This is with reference to a news item in your newspaper on January 20 regarding the potential threat of vultures hitting the airplanes and damaging their engines at Lahore airport. It may be clarified that vultures have almost become extinct in Pakistan and that is being attributed to the residual effect of a drug called 'dilcofonic' in carcasses of dead animals. To save this scavenger, WWF has launched a programme for breeding of captive vultures at the Changa Manga forest .The bird hits mentioned by your reporter are probably due to kites, the common bird found in this part of the world. The kite population has increased due to feeding of Sadqa meat at Ravi Bridge alongside the Lahore Branch Canal. This practice needs to be stopped forthwith. -QASIM IQBAL KHAN, Lahore, via e-mail, February 22.
