A male Bornean orangutan was born on April 2 at Madrid Zoo Aquarium, offering a rare conservation milestone for one of the world's most threatened primates. The newborn, weighing approximately 1.5 kilograms, was delivered by mother Surya after an eight-and-a-half-month pregnancy and is described by keepers as healthy and feeding well — a critical sign of normal development. Bornean orangutans (Pongo pygmaeus), native to the island of Borneo and parts of Sumatra, are classified as critically endangered by the International Union for Conservation of Nature due to rapid habitat destruction and illegal wildlife trade; the species reproduces slowly, with females giving birth at most once every six years.
