House sparrows are often considered a nuisance because they seem to be ever present everywhere. However, they are not found in the wilds away from human habitation. They have a preference to nesting in man made structures in cities and suburbs. These particular sparrows are nesting at my neighbors. The young sparrows appear to shiver and droop their wings like in the 4th image above when they anticipate being fed. I hope you enjoy and thanks for looking.
