The faint sounds of baby birds squeaking from within their nests inside the courtyard walls of the Bon Aire Apartments building in San Francisco's Civic Center.
The building managers continue to send workers to attempt to drive the nesting birds out of their nests and seal the courtyard with netting which is full of holes. All eight attempts since March, 2016, have failed.
Whole families of birds are repeatedly endangered here and need help.
