Far from being a dove, what you see is an aggressive pest that displaces other "kinder, gentler" passerine birds. Localized damage caused by sparrows can be considerable since they often feed in large numbers over a small area, similar to illegal aliens.  They interfere with the production of livestock, particularly poultry, by consuming and contaminating feed. Because they live in such close association with humans, they are a factor in the dissemination of diseases (chlamydiosis, coccidiosis, erysipeloid, Newcastle’s, parathypoid, pullorum, salmonellosis, transmissible gastroenteritis, tuberculosis, various encephalitis viruses, vibriosis, and yersinosis), internal parasites (acariasis, schistosomiasis, taeniasis, toxoplasmosis, and trichomoniasis), and household pests (bed bugs, carpet beetles, clothes moths, fleas, lice, mites, and ticks).  Yes, I dare say this was a symbolic visit, indeed!
