Gelada monkey giving birth - photos by @jtkerby - swipe for whole series | Prior to photographing this story for the magazine, I worked as a biologist in the Ethiopian Highlands. On this day, that training paid off when I noticed a female monkey acting oddly - she walked away from the herd on her own, not something adult females will often do. I had been following an Ethiopian wolf with fellow photographer @tbfrost, but quickly decided to figure out what this monkey was up to instead. It soon became apparent that she wasn't sick or hurt as I initially feared, but was about to give birth. I put on my telephoto lens, gave her some space, and watched the following sequence unfold. These photos capture the intimate moment when a new gelada joins the herd, but they are also quite useful for scientific purposes. It's rare to see a primate give birth in the wild, but over the past 10 years, researchers at the Guassa Gelada Research Project have documented 15 such occurrences at Guassa. An analysis of this dataset by project scientists tells us a more complex story about gelada births, and allows for detailed comparisons of the process with other primate relatives - including humans. For more on geladas and the Guassa, check out the full story in the April issue of #NatGeo with additional photos by @tbfrost and text by @craigwelch. #Ethiopia #Gelada #Guassa
