More than 500 birds got injured by glass-coated Manjha used in flying kites this season in Gujarat's Vadodara. The rescued birds were admitted to bird hospital for recovery. The pigeons are the most seriously injured among other birds due to thread. Some birds have even died because of the density of kites were high in the sky in Makar Sankranti season. NGO workers are helping in recovering birds from the spot. Chinese thread is said to be most fatal for these birds.
