Brilliant strategy i would say! Numbers do matter

Thanks for this interesting blog, Kate.
Though one sees impalas so often on a safari, their beauty and grace is always enchanting. And seeing a big herd moving through the high grasses at Londolozi is such a beautiful and peaceful sight.
Great that there chances of survival and even growth of numbers is so good there.

Incredible symmetry of the herd watching by Kate Arthur

It’s amazing to imagine the success rate of impalas reaching breeding age to be as high as 70% Kate!! Truly a testament to their durability as a species. Beautiful images as well!!!

They’re such beautiful creatures… evolution made them so, and it’s a pleasure to see them. They can’t escape wild dogs when running, what if they freeze among green bushes? Some antelope do that. The picture of the dogs tearing the lamb apart is so sad even if it’s natural. Escaping big cats is easier but with cheetah, that have a high success in catching antelopes. Thank you for talking of these fascinating animals

The impala lambs are so beautiful and agile and love playing with each other. They also group together and run about making as if they are doing races. Many predators kill the lambs which is very sad, but then that is also nature’s way of keeping the numbers of impala in check. Good to know that more than half of the lambs that are born survive to adulthood.

Kate, thank you for your insights on the impala.

This is a wonderful report Kate referencing the success rate of the Impala lambs each season. I was surprised to read that the trackers believe the success rate for lambs to reach adulthood is more like 60-70% as I had believed it was lower. I hadn’t factored in the sheer number of lambs born each year vs the number of predators. Considering the leopard, lion, cheetah, wild dog and hyena populations, it does make sense that more lambs will survive, than not. Thanks Kate!

Thanks for the interesting post Kate, it is amazing how the herds seem to have the ability to maintain. We wonder how many of them die from old age??
