I agree COMPLETELY, a lot of damage came after some naive perception of pepole abaout nature....We have a few invasive bird species. Actually there are almost 100 nonnative bird species in the US. Also, I'm sad to say, lots of invasive fish and reptile and mammal species. And don't get me started on invasive plants. Half of my time gardening
There are 7 of our most common non-native bird species. I think they differentiate non-native and invasive. Invasive are those that have a negative impact on other species or the environment in general.
Some moron who was enamored with Shakespeare decided that it would be a good idea to introduce to North America, all the species of birds mentioned in Shakespeare's works. Those included European Starlings and House Sparrows. Starlings do $800 million in crop damage every year. House sparrows (AKA English Sparrow) are one of the most common birds in the US driving native birds from nesting places.
I have a friend who is a primate expert who used to work at the St. Louis Zoo and every time she learns of some people bringing in nonnative species, she declares, "people are scum". I concur.
I distinguish between Introduced to invasive species. We have here a crow species the Indian crow Corvus splendens
that is Naturally expanding his living range and came Israel from India-Irak-jordan.
in this case I don't have any problem, because it is a natural process.
Corvus splendens
