House sparrow

That is a shame but is the nature of weeds .. they do far better when displaced than in their natural environments where all the competitors, parasites, diseases etc. have evolved along with them. I remember visiting a zoo in England maybe 20 years ago where the first display as you entered was a racoon. There it was this neat, cute, interesting animal from the Americas. I had to joke that they had put it in a woodland setting rather than a back alley foraging through the garbage.

The problem is that they are an invasive species here where they outcompete some native species for nesting sites etc. So someone might well post on one of my other sparrow spottings that I'm lucky to have seen them due to dwindling numbers ... and list these guys among the theorized causes.
