February is a special time on the Serengeti. Right now its population of some 1.5 million wildebeests are giving birth to an estimated 8,000 calves a day, the Tanzania Daily News reports.
The East African nation has seen some 16,500 tourists come to watch the event in Serengeti National Park, including 5,800 domestic visitors who are part of a growing African middle class that’s boosting tourism across the continent.
This mass calving happens every year. All the pregnant wildebeests give birth within the same period of a few weeks, a process called “synchronized calving.” The animals give birth while standing up or even moving around, and wildebeest calves are walking within a couple of minutes. Once all the pregnant wildebeest have calved, the whole herd heads out.
These adaptations help protect the calves from predators. You can bet that hyenas, lions and other sharp-toothed critters are flocking to the area along with the tourists. Wildebeests are also hunted by humans to make a kind of jerky called biltong. This is legal in some parts of Africa although, of course, not in the park. One Tanzanian scientist estimated that half the calves will get eaten or die from other causes during the wildebeest’s 600-mile migration.

Zimbabwe has seen an increase in rhino poaching this year, the government newspaper The Herald reports.
At least 23 of the 700 or so black and white rhinos in the country were poached this year, but authorities managed to arrest 37 poachers and horn dealers. Rhino horns are popular for folk medicine, especially in Asia where they fetch high prices. One tactic of the poachers is to poison water holes, which kills not just the rhinos but any animal that drinks there.
More than $4 million is being spent to protect the animals, the government says, including implanting radio transmitters into the horns of 100 rhinos this year.
Zimbabwe isn’t the only country facing this problem. The Huffington Post reports that South Africa is doing more to train park workers on how to investigate incidents of poaching. Several poachers were killed in shootouts with authorities earlier this year, but that didn’t stop 341 South African rhinos from being poached in the first 10 months of the year, more than in all of 2010.
