Passer domesticus
Damn invasive species -- coming here and eating our arachnids. As with all the other pictures on that particular branch, this was captured with a through-beam photocell trigger I built.

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.
ctsetan is right there is a very steep decline in the population of these especially in metro cities , we still have quite a few in the rural areas.
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.
Lucky you... here their population is dwindling.... and there have been many hypotheses for this reduction in their number. From cellphone use, to crows, to building of concrete houses etc. no so sure till now.
