They circle and kettle in other circumstances as well, but no, they definitely do circle iver carcasses (and what may soon become so). It's a familiar site if you live around them.
Do you remember where you heard it's a myth? I'd be curious to see how that argument was made.
That's something they seem to do, for sure. It's just not the only thing.
They're not very vocal and are very social, so circling over carcasses might be a way to signal to others that they've found something.
They also form kettles as a big communal thing, too, for neither of those purposes. I've seen as many as 50 or 60 circling together for well over an hour, with no food nearby and no clearly no interest in going anywhere else.
(This is all turkey vultures in the US. These African vultures might have different behaviors, but I wouldn't be surprised if they are mostly comparable in terms of variety and sophistication)
I live in a place where Vultures are protected, so there's tons of them, and I have seen them circling in both cases, clearly hovering a carcass, but also randomly circling in numbers when no food is around...
And yeah, on close read, you'll see that they're all trying to communicate that you can't assume that the vultures are circling a carcass whenever you see them circling because they have other behaviors that involve circling as well. But it's an easy detail to miss in some of them for sure!
I feel that’s not quite right. The writing appears to indicate that circling a carcass is the small minority. They’re finding the carcasses by smell of decay.
I’ve read elsewhere vultures are actually good signals of gas leaks for this reason.
They don’t have much of a reason to circle a carcass they intend to eat unless perhaps it’s a lagging indicator and they’re leaving the carcass. They don’t circle dying things because they don’t have the means to detect dying things.
I’m not convinced circling vultures is a good sign that there’s a carcass below them.
Myth or not, the poachers believe it and murder the vultures as a result.
I’ve worked with vultures at a raptor conservancy. They are social, curious and intelligent birds. I have very fond memories of an Egyptian vulture named Boe who would unfailingly undoe my shoelaces when I entered her aviary. I love these birds
As someone who lived near Egyptian Vultures and Eurasian Black Vultures (Aegypius monachus), I can assure you they do. But that's not the only reason for them to do so.
