Read: 'Neck-drooping posture in oriental White-backed vultures: an unsuccessful predictor of mortality and it's probable role in thermoregulation' by Martin Gilbert, Richard Watson and Munir Virani, for information on this topic.

I recently watched a documentary that said birds will use their own bodies as shade for their heads during very hot weather. This may be what these vultures are doing.

Hope it is just the heat stress. The heads drooping like this looks quite disturbing.
