Vultures aren't predators!
They don't harm or kill any other animals, they just do the cleaning up. So they'll be useful if any of the other creatures sadly expire after a surfeit of cake or the cats get them. It's not their fault they've got hygienic heads and bad PR.
If you remain unconvinced, I recommend a visit to Muncaster Castle Their flying display features diverse birds, including a trio of engagingly gawky teenage vultures.

(Go when the rhododendrons and bluebells are out, it's got a glorious bluebell wood)
