Explanation:

Stable 

Explanation: The House Sparrow has been found to be stable across the country as a whole, although declining in the major cities. It has been declared as the “State Bird of Delhi” to save the species and enhance awareness about their life and habitat. The reasons for the decline include decreasing insect populations (a key part of the diet of sparrow chicks) and paucity of suitable nesting sites. Moreover, the popular theory that radiation from mobile phone towers is a factor is not supported by the findings of this report.  Note: This question is scrapped by HPPSC.
