The bird that woke us up has fallen silent. Can we bring back the Sparrow's chirp?

The house sparrow's chirp is now silent in many cities. BirdLife International reported a 64% population decrease in Europe since the 1970s. In India, Andhra Pradesh saw an 80% drop. Sujan Chatterjee said, "Modern architecture plays a decisive role here." Skyscrapers and lost nesting spaces pushed sparrows out.
