Birds lore drop time I guess:

Pigeons are way smarter than people typically give them credit for but they are kinda dumb in weird ways. If you don't train them they will shit everywhere and they shed a lot of feathers and certain ones stick to everything and none of the parrot feathers seem to have that property. The runny poop is caused by some sort of microbe or something that she got treated for and then she drops nugs instead.

They don't seem to pay as much attention to their feet as parrots do. I had a box fan with the furnace filters on it in a cube shape blowing upward and she would just stand on it with the blades buzzing against her toenails so I switched to triangle layout blowing to the side.

Air filters are needed for any birds beyond maybe one budgie or finch but bigger or dustier birds justify one on their own. Pigeon is almost par with the notorious african grey in dustiness.

Pigeons are also super clingy and needy and always want to be with their favourite person at any expense. She will fly up and stomp by the door if I have to close the birds in their room. When she's out its constantly trying to preen my face and eyeballs unlike cockatiels and most other parrots that preen my hair. The eye poke isnt malicious but it's still awful.

Pigeons can also fully memorize the layout of a house and will establish a schedule. Mine would wake up and eat, fly around a bunch until I wake up, stick to me for as long as possible before and after work, fly all the way to the top floor toilet to poop, when my mom gets home she flies downstairs to get fed the same food but it tastes better from mom and all the birds agree, then flies back after eating and watching whatever garbage shows my parents like, then demands scritches for the remainer of the day.

I use a shop vac for the feathers and the poop during retraining for the new poop stations. I'm going to be trying out robo vac with mop if the other birds don't figure it out fairly soon. Hopefully they do because its been a lot of extra cleaning since I moved.

I've had as many as 9 birds at one time. Apart from my elderly cockatiel that came from an egg his parents secretly laid in my bookshelf decades ago, they are all shelter and rescue birds usually middle age or older. My daily schedule includes administering each of their medications which usually means blunt tipped syringe and like 0.3 to 0.8ml of up to 3 meds per bird, and recently even eyedrops for my cockatiel. A pigeon will be interfering the whole time guaranteed.
