Rather late than never! Now those are great shots of a Southern Red-billed Hornbill, and I also got one on camera many moons ago. I remember how I struggled to pronounce the second word of its specie name, as it was and still is a real tongue twister. (Tockus erythrorhynchus)
Congrats professor, and sorry about your battles with the camera.
