On the anti-bird spikes. In the one small place I put them so that a nest wouldn't be right at my door and mama bird would try to attack my toddler. Seriously, no spikes a few feet away, you'll be fine. Nope. I know it's instinct or something to nest in a certain place each time, but come on.

On my runner rug on my balcony. Some pigeons found a couple twigs, laid them on the ground, then lay two eggs. Those chicks were born there and stayed until they were able to one day fly away.

A couple of seagulls made their nest in the cooling vent for the radiator of one of our backup generators. I caught it on our security cameras and mentioned it to management which resulted in folks being dispatched to evict them and clean up the giant pile of sticks and other junk they had dragged in.

Not sure what would have happened next time the thing started, so it was probably for the best. I still felt bad.

One of my coworkers left his car parked in his driveway for so long that a pigeon made a nest between the windshield and the windshield wiper, just right in that little space where it comes together with the hood.

Not peculiar but it was fun watching them failing to build their nest at the top of the tree in front of my balcony. The wind blew everything down immediately, it was like a slapstick film. They tried for a week but never managed to fix more than a few sticks and those are gone by now too. Hope they found a better spot.

In an empty wasps nest hanging from a house. I even saw momma bird come feed the kids. It was really cute.

Around here we seem to be lucky with our wasps. We get a new nest every year but they never bother anyone. One year they were in the ceiling right above the entrance of an old barn we use for storage. Was fascinating and eerie hearing them crawl around and work.

Where the gutter downspout meets the side of the house. Was worried for weeks until the babies started fluttering on their own.

On my balcony. We had enough problems with how unsanitary pigeon make their nest so we planned on not letting another one being build this year. We took out every pot, every object we had and break every morning the little stack of twigs they would make on the corner of the balcony only to waking one morning and to find out an egg was laid next to one single twig!!

Long time ago I saw a pigeon build a nest on a window sill, a place where there was nothing to anchor it to. They even laid two eggs before a storm hit and blew the whole thing away. :( Tho it was a pigeon nest and they are famously bad at building...

A narrow windowsill on my front porch.

Was kinda neat watching the little baby robins, though.

Got a Mallard that made hers right next to a rock in my back yard. Just on the ground.

At our old house, we had pigeons make a nest in a little space just under the roof, next my bedroom. Sometimes when I was trying to take a nap during the day I'd hear pigeons cooing and hear their chicks!

My school had a horn speaker thing and a bird made a nest on top of it. I remember the school stopped using that horn until the nest was empty.

Don’t know if it’s weird but I saw a cute pigeon trying to make a nest on the Metrolink Ticket Machines.

The thing is the machine is kinda not against a wall and a little slanted , so when I got to the platform there were twigs all over the floor and a poor nest on top. I tried to do a solid and put some twigs on the box to help.

We have a woodpecker that ia currently in the process of digging out a little cave in our neighbors wall.

I'm in Europe so this is a stone wall, maybe with some insulation. It sounds a lot like it's hammering stone though.
