Sparrows my man. You don't know, none of you anons know.
Sparrows will fit through any gap that a 40 x 40 mm fan will fit in. They pitch their territory wherever the sun first lands at dawn. Their chirping sounds like an ungreased wheel bearing. It's loud enough to echo off of buildings. In the evening they stop, when the sun's behind objects or leaving the horizon. They run a protection racket and kill other small birds. Not for sustenance, but as competition and for sport. This protection racket extends to locusts and reduces the volume of swarms, but you have to live in God's angry dump pile of a country for this to be relevant. Everywhere else, especially in the United States where you already had birds that did the same job, these birds come along and eat half the corn or seed you lay down. Jewish synagogues used to not destroy them, because they were stupid (and also deserving of plague nobody likes the Pharisees). Hence Jesus' exceptional claim that God cares about the five birds you can buy for a penny. He never explained out why they exist. I feel like they are as tapeworms, to punish you from living in a filthy uncaring place and render evident your folly.
In any case, unless you live in hot or bugmen territory worthy of a plague, then all sparrows do is make sure you don't have more grain in the silos. No sparrow has ever decided not to be an asshole. No sparrow has ever ignored you benignly or offered you a friendly greeting, unless you feed them and don't mind that they are equipped without any sphincter controls.
They are as redeemable as a bullet in the head, and if you want a creature worse than a rat then go out and find a sparrow.
