While driving from Ganpatipule to Ratnagiri I noticed a pair of hornbills flying over. Much against the wishes of my friends and family, I changed the course of my car and followed the 2 birds. They then perched on a cell phone signal tower. Was quite high but I could manage to record their call on my Blackberry. Converted from amr to mp3 online and amplified using grab-tube. I was standing by the road hence other disturbances may be heard. It almost seems similar to a donkey braying.
