The Times reports the cheering chirruping of house sparrows, once common in gardens, has declined drastically over the past four decades. A generation after numbers plummeted, however, there is hope.
At the 41st annual birdwatching weekend held in January an average of 4.7 house sparrows were seen, prompting hopes that they have turned the corner. Almost 1.3 million house sparrows were seen over the weekend. Experts believe the mild winter may have helped smaller birds, which are susceptible to cold conditions.
