They’re perfectly nice birds unless you’re a farmer, leave out trash, or conveniently have an open dryer vent for them to loudly nest in like I do.
For those that don’t know, they’re a common nuisance bird because they nest in enclosed cavities like tree trucks or the siding of your house or any open vents. If you’re from the US (At least the Midwest or East Coast, not sure about the western states) and have seen very large flocks of small black birds dancing in the air like schooling fish, behavior called murmations, those are Starlings.
They’re pretty loud in general so you would probably know, but they don’t tend be like to hang about indoors. Might just be house sparrows if you’re hearing them on the warehouse floor.
You should download the Merlin ornithology app. It’s built by the Cornell ornithology lab and has picture and sound ID features for birds as well as just a lot of generally useful identification information.
