Explore African wildlife and check out the vultures. South
Africa has a number of vulture species and tragically many are endangered or
close to being so. The Cape Vulture is one such and saw a massive decline not
long ago. The numbers are coming back up slowly and yet there is a long way to
go before we can breathe easy on their account.
Vultures have the best network in the animal kingdom. There
was a notable case where a vulture tagged in the morning at Pilanesberg
National Park was found late afternoon on a carcass in the Kruger park. A
distance of 500km and more. How did he show up? Let me tell you these guys are
Exploring Africa by air. They use rising air currents called thermals and soar to great heights without flapping a wing.
Each vulture keeps track of the ground underneath for feeding
opportunities and also keeps track of his buddies up to 10-15 km around him. So
each individual has a radius of about 10-15 km around him or her. So when one
drops down to a carcass soon the neighbours realize that he has moved and as
one moves downwards the neighbours start and …. You guessed it, their
neighbours and so on and on and on till out of a clear sky you have up to 100
vultures in a matter of a few hours sitting around on or near a carcass waiting
for the lions to finish so they can dig in. With cheetah kills they bully the
cheetah off and many cheetah kills are lost to vultures and of course the
ubiquitous hyena.
There is a catch though. Most vultures can’t really get into
a carcass if there was no major predator feeding on it first. So a giraffe for
example (in the pic) that died of natural causes would have to be opened up
before any can feed. The big shot who can actually do that is the Lappet faced
vulture with its huge strong beak and powerful body. Once it has been opened
then it’s a free for all.
The carcass as you can see in the picture has hardly been
opened at all. Giraffe skin is pretty tough and even 24 hours after the giraffe
died it has still not been exploited. Maybe the lappet’s are off on a jamboree
cuz they ain’t showed up yet, and the Cape vultures and their hooded vulture
pals are just hanging around waiting for a meal to be served.
This video of the buffalo that was killed by lions shows how
completely they can clean a carcass to the bone. Cape and hooded vultures are
very efficient scavengers when the carcass is opened up.
As we explore the cause of things, Africa becomes more and
more exciting and amazing and thrilling. Explore Africa and discover something
every day.
