At around 1250 hours on the 23rd July 2008, there was a loud call in my garden that I traced to a pair of Oriental Pied Hornbill (Anthracoceros albirostris). The birds were perching on the TV aerial on the roof of my neighbour’s house.
The male hornbill was calling on and off loudly with the female by his side (top left). The latter then preened the head of the former (top right) before joining in with a call of her own (below left).
The male then began preening himself, starting with his tail feathers and going on to his breast and then his wing feathers.
The female then joined in preening herself, starting with waxing her tail feathers with oil from the preen gland (top right).
After about five minutes, the female suddenly flew off followed by the male a few seconds later.
