I posted one of these Birds earlier, cant remember where.
Lappet Faced Vulture, Trying to shoot these Birds gave me a new respect for Gary Samples and his Eagle Images, although these Guys come in slow & steady like a 747, they still present problems that give a healthy respect for People that consistently shoot amazing BIF Images.
Shot in Tanzania June 2013, 1Dx 200-400f/4 @ 280mm, probably the one place I felt I could have used the 600f/4 on this trip.
Another Bird that's heading to Extinction due to Poisoning, Habitat removal and general dislike.
These Guys when they turn up just own the Kill, they are the Largest and definitely the most aggressive, but strangely they are the first to Fly away when you approach them. Someone said they are a "Fugly Bird", but they are Majestic in Flight.
