<p>Davangere: The severe drought that hit Karnataka’s crops last year has harmed migratory birds as well, with the winter roosting sites reporting a decline in their number this time. </p>.<p>Every year, these birds fly from Central Asia to five locations in the state: Magadi lake in Gadag, Almatti backwaters in Bagalkot, Hadinaru lake in Mysuru’s Nanjangud, Kondajji lake in Davangere, and Kabini backwaters.</p>.<p>In addition to bar-headed geese, the waterbodies in the state are home to the northern pintail, lesser whistling ducks, black- and red-headed bunting, demoiselle cranes, white storks, shovellers and the garganey during winter.</p>.Bengaluru biologists spot new butterfly species in Coorg; first one in the Western Ghats in four decades.<p>Ornithologists attribute the drop in numbers to the fluctuating water levels in the lakes, overfishing and scarcity of food.</p>.<p>Magadi and Kondajji lakes have seen a 50% reduction in the number of birds, especially bar-headed geese, that migrate from Mongolia. </p>.<p>Forest department sources at Magadi lake reported a decrease in bird numbers over the years.</p>.<p>“We recorded around 12,000 birds before 2017, but the number has been steadily declining,” a source said.</p>.<p>S Shishupala, birder and microbiology professor at Davangere University, said that while climate change has altered the bird migration pattern globally, local factors have worsened the situation.
