A critically endangered black rhino calf has been born at Kenya's Chyulu Hills National Park, marking the second such birth in less than two years and a significant boost for conservation efforts.

• The birth increases the population of Eastern black rhinos in the park to nine.
• The Big Life Foundation confirmed the birth, with rangers discovering the calf.
• The exact birthdate is unknown, though it occurred within the past six months, and the calf's sex is yet to be determined.
