That makes a certain amount of sense. I'm not too surprised seagulls would be ok in the presence of cats. They're large, fairly powerful birds. Crows also seem more common in SF than they were in previous decades, and again, I'd expect crows to be more resilient facing a predator like cats. They're large, highly intelligent, pretty tough, and fight in groups. Here's the thing - to a large extent, the birds you mentioned are urban birds, by and large. Seagulls are very coastal, but as you said, they eat trash, so the population will be very large in coastal urban areas. Crows also tend to flourish in urban areas. Pidgeons are notoriously urban creature, and while I've seen cats prey on them, they don't seem as vulnerable as smaller song bird species. I'm interested in whether these smaller songbird species are present in Rome or Istanbul or other places that are cat-heavy, though there are of course factors other than cats (some regions wouldn't have these species regardless of the presence of cats).
