LP’s (the informant) family is originally from Mexico. Apparently her entire family believes in the following idea about black crows being a bad omen, but her mother is especially superstitious about it. She’s the only one who actually goes outside to scare them away whenever she sees them. This is a superstition regarding bad luck that can come from crows around your house specifically.
“Whenever you see a black crow coming towards your house it will bring you bad luck. So my mom goes outside and will yell at the crows in Spanish and get them to go away. She scares them off because they will bring bad luck if they stay. If they actually get in your house…well…you’re done for. But if they’re in the street, you have to be respectful because it’s not your property, so you don’t scare them off. According to my mom, she was seeing a lot of crows around my house before the fire (a portion of her house caught fire about two months ago) but she was too lazy to scare all them off. So she was convinced that since she didn’t make them go away, my house was cursed and that’s why it caught fire that one day.”
I have heard about similar superstitions with crows, but more so black cats. I know birds can always represent different types of omens, and ravens are especially symbolic of death and other negative connotations. I think it’s interesting how her mom truly believed that the fire in their house, which was actually due to a power surge, was a result of not scaring away these crows.
