosity and I was fortunate to witness it every day. After seeing the photos my
family and friends were very surprised.
I thought it would be good to put the photos online to share with you, mainly those of you who
care about the environment, so here they are, I hope you like it.
I am not a photographer. The nest was built between late September and 30 November. They work
from 8 to 10 hours a day but they didn’t work Sundays!
