What percentage of Blue Wildebeest calves are born within the tight two-to-three-week calving period?

Answer

Approximately 80 percent

The reproductive strategy of the blue wildebeest involves a highly synchronized calving period designed to overwhelm predator capacity. Females time their conception seasonally so that births coincide with the onset of the rainy season when grass resources are plentiful for nursing mothers. This results in a dramatic mass birthing event where approximately 80 percent of all calves arrive within a very narrow window, typically spanning just two to three weeks. During the peak of this rush, output can reach approximately 8,000 newborns every single day.
