Due to environmental change worldwide, day by day birds becoming coped up in their native land. The average temperature in Hemalya, Saiberia, Nepal, Zingiang and Mongoloia increased. Thus, some species are able to live in those regions during winter.

Although, birds hunting is prohibited by Law in Bangladesh. According to the wildlife protection and security 2012, birds hunting, confined in a case and sell is punishable offence. The highest punishment is 2 years detention with 0.2 million fines. But due to the lack of public awareness, people are still disturbing them in there wandering place, hunting and selling birds. The government should increase the awareness and enforce the Law properly to protect the ecosystem.
