Green capital to become haven for migratory birds DC urged the people to cooperate with the government in making the federal capital green ISLAMABAD: It is said that birds are immigrants without borders and with changing seasons, they change their habitats. The migratory birds from China descend on Islamabad, Rawalpindi, Azad Kashmir, and northern areas in November as the weather back home turns cold. They lay eggs and stay in Pakistan until the hatchlings and nestlings grow up after which the winged migrants return to their homeland. For the protection of wildlife and local and migratory birds, Islamabad Deputy Commissioner (DC) Hamza Shafqat said that Islamabad was being turned green in line with the vision of Prime Minister Imran Khan. While talking to The Express Tribune, the official said that the plantation drives would mitigate environmental pollution in the capital territory.
