Thanks @Donna_Callais - that beak is something isn’t it? I have a couple not so crisp shots where it’s open slightly and the way it fits together when closed is something to see. They are formidable and something I never knew is that vultures depend on eagles, ravens and other scavengers to open the bodies of fresh cadavers with tough hides. Vultures aren’t strong enough to do it and would otherwise have to wait until the skin naturally softened. Kinda icky, but oddly interesting, too. And yeah, I’ll never leave the 100-400 behind again!
