The numbers of Siberian migratory birds recorded decreased due to poaching and climate change, although. These birds are now began go back, but Sindh Wildlife Department or any authority have no any certificate the records of these evacuee birds.
The data of these migratory birds can not be release as yet, although their arrival started from October. A large number of exotic & colourful birds including Harriers, Kindfishers, Flamingos, Falcons, Geese, Swans, Cranes, Mallards, Waders, Cormorant, Mallards, White Ibis, Herons , Spoonbills, Egrets and Flamingos spend their migrated periods at the wetlands of Khyber Pakhtunkhwa, Balochistan, Punjab and Sindh. These birds also spent 4 to 5 months at Guddo Barrage, Drigh Lake, Lake Mancher , Haleji Lake, Khanjer Lake and adjacent areas of Indus Delta.
Lack of proper maintenance of the said Wetlands by the number of birds has decreased significantly. According to the wildlife experts now these beautiful birds migrating India and Iran instead Pakistan. During the decade of 80’s and 90’s more than 12 million and 670 species of migratory birds arrived at the said lakes from Indus Migrated Route No.4
They Birds comes here from Siberia for search of food through a distance of 4 thousand kilometers off the coast of Pakistan and, to descend rivers and wetlands in Pakistan. In the first phase, the birds stay at the lakes in Kazakhstan followed by different ranges of Karakoram in Pakistan.
From 1986 to 1990, the largest bird stay at the lake Haleji, where installed a Birds Ranking Station, put on the rings in foot of some birds. In the 90 decade there was 223 species & 2 million birds arrived at the Lake Haleji. However, the shortage of water into Lake Haleji and poaching has reduced the numbers of Birds, while numbers of birds in the Lake Khanjer also decreased. These birds also sold in the different area in Badin
The wildlife experts say that if there was not stop the illegal hunting of birds in Sindh the arrivals of the migratory birds will be turned off.
few years ago 670 species more than 12 million migrated birds came in pakistan to different province and wetlands in winter season but last three years reported that the number of migrated birds are reduced the reason is the route of migrated birds is afghanistan and this route is dangerous for birds because of war and birds change their route to iran and india,due to climate change in the wetland of pakistanshortage of water and seafood therefore migrated bird change their route one more reason is that due to climate change the summer season come early and when the summer start in pakistan at that time the winter season is not ending at siberia which are not suited for these birds that’s why they go that places where summer does not start early sindh wild life allocated the fund for the betterment of wetlands,hope that the condition would be better in future
