Yes, I knew pigeons were stupid. I just didn't realize *how* stupid they actually were. On the fire escape stairs for my apartment there is a landing on every floor that is about 10' by 5'. The pigeons gathered a bunch of sticks and laid them all down on the concrete, but couldn't be bothered to craft them into anything resembling a nest.
Then they laid an egg on the landing.
No, not in a nest, but directly onto the concrete floor of the landing. It just has a handful of sticks scattered about.
I still don't see how they could have thought this was a good place to put a nest, since people are coming and going at all times of the day.
Pigeons are stupid.
