Migratory birds flying in the open sky and swimming in the lakes of Jahangirnagar University is a common scene in winter. But this winter the guest birds did not arrive in time. They arrived at the campus in mid-December, five to six weeks later than their normal time of arrival. Normally, they arrive at the campus in November and stay till March.
The migratory birds started coming to JU since 1986 because of the nice environment and the JU authorities declared the campus safe abode for migratory birds. But recently, cutting down trees in a large scale without caring about the natural balance of the campus and commercial fish farming in the lakes have harmed the environment.
The Zoology department's yearly statistical report shows that the number of migratory birds is increasing every year. In 1990, 78 species of birds were identified, 133 species were seen in 2007, 144 species in 2008, 176 in 2009 and 186 in 2010. Of the birds, some 74 species now live in the campus permanently and breed.
Every year the guest birds come to JU from the cold regions of the world including Xinzian, Siberia, Greenland and India. More than two thousand birds including Khanjna, Porchard, Jalpipi, Chamot thuti, Sharali, Gargeni, Lenza and Shouvler come here to amaze the spectators.
