So how exactly does this work?
Just like mice and bugs, wild birds live prolifically alongside humans in very "unnatural" ecosystems. The thing is that in these locations you don't really have all the natural predators that would be there in nature to keep the bird population in check, so does this mean that with birds pretty much having free rein over these areas with so much abundance and little to no threats that they are in a constant state of mass starvation due to having the freedom to overbreed? Or am I missing something on what's keeping these bird populations contained? It's pretty weird to think about when we tend to think of these critters leading a pretty chill life harmoniously just singing and flying around. How do you even begin to understand these broken systems that are so far removed from the way the species evolved? Do they even have any important ecological value or would they be better off gone in the way we also think of rodents in urban areas as pests?
